Re: remove require_jewel_osds flag after upgrade to kraken

The flag is fine, it's just to ensure that OSDs from a release before Jewel can't be added to the cluster:

See http://ceph.com/geen-categorie/v10-2-4-jewel-released/ under "Upgrading from hammer"

hi,

is it possible to remove the require_jewel_osds flag after upgrade to kraken?

$ ceph osd stat
     osdmap e29021: 40 osds: 40 up, 40 in
            flags sortbitwise,require_jewel_osds,require_kraken_osds

it seems that ceph osd unset does not support require_jewel_osds

$ ceph osd unset require_jewel_osds
Invalid command:  require_jewel_osds not in
full|pause|noup|nodown|noout|noin|nobackfill|norebalance|norecover|noscrub|nodeep-scrub|notieragent|sortbitwise
osd unset full|pause|noup|nodown|noout|noin|nobackfill|norebalance|norecover|noscrub|nodeep-scrub|notieragent|sortbitwise
:  unset <key>
Error EINVAL: invalid command

is there any way to remove it?
if not, is it ok to leave the flag there?

thanks
fous
