How to recover Gluster 3.1 VM?

Hello Community,

I have 4 VMs running Gluster 3.1 to form a single storage volume but one of them cannot boot after a week of shutdown.

It keeps running Gluster 3.1 status bar and then freeze and become black. I cannot ping it and Gluster platform management console cannot connect to it too. We have some data on the volume to recover. what is the best solution to solve this?

Gluster Releases Continuous Data Replication Enabling Business Continuity in the Cloud

Today marks an important milestone in the evolution of Gluster as the storage operating system for public and private clouds. As part of our release of Gluster 3.2, we now have the ability to support Continuous Data Replication (CDR).

As I discussed in my previous post, failures of one form or another are endemic to data center operations.  Most frequently—the failures are limited to systems within a data center;  disks or servers fail, administrators trip over power cords, networks get segmented, etc.  Gluster has long had a series of internal features to minimize the frequency and impact of those failures, including our no-metadata architecture, self healing features, support for RAID 5 &6  within a node, and—of course—the ability to do n-way synchronous replication between nodes.

On occasion, however, failures affect an entire data center. Power lines can get cut, blizzards can keep employees from the data center, and fires, floods, or other natural disasters can take out the entire data center. Of course, the recent issues at AWS illustrated this point.

To prepare for such data-center level failure, it is necessary to support data replication across geographic regions. Gluster’s recently announced Continuous Data Replication allows our private cloud customers to asynchronously replicate a) between data centers across the WAN or b) between their data centers and a public cloud, such as Amazon Web Services. Similarly, Gluster’s public cloud customers can now not only replicate between availability zones in a geographic region, but also between regions.

Gluster Continuous Replication

Generally speaking, the connectivity between geographic regions is slow, expensive, and subject to interruption. If you are storing hundreds of terabytes or petabytes, you need to be sure that replication is both continuous and efficient.  Replication should be continuous because a) it is impractical to snapshot and replicate terabytes of data on a regular basis, and b) because the time required to either back up or restore in the event of an incident is often too long for the real-time availability requirements of most enterprises. Similarly, replication should be efficient, because the cost of snapshotting and replicating large data sets can be extremely expensive in terms of both storage and I/O.

Gluster’s Continuous Data Replication meets both requirements. Gluster’s CDR provides continuous, asynchronous and incremental replication service from one site to another over local area networks (LANs), wide area networks (WANs), and across the Internet. Only incremental changes are replicated, eliminating the need for snapshot-like copies of whole files or volumes. In addition, 3.2 features intelligent asynchronous replication in which GlusterFS tracks changes to the primary data and replicates in real time across a WAN. Changes are tracked and queued to ensure data stays synchronized regardless of latency or potential network interruptions.

Ultimately, the significance of CDR goes beyond availability. For the vision of hybrid clouds to fully develop, we must support the ability not only to migrate applications from one data center to another (e.g. VM Migration), but also must make sure that application data is available. While it may be practical to migrate Virtual Machine images on a moment’s notice, it is not practical to migrate terabytes or petabytes of application data at a moment’s notice. Therefore, we need to make sure that that application data is available and waiting in multiple data centers, and that the costs of doing so are not prohibitive.  More information on that in a subsequent post.

Gluster Introduces New Storage Software Appliance for Private Cloud and On-Premise Data Centers

New software-only appliance enables creation of storage pool from any bare metal hardware on the Red Hat HCL

Sunnyvale, Calif. – May 3, 2011 – Gluster, the leading provider of scale-out, open source storage solutions for public and private clouds, today announced the availability of the Gluster Storage Software Appliance, dramatically extending the range of commercially supported configurations for Gluster in the private cloud and on-premise data center environments. This new product combines a prepackaged operating system with GlusterFS and can be deployed on any Red Hat Hardware Compatibility List (HCL) certified host server and its certified storage.

In both public and private clouds, Gluster provides enterprises with the ability to combine commodity compute and storage into a virtualized, standardized, and centrally managed storage pool that can flexibly scale to petabytes of capacity, GB/s of throughput, and N-way availability. Prior to the release of the Storage Software Appliance, Gluster was available for deployment in: public clouds, as an Amazon Machine Image or RightScale Server Template; in private clouds, as a virtual storage appliance on top of hypervisors such as VMware, KVM, or Xen; or as a non-commercially supported implementation of the open source GlusterFS.

