Back in February, I wrote about EMC Isilon OneFS release notes and hinted that we’d be making changes to the format to improve their usability. I’m happy to announce that these changes are now in place and that you can see them in the OneFS 7.1.1 release notes.

What’s Changed

We’ve merged all of the release notes pertaining to a release branch (for example, 7.1.1) into a single document. This means that the 7.1.1 release notes contain all of the information about this OneFS branch from OneFS 7.1.1.0 (released in August 2014) through 7.1.1.5 (released in June 2015).

The new document includes:

  • All the new features that were introduced in OneFS 7.1.1.0 through OneFS 7.1.1.5
  • All the issues that have been addressed in in OneFS 7.1.1.0 through OneFS 7.1.1.5
  • All the functionality changes that were introduced in in OneFS 7.1.1.0 through OneFS 7.1.1.5

What’s New

To improve the document’s usability, we defined a list of functional areas. And, to help ensure that the functional areas are well understood, we included the full list of functional areas and their definitions at the end of the release notes. For example, the functional area of SMB encompasses new features, changes, and issues that affect SMB environments.

The content in the release notes is organized first by release number (for example, OneFS  7.1.1.2)  and then by functional area. This means that if you want to know if there are any new features, resolved issues, or changes in functionality that affect a particular area, such as SMB, in a specific OneFS release, such as 7.1.1.5, you can use the bookmarks pane or the table of contents to easily find that information.

Here’s an example of what you’ll find in the new table of contents (TOC):

OneFS 7.1.1-7.1.1.5 release notes

And here’s an example of what you’ll find in the Adobe Acrobat or Adobe Reader bookmarks pane:

OneFS 7.1.1-7.1.1.5 Bookmarks

We’ve also added an introductory section for each chapter, describing what you can expect to find there.

The new document also highlights the Target Code release. This change helps you understand how the Target Code release relates to other releases in the branch.

What did we gain?

Before making these changes, if you wanted the full picture of a OneFS release or maintenance release, you’d have to download two or three documents and piece them together. Each document contained some unique information, such as new features, and some overlapping information, such as known issues. The differences weren’t always obvious.

Now all of the information is in a single document that clearly identifies the release in which a fix, a change, or a feature was introduced.

In addition, the release notes previously contained multiple, lengthy tables that were sorted by a cryptic ID number. If you wanted to find issues related to a specific area of operation, you’d have to do a keyword search and collect bits and pieces of information scattered throughout the document.

Now the information is categorized first by the release in which the feature, fix, or change was introduced, and then categorized into tables according to the functional area that the feature, fix, or change affects. The new tables are small and easily scanned, and the information they contain is tightly focused.

How we did it

Developing the new release note format was a team effort involving writers, an information architect, and members of our user experience team.

We conducted user testing and issued a survey about the new format to confirm that the changes we planned to implement were in fact improvements that would benefit our readers. The feedback we received from user testing influenced the development of the document.

For example, one of our concerns early on was that the document was too long. However, user testing indicated that our users don’t read the document from beginning to end. Their chief concern is finding specific pieces of information easily, and they tend to jump from one place to another using keywords, the table of contents, or the bookmarks pane. So document length is not an issue.

Also, we had initially planned to separate new features from changes in functionality. User testing showed that our readers expected to find all of the new and changed features and functionality in the same chapter.

The most striking piece of feedback? Categorizing the information by functional area scored as a significant improvement for all of our testers.

Here are some of the usability testers’ comments:

  • “This is so great! Seriously. This is so much more legible and issues are so much easier to find.
  • “For me the redesign is a massive improvement over the current format. I hope this new format can be the new standard.”
  • “Known issues clearly separated by topic is a huge gain in usability. A consolidated listing of known and resolved issues for the major + each MR in one location is a time saver. If I have to attempt several keyword searches to find what I need, it takes me only 50 percent the time to do this in a combined doc.”

What’s next

As of today, the new release note format has been implemented in the OneFS 7.1.1.0 – OneFS 7.1.1.5 release notes. By the end of July, the new format will be implemented in release notes for the OneFS 7.2.0 branch as new versions of OneFS are released, the new release note format will be used to document those releases.

A new project to evaluate whether the new format can be applied to the release notes for other EMC products will be underway soon.

We’d like to hear from you about the changes and how they affect your ability to use the OneFS 7.1.1 release notes.  You can provide feedback by taking the short survey located here:

Cluster capacity advice from an EMC Isilon expert

Kirsten Gantenbein

Kirsten Gantenbein

Principal Content Strategist at EMC Isilon Storage Division
Kirsten Gantenbein
Kirsten Gantenbein

Avoiding scenarios where your cluster reaches maximum capacity is crucial for making sure it runs properly. Our Best Practices for Maintaining Enough Free Space on Isilon Clusters and Pools guide contains information to help Isilon customers keep their clusters running smoothly.

However, there are common misperceptions about cluster capacity, such as the notion that it’s easy to delete data from a cluster that is 100 percent full. Another misunderstanding: using Virtual Hot Spare (VHS) to reserve space for smartfailing a drive is not always necessary.

