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.
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.
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:
When 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
One of the goals of this blog is to share the most useful EMC Isilon support-related content that we have to offer. In this post, we’re highlighting 20 of the most viewed knowledgebase (KB) articles and product documents from the month of December.
We hope these documents will help you to quickly find an answer to a common question or resolve an issue.