As of today, a fourth deployment option is available. Customers running private clouds or on-premise data centers can now obtain commercial support for Gluster deployed as a software appliance in a non-virtualized, bare metal environment.

In on-premise, private cloud environments Gluster offers up to three times the performance at one-third the cost of proprietary and monolithic scale-up storage solutions. Like all Gluster solutions, the Gluster Storage Software Appliance is POSIX-compliant and does not require applications to be rewritten. Users of the Storage Software Appliance can aggregate CPU, memory, and capacity into a single global namespace, scale out capacity and performance linearly on-demand, and benefit from drastically improved storage economics via the use of commodity hardware.

“The increased use of cloud computing technologies in the private cloud and on-premise data centers has established a need in terms of cloud storage solutions specific to these environments,” said George Crump, president and founder of Storage-Switzerland. “The Gluster Storage Software Appliance is an excellent example of a solution designed for cloud environments that require high availability, performance and value. The choice to do all of this on Red Hat certified hardware makes the value and usability of the solution even more compelling.”

The Gluster Storage Software Appliance incorporates the latest version of GlusterFS (version 3.2), which includes:

  • Geo-Replication – providing continuous, asynchronous and incremental replication service from one site to another over local area networks (LANs), wide area networks (WANs), and across the Internet. Only incremental changes are replicated, eliminating the need for snapshot-like copies of whole files or volumes. In addition, 3.2 features intelligent asynchronous replication in which GlusterFS tracks changes to the primary data and replicates in real time across a WAN. Changes are tracked and queued to ensure data stays synchronized regardless of latency or potential network interruptions.
  • Easily accessible usage quotas – with the ability to set quota on usage of disk space by directories or volumes. Storage administrators can control disk space utilization at the directory and/or volume levels with Gluster by setting limits to allocate disk space at any level in the volume and directory hierarchy. This is particularly useful in cloud deployments to facilitate the utility billing model.
  • New monitoring and management tools (Gluster Top and Profile) – that provide familiar monitoring and statistics capabilities for I/O operations and performance statistics. Gluster Top presents the top 100 operations per server, providing visibility into the I/O workload pattern. Gluster Profile provides performance statistics over a user-defined time period for metrics including latency, number and type of calls, and amount of data read or written.

“The industry is becoming increasingly savvy to the fact that storage technology can make or break a public or private cloud deployment,” said Ben Golub, president and CEO at Gluster. “Our new Storage Software Appliance delivers highly available, scale-out, on-demand storage technology that can integrate seamlessly with Red Hat technology in any private cloud or on-premise storage environment.”

Pricing &Availability

The Gluster Storage Software Appliance will be generally available on May 16, and it can run on any hardware on the Red Hat Hardware Compatibility List. For sales inquiries contact sales@gluster.com or for more information visit www.gluster.com.

Gluster Releases Continuous Data Replication for Public and Private Cloud Storage

Latest release adds asynchronous geographic data replication for public and private clouds, as well as powerful new quota and management tools

Sunnyvale, Calif. – May 3, 2011 – Gluster, the leading provider of scale-out, open source storage solutions for public and private clouds, today announced the general availability of GlusterFS 3.2. This latest release includes Continuous Data Replication, which enables multi-site data protection for public and private clouds. In addition, the update includes enhanced multi-tenant management for public and private clouds, with usage quotas and new monitoring tools for improved visibility into I/O operations profiles and performance statistics. Version 3.2 of Gluster is available for the full line of Gluster solutions, including those for public clouds (the Gluster AMI and Rightscale Template) and private clouds (the Virtual Storage Appliances for VMware, KVM, and Xen, and the recently announced Gluster Software Appliance). The open source version of GlusterFS 3.2 was also released to the community.