To clarify these issues and other concerns about cluster capacity, I interviewed one of Isilon’s top experts on this topic, Bernie Case. Bernie is a Technical Support Engineer V in Global Services at Isilon, with many years of experience working with customers who experience maximum cluster capacity scenarios. He is also a contributing author to the Best Practices for Maintaining Enough Free Space on Isilon Clusters and Pools guide. In this blog post, Bernie answers questions about cluster capacity and provides advice and solutions.

Q: What are common scenarios in the field that lead to a cluster reaching capacity?

A: The typical scenarios are when there’s an increased data ingest, which can come from either a normal or an unexpected workflow. If you’re adding a new node or replacing nodes to add capacity, and it takes longer than expected, a normal workflow will continue to write data into the cluster—possibly causing the cluster to reach capacity. Or there is a drive or node failure on an already fairly full cluster, which necessitates a FlexProtect (or FlexProtectLin) job from the Job Engine to run to re-protect data, therefore interrupting normal SnapshotDelete jobs. [See EMC Isilon Job Engine to learn more about these jobs.] Finally, I’ve seen snapshot policies that create a volume of snapshots that takes a long time to delete even after snapshot expiration. [See Best Practices for Working with Snapshots for snapshot schedule tips.]

Q: What are common misperceptions about cluster capacity?

A: Some common misconceptions include:

  • 95 percent of a 1 PiB cluster still leaves about 50TiB of space. That’s plenty for our workflow. We won’t fill that up.
  • Filling up one tier and relying on spillover to another tier won’t affect performance.
  • The SnapshotDelete job should be able to keep up with our snapshot creation rate.
  • Virtual Hot Spare (VHS) is not necessary in our workflow; we need that space for our workflow.
  • It’s still very easy to delete data when the cluster is 100 percent full.

Q: What are the ramifications of a full cluster?

A: When a cluster reaches full capacity, you’re dealing primarily with data unavailable situations—where data might be able to be read, but not written. For example, a customer can experience the inability to run SyncIQ policies, because those policies write data into the root file system (/ifs). There’s also the inability to make cluster configuration changes because those configurations are stored within /ifs.

Finally, a remove (rm) command for deleting files may not function when a cluster is completely full, requiring support intervention.

Q: What should a customer do immediately if their cluster is approaching 90-95 percent capacity?

A: Do whatever you can to slow down the ingesting or retention of data, including moving data to other storage tiers or other clusters, or adjusting snapshot policies. To gain a little bit of temporary space, make sure that VHS is not disabled.

Call your EMC account team to prepare for more storage capacity. You should do this at around 80-85 percent capacity.  It does take time to get those nodes on-site, and you don’t want any downtime.

VHS in SmartPools settings should always be enabled. The default drive to protect is 1 drive, and reserved space should be set to zero. For more information, see KB 88964.

VHS options should always be selected to set aside space for a drive failure. You should have at least 1 virtual drive (default value) set to 0% of total storage. For more information on these default values, see KB 88964 on the EMC Online Support site.

Q: What are the most effective short-term solutions for managing or monitoring cluster capacity?

A: Quotas are an effective way to see real-time storage usage within a directory, particularly if you put directories in specific storage tiers or node pools. Leverage quotas wherever you can.

The TreeDelete job [in the Job Engine] can quickly delete data, but make sure that the data you’re deleting isn’t just going into a snapshot!

Q: What are the most effective long-term solutions to implement from the best practices guide?

A: Make sure you have an event notifications properly configured, so that when jobs fail, or drives fail, you’ll know it and can take immediate action. In addition to notifications and alerts, you can use Simple Network Management Protocol (SNMP) to monitor cluster space, for an additional layer of protection.

InsightIQ and the FSAnalyze job [which the system runs to create data for InsightIQ’s file system analytics tools] can give great views into storage usage and change rate, over time, particularly in terms of daily, monthly, or weekly data ingest.

Q: Is there anything you would like to add?

A: Cluster-full situations where the rm command doesn’t work are sometimes alarming. In a file system such as OneFS, a file deletion often requires a read-modify-write cycle for metadata structures, in addition to the usual unlinking and garbage collection that occurs within the file system. Getting out of that situation can be challenging and sometimes time-consuming. Resolving it requires a support call—and a remote session, which can be a big problem for private clusters.

Sometimes accidents happen or a node can fail, which can push a cluster to the limit of capacity thresholds. Incidents such as these can occasionally lead to data unavailability situations that can halt a customer’s workflow. Being ready to add capacity at 80-85 percent can prevent just this sort of situation.

