Could you clarify if you are seeing faults as reported by the cluster (FSAnalyze job) and/or as reported by InsightIQ? Each node has two layers:  the initiator layer and the participant layer. When a node receives a file, it breaks it down into a stripe unit or multiple stripe units. Engine, OneFS runs a subset of these jobs automatically, as needed, to ensure file and data integrity, check for and mitigate All new nodes must be racked, connected on the InfiniBand network and powered on. A stripe unit is 128KB in size. However, you can run any job manually or schedule any job to run periodically OneFS includes system maintenance jobs that run to ensure that your Isilon cluster performs at peak health. Priority determines which Isilon job get priority when multiple jobs are running. Available only if you activate a SmartQuotas license. The target directory must always be subordinate to the. Try to run FlexProtect in stead. By default, system jobs are categorized as either manual or scheduled. you can provide output for the job to see why it failed # isi job status # isi job reports view --id=1348 Example: isi job reports view --id=1345. For deep analysis you'd want to review the /var/log/isi_job_d.log file (or anything of the archived logs *.gz). ( Log Out /  This allows for simultaneous failure of two drives, or one entire node. The Job Engine assigns a priority value between 1 and 10 to every job, with 1 being the most important and Prior to OneFS 7.1.1.x only one Isilon job was allowed to run at any time, and highest priority job would run and other would wait in queue.

access, migrate data, integrate with other applications, and monitor an EMC Isilon cluster. If, you use the File System Analytics feature, you must also enable the NFS service, HTTPS port. Trying to copy the remain data off the soft_failed drive to the other drives in the cluster? This guide describes how the web administration interface provides access to cluster configuration, management, and monitoring functionality. Change ), You are commenting using your Facebook account. After completing a task, each node reports task status to the job coordinator. In +2:1, which is the default protection level used out-of-the-box, a single stripe unit is written to two disks per node, in addition to using two FEC units per stripe. I guess it then will have to rebuild all the data that was on the disk. Yes, disk queues are quite high for a few drives on the node which has the drive that are smartfailing. Depending on the size of your data set, this process can last for an extended period. Will it kick off a autobalance job to restripe data from the other drives onto the new drive? In this way, no one node is overburdened, and system resources remain available for other administrator and system I/O activities not originated from the Job Engine. functions include monitoring and optimizing performance, detecting and mitigating drive and node failures, and freeing up available space. That is the amount of data that Isilon will try to write to each disk drive, using a block size of 8KB. The Job Engine runs system maintenance jobs in the background and prevents jobs within the same classification (exclusion set) from running simultaneously. For other jobs, for example, Dedupe, you can use Job Engine to start them You can also choose to mirror data from 2x to 8x. Frees up space that is associated with shadow stores. At a +1 protection level, you will have one Forward Error Correction unit per stripe unit as seen here: Earlier I mentioned +2:1 and +3:1 protection levels. Available only if you activate a SmartDedupe license. Scans a directory for redundant data blocks and reports an estimate of the amount of space that could be saved by deduplicating the directory. Balances free space in a cluster, and is most efficient in clusters when file system metadata is stored on solid state drives (SSDs). Through the Job Engine, OneFS runs a subset of these jobs automatically, as needed, to ensure file and data integrity, check for and mitigate drive and node failures, and optimize free space. Runs only if a SmartPools license is not active. Protects shadow stores that are referenced by a logical i-node (LIN) with a higher level of protection.

cluster I/O activity and other system administration tasks. By default, system Job operation. * Available only if you activate an additional license. At this point then of course ignore everything I mentioned above as whether or not the InsightIQ server can mount the fsa directory on the monitored cluster has no impact on the FSAnalyze job which runs regardless. 10 being the least important. OneFS contains a library of system jobs that run in the background to help maintain your Isilon cluster.

If at any point phase 2 fails, by default it needs to start all over. jobs are categorized as either manual or scheduled.

Next week, I will wrap up this blog series by reviewing the advanced features available with Isilon.

jobs are categorized as either manual or scheduled. You cannot change the exclusion set parameter for a job type. It seems like how Flexprotect work is a big secret. Powered by the

Note that MultiScan is a member of both the restripe and mark exclusion sets. you can provide output for the job  to see why it failed, # isi job reports view --id=1348  , FSAnalyze[1345] phase 2 (2014-07-22T22:40:53), ---------------------------------------------, Elapsed time:                       20 seconds, CPU usage:                         max 53% (dev 6), min 0% (dev 7), avg 11%, Virtual memory size:               max 211308K (dev 6), min 135532K (dev 7), avg 155329K, Resident memory size:              max 91680K (dev 6), min 17636K (dev 7), avg 35705K, Read:                              327 ops, 3379712 bytes (3.2M), Write:                             26523 ops, 216485376 bytes (206.5M), FSAnalyze[1345] phase 1 (2014-07-22T22:40:33), Elapsed time:                     2421 seconds, CPU usage:                         max 61% (dev 6), min 2% (dev 6), avg 31%, Virtual memory size:               max 202988K (dev 6), min 133996K (dev 6), avg 144263K, Resident memory size:              max 83588K (dev 6), min 15964K (dev 8), avg 23186K, Read:                              74181 ops, 539489280 bytes (514.5M), Write:                             43626 ops, 353920512 bytes (337.5M). A job phase must be completed in entirety before the job can progress to the next phase. Other job parameters determine whether jobs are enabled, their performance impact, and schedule. For other jobs, for example, Dedupe, you can use Job Engine to start them manually or schedule them to run automatically at regular intervals. The Isilon scale-out NAS storage platform combines modular hardware with unified software to harness unstructured data. You can generate reports for system jobs and view statistics to better determine the amounts of system resources being used.

Join the new nodes to the cluster.

I have tried to search documents to get answers, but can't find anything. The second phase is what is probably being alluded to by future changes. As a result, our InsightIQ is very well utilized. When a job starts, the Job Engine distributes job segments—phases and tasks—across the nodes of your cluster. For, monitored clusters running an earlier version of OneFS, you must enable HTTPS port 9443. The node acting as job coordinator saves this task status information to a checkpoint file. While there is a device failure on a cluster, only the FlexProtect (or FlexProtectLin) job is allowed to run. Press J to jump to the feed. FlexProtectLin Yes MEDIUM. Shadow stores are hidden files that are referenced by cloned and deduplicated files. functions include monitoring and optimizing performance, detecting and mitigating drive and node failures, and freeing up They have something called a soft_failed drive, at least that's what I can see in the logs. ... For more information, see the Isilon Supportability and Compatibility Guide. The Job Engine is also sensitive to job priority, and can run up to three jobs, of any priority, simultaneously.