Gluster’s software-only storage solutions give enterprises the ability to treat physical storage as a virtualized, standardized and scale-on-demand pool in much the same way they treat computing resources today, radically improving storage economics in the process. Gluster frees enterprises from the constraints of proprietary, monolithic storage architectures by enabling them to create scalable, high performance, and highly available storage either in the public cloud or on their choice of commodity hardware within the data center. Gluster delivers fully functional, fully POSIX-compliant storage solutions that pool storage resources under a global namespace, delivering high availability, linearly scalable performance and capacity, as well as elastic volume management, which enables data growth and migration to be easily managed with no downtime.

“As an increasing number of companies are moving into the implementation phase of cloud computing, they are quickly realizing the crucial role storage plays in ensuring the deployment is successful,” said George Crump, president and founder of Storage-Switzerland. “The latest product release by Gluster includes a number of key features for more effective business use of cloud storage, including continuous data replication, making the decision easier for enterprises to employ cloud computing in their overall IT strategy and within their enterprise data centers.”

Features of the new 3.2 release include:

  • Geo-Replication – providing continuous, asynchronous and incremental replication service from one site to another over local area networks (LANs), wide area networks (WANs), and across the Internet. Only incremental changes are replicated, eliminating the need for snapshot-like copies of whole files or volumes. In addition, 3.2 features intelligent asynchronous replication in which GlusterFS tracks changes to the primary data and replicates in real time across a WAN. Changes are tracked and queued to ensure data stays synchronized regardless of latency or potential network interruptions.
  • Easily accessible usage quotas – with the ability to set quota on usage of disk space by directories or volumes. Storage administrators can control disk space utilization at the directory and/or volume levels with Gluster by setting limits to allocate disk space at any level in the volume and directory hierarchy. This is particularly useful in cloud deployments to facilitate the utility billing model.
  • New monitoring and management tools (Gluster Top and Profile) – that provide familiar monitoring and statistics capabilities for I/O operations and performance statistics. Gluster Top presents the top 100 operations per server, providing visibility into the I/O workload pattern. Gluster Profile provides performance statistics over a user-defined time period for metrics including latency, number and type of calls, and amount of data read or written.

“Gluster has long believed that that storage must change radically to match both the architectures and economics of the cloud” said Ben Golub, president and CEO at Gluster. “With this release, we not only provide the fastest path to public and private cloud storage, we also provide a powerful set of tools for connecting public and private clouds.”
In both public and private clouds, Gluster enables enterprises to scale on demand to petabytes of capacity and GB/s of throughput on commodity physical and cloud hardware, yielding unrivalled economics in the process. Now, Gluster also enables enterprises to scale out availability on-demand, enabling both Synchronous N-way replication within the data center and across high-speed links, and Asynchronous Geo-Replication between data centers across WANs. For public clouds such as Amazon Web Services (AWS), GlusterFS is packaged in an Amazon Machine Image (AMI) for deployment in the AWS cloud. The Gluster AMI is the only way to deploy high-availability storage within AWS and deliver predictable high performance during rapidly changing and demanding workloads. For private clouds, the Gluster Virtual Storage Appliances integrate GlusterFS into a virtual machine for deployment on popular hypervisor environments such as Red Hat KVM, VMware ESX and Citrix Xen and run on the enterprise’s choice of certified hardware platforms.

The newly announced Gluster Storage Software Appliances for private cloud and on-premise data centers combine a prepackaged operating system with GlusterFS and can be deployed on any Red Hat Hardware Compatibility List (HCL) certified host server and its certified storage, bringing unrivaled high availability, performance, scalability and the cost savings benefits of commodity to the private cloud and data center.

“Since we announced our Storage Appliances in February, we have received extremely positive feedback from our customers and the community,” said AB Periasamy, co-founder and CTO of Gluster. “We continually strive to enhance our solution and make it as comprehensive as possible for public and private cloud, such as adding these new data replication and management capabilities.”

Gluster Chief Technology Officer to Present at OpenStack Design Summit and Conference

Innovative cloud storage provider to discuss petascale filesystems and disclose use-cases in public and private cloud environments

Santa Clara, Calif. – April 25, 2011 – Gluster, the leading provider of scale-out, open source storage solutions for public and private clouds, today announced its co-founder and chief technology officer, Anand Babu (AB) Periasamy, will be among the industry experts to present at the 1st OpenStack Design Summit and Conference taking place April 26 – 27 at the Hyatt Regency in Santa Clara.

