You could pause FlexProtect job and run other job by removing job engine from "Degraded" mode, but at this stage again I would ask you to check with support . When you create a local user, OneFS automatically creates a home directory for the user. Uses a template file or directory as the basis for permissions to set on a target file or directory. Scans a directory for redundant data blocks and deduplicates all redundant data stored in the directory. This job runs on a regularly scheduled basis, and can also be started by the system when a change is made (for example, creating a compatibility that merges node pools). For example, it ensures that a file which is configured to be protected at +2n, is actually protected at that level. setting to determine whether to run FlexProtect or FlexProtectLin. It seems like how Flexprotect work is a big secret. You can specify the protection of a file or directory by setting its requested protection. The following CLI syntax will kick of a manual job run: The Multiscan jobs progress can be tracked via a CLI command as follows: The LIN (logical inode) statistics above include both files and directories. This phase ensures that all LINs were repaired by the previous phases as expected. Can also be run manually. 2, health checks no longer require you to create new controllers like in the example. 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. Run automatically after a drive or node removal or failure, FlexProtect locates any unprotected files on the cluster, and repairs them as rapidly as possible. If concerned, verify that the stated total LIN count is roughly in line with the file count for the clusters dataset. Flexprotect - what are the phases and which take the most time? I guess it then will have to rebuild all the data that was on the disk.

Scan the file system after a device failure to ensure that all files remain protected. A flex protect job can follow these inode trails, locate the ones that point to defunct blocks or lack the proper number of blocks, then it can make sure the required number of copies of each block are present and valid. As such, the primary purpose of FlexProtect is to repair nodes and drives which need to be removed from the cluster. (Stalled drives are bad, and can cause cluster problems. The WDL is primarily used by FlexProtect to determine whether an inode references a degraded node or drive. FlexProtect may have already repaired the destination of a transfer, but not the source. If a cluster component fails, data stored on the failed component is available on another component. An Isilon customer currently has an 8-node cluster of older X-Series nodes. When you create a local user, OneFS automatically creates a home directory for the user.
