For complete information, see the. Multiscan runs only if there is any unbalanced diskpool or if it determines that a drive has been down for a long enough period that running the Collect process to reclaim free space is worthwhile. The FlexProtect job is responsible for maintaining the appropriate protection level of data across the cluster. Research science group expanding capacity, Press J to jump to the feed. When such file or inode is found, the job opens the LIN and repairs it and the corresponding data blocks using the restripe process. FlexProtectLin is run by default when there is a copy of file system metadata available on solid state drive (SSD) storage. The prior repair phases can miss protection group and metatree transfers. Run automatically after a drive or node removal or failure, FlexProtect locates any unprotected files on the cluster and repairs them as quickly as possible. Creates a list of changes between two snapshots with matching root paths. This is 'Phase 1' of the FSAnalyze job but sometimes this is not the part that takes the longest since this phase is multithreaded and the work is split between the nodes in the cluster. This ensures that no single node limits the speed of the rebuild process. You can run any job manually, and you can create a schedule for most jobs according to your workflow. The following CLI syntax will kick of a manual job run: The FlexProtect jobs progress can be tracked via a CLI command as follows: Upon completion, the FlexProtect job report, detailing all six stages, can be viewed by using the following CLI command with the job ID as the argument: While a FlexProtect job is running, the following command will detail which LINs the job engine workers are currently accessing: Using the isi get -L command, a LIN address can be translated to show the actual file name and its path. After a component failure, lost data is restored on healthy components by the FlexProtect proprietary system. Yes, disk queues are quite high for a few drives on the node which has the drive that are smartfailing. Scan for, and unlink, expired files in compliance stores. The WDL enables FlexProtect to perform fast drive scanning of inodes because the inode contents are sufficient to determine need for restripe. Isilon FlexProtect protects data in the cluster based on the configured protection policy, quickly rebuilding failed disks, harnessing free storage space across the entire cluster to further prevent data loss, and monitoring and preemptively migrating data off of at-risk components. FlexProtect would pause all the jobs except youve job engine tweaked.

Isilon cluster An Isilon cluster consists of three or more hardware nodes, up to 144. If AutoBalance is enabled, the system runs it automatically when a device joins (or rejoins) the cluster. The parity overhead for N + M protection depends on the file size and the number of nodes in the cluster. But if you are on a modern OneFS, this usually occurs when you have two jobs that need to run that are in the same exclusion set. Runs automatically on group changes, including storage changes. Other jobs will automatically be paused and will not resume until FlexProtect has completed and the cluster is healthy again. About Script Health Isilon Check . AutoBalance restores the balance of free blocks in the cluster. If an inode needs repair, the job engine sets the LINs needs repair flag for use in the next phase. The job engine then executes the job with the lowest (integer) priority. 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. So I don't know if its really that much better and faster as they claim. The regular version of FlexProtect has the following phases: Be aware that prior to OneFS 8.2, FlexProtect is the only job allowed to run if a cluster is in degraded mode, such as when a drive has failed, for example. As such, AutoBalance runs if a clusters nodes have a greater than 5% imbalance in capacity utilization. A FlexProtect job will start a priority of 1, which will cause any other running jobs to pause until the SmarFail process completes. The WDL keeps a list of the drives in use by a particular file, and are stored as an attribute within an inode and are thus protected by mirroring. Balances free space in a cluster. Click Start.
