Marking exclusion set

Marking exclusion set

  • OneFS marks blocks that are in use by the file system. IntegrityScan, for example, traverses the live file system, marking every block of every LIN in the cluster to proactively detect and resolve any issues with the structure of data in a cluster. The jobs in the marking exclusion set are:

    • Collect
    • IntegrityScan
    • MultiScan

    Jobs may also belong to both the restriping and marking exclusion sets. For example, MultiScan includes both AutoBalance (in the restriping exclusion set) and Collect (in the marking exclusion set).

    Multiple jobs from the same exclusion set will not run simultaneously. For example, Collect and IntegrityScan cannot be run simultaneously because they are both members of the marking exclusion set. Similarly, MediaScan and SetProtectPlus will not run concurrently because they are both part of the restriping exclusion set.
