Prepopulating a FlexCache volume

You can prepopulate a FlexCache volume to reduce the time it takes to access cached data.

  • You must be a cluster administrator at the advanced privilege level
  • The paths you pass for prepopulation must be valid or the prepopulate operation fails.
  • Prepopulate reads files only and crawls through directories
  • The is-recursion flag applies to the entire list of directories passed to prepopulate
  1. Prepopulate a FlexCache volume: volume flexcache prepopulate -cache-vserver vserver_name -cache-volume -path-list path_list -is-recursion true|false

    This example includes a single directory path for prepopulation:

    cluster1::*> flexcache prepopulate start -cache-vserver vs2 -cache-volume fg_cachevol_1 -path-list /dir1
      (volume flexcache prepopulate start)
    [JobId 207]: FlexCache prepopulate job queued.

    This example includes a list of several paths for prepopulation:

    cluster1::*> flexcache prepopulate start -cache-vserver vs2 -cache-volume fg_cachevol_1 -path-list /dir1,/dir2,/dir3,/dir4
      (volume flexcache prepopulate start)
    [JobId 208]: FlexCache prepopulate job queued.

  2. Display the number of files read: job show -id job_ID -ins