Periasamy will present “Petascale Cloud File-System Design and Implementation” on Wednesday from 10:30 a.m. to 11:00 a.m. During his session, Periasamy will discuss how filesystems are under tremendous architectural strain as the explosion of unstructured data continues unabated and traditional filesystem architectures fail to meet the demanding challenges of both public and private clouds. He will explain the petascale filesystem architecture and how it is designed to easily handle massive amounts of unstructured data, as well as provide high availability and linearly scale performance and capacity in order to efficiently manage unplanned spikes in performance, providing high availability as a standard function of the filesystem.

“Traditional and hybrid filesystems are not meeting demands and even worse, are creating limitations. The petascale filesystem is designed to fluidly handle an immense amount of unstructured data while linearly scaling performance and capacity,” said Periasamy. “My presentation will give attendees some best practices for building such a system in their own environments and will discuss detailed use-cases, specifically for public and private cloud environments.”

Prior to Gluster, Periasamy served as CTO at California Digital Corporation and, in 2004, led the development of the world’s second-fastest supercomputer, “Thunder,” for Lawrence Livermore National Laboratory. Periasamy also serves on the board of “Free Software Foundation – India.”

Viability of Cloud Services Remains Strong

The outage at one of the Amazon Web Services (AWS) data centers last week has led many to question the viability of public cloud services as a whole.

As a company that provides storage solutions for private and public clouds (including AWS), we would respectfully disagree.

Failures of one form or another are endemic to data center operations. Routinely, servers and disks fail, power lines get cut, surges in usage overwhelm available resources,  blizzards keep employees from getting to the data center, etc. Less routinely,  floods, fires, natural disasters, or 9/11-type events take out entire data centers.

The question should really not be “Can failures occur in the public cloud?” Of course, failures will occur. The real questions should be  “How frequently do those failures occur?” “How easy is it to minimize the impact of those failures?” and “How expensive is it to reach a particular availability level?”

While the outage at the AWS data center yesterday garnered a lot of attention (no doubt because of the high profile of impacted customers like Reddit and Quora, it is worth noting that several high profile services that run their own data centers (Twitter, Gmail, etc.) have experienced similar failures over the past several months. Moreover, I would bet that  most of the customers at this particular data center would have experienced far more frequent and serious failures had they been running their own operations.

There are several reasons for this:

a) Because of economies of scale, Amazon can invest far more in robust and redundant power supplies, cooling equipment, physical and logical security, etc. than a typical, self-run data center. They can also invest more in monitoring services and employees to respond to device failures.

b) Because of the basic Amazon infrastructure (as well as supporting technologies such as Gluster), it is possible  to distribute workloads across multiple devices (thus minimizing the impact of any particular device failing)

c) Because of the basic Amazon infrastructure (as well as supporting technologies like Gluster) it is easy to flexibly and quickly provision additional resources to handle usage spikes

d) Because implementing all of the above would be out of the budgets of many organizations.

All of the above items relate to the frequency and impact of failures within a particular data center.

It is important to note that with AWS (and Gluster), companies also have the ability to minimize the impact of the failure of an entire data center .

Within any AWS geographic region (e.g. East, West, Europe, Japan), there are multiple availability zones. These are physically separate data centers, (with separate power supplies, water supplies, personnel, etc) that have high bandwidth connections. Because Gluster makes it possible to easily and instantly replicate between 2, 3 or more availability zones, our customers in AWS East were not taken out by this incident, as their data was also replicated into availability zones that were not impacted.

Of course, there is always the possibility that large natural or man-made disasters could affect an entire geographic region. Fortunately, we are very close (in weeks) to offering the capability to easily keep data replicated and in sync across AWS regions and between a private cloud and a public cloud. Thus, even in the event of a wide spread natural disaster affecting an entire region, it will be possible (and economical) to ensure widespread geographic availability.

Stay tuned.

