I am considering converting some OSDs to xfs (currently running btrfs)
for stability reasons. I have a couple of ideas for doing this, and
was hoping to get some comments:
Method #1:
1. Check cluster health and make sure data on a specific OSD is
replicated elsewhere.
2. Bring down the OSD
3.
After I run the 'ceph osd out 123' command, is there a specific ceph
command I can poll so I know when it's OK to kill the OSD daemon and
begin the reformat process?