Racking EMC Isilon nodes

Kirsten Gantenbein

Kirsten Gantenbein

Principal Content Strategist at EMC Isilon Storage Division
Kirsten Gantenbein
Kirsten Gantenbein

With EMC® Isilon® scale-out storage, it’s easy to add performance and capacity to your cluster simply by adding new nodes. For example, after you acquire a new node, a certified technician locates an open space in a rack (either 2U or 4U, depending on the node size), installs rails, installs the node into the rack, connects the network and InfiniBand cables, and then joins the node to the cluster. After joining the node, you’ll have more space and performance capacity right away.EMC Isilon 4U rail kit installation

The node installation process is simple and fast; but be sure to take the time to check that the nodes are safely secured to the rails and rack to minimize the risk of personal injury and damage to equipment.

Check out the following videos, which show the proper procedures for racking EMC Isilon 2U and 4U nodes, including both node installation and node removal from a rack.

Installing a node into a rack

Isilon nodes mount in a standard 19-inch wide rack and use a sliding rail system. Watch the following videos to learn how to install 2U and 4U nodes into a standard rack with 3/8-inch square holes.

For written descriptions of these procedures, see the EMC Isilon 2U rail kit installation guide and 4U rail kit installation guide, which are available on the EMC Online Support site (login is required).

Removing a node from a rack

If you need to remove nodes from the rack to service them or because you’re relocating your cluster, it’s important to be sure that you always shut down nodes as described in the knowledge base article, How to safely shut down an Isilon cluster prior to a schedule power outage (16529). If you don’t shut down a node properly, you increase the risk of data loss.

After the node is shut down, you can remove a 2U node and a 4U node from a rack. Watch the following videos to learn the safest way to remove these nodes from a rack.

For written descriptions of these procedures, see the node removal guides on the EMC Online Support site.

If you’re in the market for a new data storage solution, such as an EMC® Isilon® scale-out network attached storage (NAS) system, you’ve probably done a good amount of research to determine which solution will best meet your needs.

One important area of research is determining if your data center is ready for an EMC Isilon cluster. The Isilon Site Preparation and Planning Guide (login with an EMC Community Network account required) can help answer important questions about how to prepare a data center infrastructure for new Isilon equipment. Designed for system administrators or facility managers, this guide offers specific information about environmental and power requirements for data centers.

The information in this guide extends beyond providing site requirements. It’s also a useful reference for selecting equipment and preparing for the arrival and set up of your new cluster.

Selecting the right equipment

EMC Isilon NodesThe Isilon Site Preparation and Planning Guide is a singular resource for specifications and recommendations about all the equipment that makes up an Isilon cluster.

For example, this guide includes specifications for the following:

  • Nodes: Get specs on storage capacity, dimensions, and more for all supported nodes including S210, S200, X200, X410, X400, NL400, and A100 accelerator nodes.
  • Rack cabinets: Learn about standard storage racks requirements and delivery dimensions.
  • Cables: Get recommendations for managing InfiniBand and Cat 5 cables. For demonstrations of proper cable management, watch the EMC Isilon Site Preparation and Planning: Cabling video.

Installing your cluster

For an overview of cluster installation basics, such as topology, node positioning, and planning for expansion or service needs, watch the EMC Isilon Site Preparation and Planning: Cluster Installation video.

To help you with the installation process, Isilon Professional Services can assist you with setting up your new Isilon cluster to meet the needs of your specific workflows. The Isilon Site Preparation and Planning Guide provides a list of what to consider when first installing your cluster, which you can review with your Professional Services account representative:

  • Which version of the Isilon OneFS® operating system to install on the cluster
  • Network connectivity details, including IP ranges, for your cluster nodes, client, and InfiniBand networks
  • DNS configuration details, including name servers and search lists
  • Directory services such as Active Directory, LDAP, NIS, or local user groups
  • File sharing protocols such as SMB and NFS, and advanced file sharing options
  • Data protection levels, anti-virus solutions, NDMP backup, and auditing
  • Cluster alert solutions such as ESRS and SNMP monitoring

Principal Content Strategist at EMC Isilon Storage Division
Kirsten Gantenbein
Kirsten Gantenbein

EMC® Isilon® patch documentation has been updated, making it easier to find information about patches for the OneFS operating system. Previously, you had to check several separate documents for each supported version of OneFS to determine if a patch was available for a specific known issue. Now you can refer to a single document, Current Patches for EMC Isilon OneFS, (log in to the EMC Online Support site is required) to find information about any patch for any version of OneFS.

The best way to resolve known issues in OneFS is to upgrade to a recent OneFS maintenance release (MR). However, if you need a solution before an MR is released and a patch is available, you can download and install a patch. Often, Isilon will issue a standard patch for a specific issue or a rollup patch to fix issues within a component of OneFS. (Not every known issue is addressed with a patch.)
This consolidated document provides the benefit of reviewing all available patches of versions of OneFS. This can help you consider which version of OneFS that you want to upgrade to next.

All OneFS patches and current patch documentation are on the EMC Online Support site. For example, if EMC Isilon Technical Support provides your with a patch ID number, you can search for it in EMC Online Support by entering “patch-[ID number],” as shown in the image below. Or you can check the new reference, Current patches for OneFS. This document provides a current list of patches available for supported versions of OneFS.
