      believe that at the moment you'll only be able to have that flag
      set on a pool at creation time, if 'osd pool default flag
      hashpspool = true' on your conf.
      

    I just updated my config like this:

    
    [osd]

      osd journal size = 100

      filestore xattr use omap = true

      auth cluster required = cephx

      auth service required = cephx

      auth client required = cephx

      osd min pg log entries = 1000

      osd max pg log entries = 3000

      osd pool default flag hashpspool = true

      cephx require signatures = true

    
    Then I created a new pool using "ceph osd pool create test 8" but
    the flag is not set:

    
    pool 26 'test' rep size 2 min_size 1 crush_ruleset 0 object_hash
    rjenkins pg_num 8 pgp_num 8 last_change 434 owner 0

    
      Also found issue #5614 [1], which hasn't seen any work as far as I
      can tell, that would allow what you're after.
      

    Ok, that's bad news. I just searched for a method to copy a complete
    pool and found this issue
    
    http://tracker.ceph.com/issues/2666
    It's in state resolved, but there's no command to copy a pool in the
    latest command line utils? So I wonder what's the best/ easiest way
    to copy all objects from one pool to another (I'll make sure there's
    no write activity on source while copy is in progress).
