The OneFS Job Engine primary functions.

OneFS Job Engine primary functions

In the EMC Isilon OneFS® operating system, the Job Engine manages the scheduling, reporting, and the initiation of cluster protection and maintenance tasks. A significant benefit of the Job Engine is that it can adaptively manage maintenance jobs based on the amount of cluster resources available.

To ensure that your cluster is performing at optimal levels, follow these Job Engine best practices:

  • Schedule jobs to run during your cluster’s low usage hours.
  • When possible, use the default priority, impact, and scheduling settings for each job.
  • Ensure that the cluster, including individual node pools, is less than 90 percent full.
  • If the EMC Isilon SmartPools™ software module for resource management is licensed, ensure that default spillover setting is enabled.
  • Set up notification rules to alert you when the cluster begins to reach capacity thresholds and enable virtual hot spares (VHS) to reserve free space that’s needed in case you need to rebuild data if a disk failure occurs.
  • Do not disable the Snapshot Delete job.
  • Run the FSAnalyze job only if you are using InsightIQ. FSAnalyze creates data for the InsightIQ file system analytics tools and provide details about data properties and space usage with the OneFS file system.

Additional best practices can be found in the white paper, “EMC Isilon OneFS Job Engine.”

In the latest release of OneFS, several enhancements were made to the Job Engine. These enhancements were highlighted in our video, “Key New Features in EMC Isilon OneFS 7.1.” For more information about the enhanced Job Engine, read the white paper, “EMC Isilon OneFS Job Engine.”

EMC Isilon SmartLock: An overview and demonstration

EMC Isilon supports multiple data protection strategies for your cluster environment. Last month, we featured a video about EMC Isilon SyncIQ™, which uses snapshot technology to replicate changed blocks of data. If you want to apply Write Once Read Many (WORM) data protection to files on your cluster, consider EMC Isilon SmartLock™. SmartLock is Isilon’s licensed software-based approach to WORM data protection and retention.

We have two videos to help you become more familiar with SmartLock. The first video, “Data Protection with EMC Isilon SmartLock,” provides an overview about SmartLock features and functionality. The second video, “Technical Demo: EMC Isilon SmartLock,” provides a demonstration of several procedures in the OneFS command-line interface, such as creating SmartLock directories and setting a default retention period.

SmartLock overview

When you license SmartLock for your cluster, you can have a mix of files with normal protection and files with WORM (or SmartLock) protection. With SmartLock, you designate SmartLock directories and select files in those directories to commit to SmartLock status. During the commit process, files are assigned a retention period: a period. During this retention period, files cannot be modified or deleted.

SmartLock operates in either Enterprise or Compliance mode. Compliance mode enables you to meet specific regulatory compliance requirements, such as SEC 17a-4 requirements. If you run SmartLock in Compliance mode, the entire cluster operates in Compliance mode and cannot be reverted to Enterprise mode.

In the following video, EMC Isilon Solutions Architect Russ Stevenson covers these concepts in more detail and answers the following frequently asked questions:

  • What is SmartLock?
  • What are the options for setting up and configuring SmartLock?
  • How does the privileged delete function work?
  • How do I commit a file to SmartLock status?
  • What is SmartLock compliance mode?

SmartLock technical demo

If you’re already familiar with SmartLock and want to learn more about some common commands, the following video offers demonstrations of these procedures:

  • Initial configuration
  • Default retention period
  • File commitment and properties
  • Explicit retention period
  • Retention date override
  • Privileged delete

How to collect files for EMC Isilon Technical Support

Collect Files for EMC Isilon Technical SupportWhen working with EMC Isilon Technical Support to troubleshoot an issue with your cluster, you may be asked to send your cluster’s log and configuration files to an Isilon Support Engineer. To do this, you’ll need to run a process to collect this information. This process creates a single file that contains all of your cluster’s log and configuration information. This file is then automatically uploaded to the Isilon FTP site where the Support Engineer can access it.

To start this process, follow one of these procedures:

  • From the OneFS web administration interface:
    • In OneFS 7.0.x through 7.1, go to Help > Diagnostics and click Start Gather
    • In OneFS 6.0.x through 6.5.x, go to Help > Diagnostics > Gather Info and click Start Gather
  • From the OneFS command-line interface, run the isi_gather_info command

For more information

Watch the video “How to Collect Files for EMC Isilon Technical Support” for a demonstration of these procedures.

This video is based on the popular Knowledgebase (KB) article “How to collect node information, including log files” (log in to the EMC Online Support site to view this article). The KB article provides a written description of these procedures and links to related articles such as “How to upload files to Isilon Technical Support”.

Video Transcript

Hello, I’m Kirsten Gantenbein, a Senior Technical Writer at EMC Isilon.

Log and configuration files can help EMC Isilon Technical Support troubleshoot and resolve issues with your cluster.

In this video, we look at how to collect these files using the Isilon OneFS web administration interface and the command line interface.

First let’s use the OneFS web administration interface.

Log in to any node in your cluster using the root account.

Depending on the version of OneFS you’re running, the next step is different.

On OneFS 7.0 and later, click Help then click Diagnostics.

On OneFS 6.5 and earlier, click Help, point to Diagnostics, and then click Gather Info.

The steps are the same for all versions from this point. We’ll continue this demonstration on OneFS 7.0.

Click Start Gather.

It takes several minutes to gather the log and configuration files.

In the Log section, click Expand to see when each stage of the gather process is complete.

When the gather process is complete, the files are automatically uploaded to the Isilon FTP site.

The Archived Info Manager section contains a list of gathered files, the date they were gathered, and the size of the file.

You can also use the command line to gather log and configuration files.

Open an SSH connection to any node in the cluster and log in using the root account.

Run the isi_gather_info command.

The gather process begins and progress information appears.

As with the web administration interface, the process takes several minutes.

When the gather process is complete, the files are automatically uploaded to the Isilon FTP site.

For a list of additional options, run the isi_gather_info –h command.

For a written description of how to gather log and configuration files, see the following knowledge base article.

If you need assistance with this procedure, contact EMC Isilon Technical Support.

Thanks for watching.