Gluster brings added value to Amazon Web Services (AWS) cloud.

Gluster Virtual Storage Appliances are specifically designed for public and private cloud and virtual machine (VM) environments. The appliances give enterprises the ability to treat physical storage as a virtualized, standardized, and scale-on-demand pool in much the same way that they treat computing resources today, radically improving storage economics in the process. With multi-hypervisor support, the Virtual Storage Appliance integrates GlusterFS into a virtual machine for deployment on any hypervisor or cloud platform.

“The popularity and rapid growth of the KVM and Xen communities over the years has been remarkable. In our discussions with our community and key partners, we recognized the crucial need KVM and Xen users have for scale-out cloud storage like our GlusterFS offering,” said AB Periasamy, co-founder and CTO of Gluster. “We are excited to announce this next step in our product roadmap and look forward to the opportunities it will provide. Many of our customers are already planning to extend the benefits they achieve with Gluster into a KVM or Xen environment.”

The Gluster Virtual Storage Appliances are:

  • Tailored for cloud and VM environments: The software-only appliances are decoupled from hardware and virtualize the underlying disk and memory resources in a unified global namespace, allowing for limitless scalability. With this feature, enterprises are able to deploy storage similar to virtual machines and eliminate the need for expensive physical monolithic storage systems.
  • Easy to deploy and scale: By scaling performance and capacity linearly, storage capacity is able to be added as required in only a few minutes without affecting performance.
  • Supportive of multiple hypervisors and workloads: This capability delivers excellent performance across a wide range of application workloads, including those found in highly virtualized environments.

Product Availability

Gluster Virtual Storage Appliances supporting KVM, VMware and Xen are now generally available. For more information, email sales@gluster.com.

Free 7-day Trial of Gluster on Amazon Web Services

We announced exciting news today for customers and community members who are interested in Public Cloud Storage.  Today, we announced that we will make up to 7 days of Amazon Web Services Elastic Compute Cloud (EC2) and Elastic Block Storage (EBS) usage free to people who are interested in trying Gluster’s Amazon Machine Image (AMI).

The integration of Gluster and Amazon Web Services is truly exciting, because it enables users to create a multi-client shared storage pool in the cloud that can scale to  petabytes and  that delivers performance, flexibility,  and availability that rivals on-premise deployments.

How does it work?  Quite simply, Gluster’s AMI aggregates the computing and I/O power of multiple EC2 instances and the capacity of multiple EBS volumes into a single, centrally managed global namespace. Each EC2 instance of Gluster delivers ~ 50 MB/s of throughput and petabytes of capacity.  So, adding capacity is simply a matter of adding additional EBS volumes to the cluster—and there are no practical limits. Adding performance is simply a matter of deploying across more EC2 instances. As shown in the graph below, by the time you’ve grown to 8 EC2 instances, you can expect nearly 300 MB/s of write throughput and nearly 500 MB/s of write performance. And, there are no practical limits to how many EC2 instances you can put into your cluster.  Finally, your data can be replicated across multiple instances and multiple Amazon availability zones (which are geographically separate data centers with separate power, management, etc.).

Literally, in less than one hour, users can scale to hundreds of terabytes and hundreds of MB/s of throughout, with n-way replication across multiple Amazon availability zones.  Equally important, usage (and economics) can scale up or down as your needs require.  Furthermore, since Gluster is POSIX compliant, and supports standard NAS and NFS protocols, there is no need to rewrite your applications.

All that was needed was to make the process of trying as simple and risk-free as possible. Now, not only are your first 30 days of Gluster free (no matter how many EBS & EC2 instances you use), but your first 7 days from Amazon are free as well.

We really appreciate Amazon’s partnership and commitment. We’ve seen a real spike in deployments since we first launched, and the feedback has been amazing.

Iron Mountain Digital Steps Out Of Cloud Storage; Nirvanix Steps In

Well, it appears again that companies that are good at one thing won’t necessarily be good at trying other things. Iron Mountain Digital, the public cloud offshoot from Iron Mountain–the company that stores papers in caves and giant vaults and drives around in vans all the time–has collapsed.
