def crush(pg):
all_osds = ['osd.0', 'osd.1', 'osd.2', ...]
result = []
# size is the number of copies; primary+replicas
while len(result) size:
-- *r = hash(pg)*
chosen = all_osds[ r %
When you reformat the drive, it generates a new UUID so to Ceph it is as if
it was a brand new drive. This does seem heavy handed, but ceph was
designed for things to fail and it is not unusual to do things this way.
Ceph is not RAID so you usually have to do some unthinking.
You could probably

(I started with BTRFS, then started again from scratch with XFS

of some issues, now with further
