Hi list,

how can i do a short maintanance like a kernel upgrade on an osd host?
Right now ceph starts to backfill immediatly if i say:
ceph osd out 41
...

Without ceph osd out command all clients hang for the time ceph does not
know that the host was rebootet.

I tried
ceph osd set nodown and ceph osd set noout
but this doesn't result in any difference

Stefan
