Hello,
We are currently experiencing an unstable cluster on a backup cluster,
we believe it is due to the latest Cephversion 9.2.1
(752b6a3020c3de74e07d2a8b4c5e48dab5a6b6fd). OSDs keep on crashing,
segfaulting, which eventually leads some of them to be down, or leave
the cluster on strange scenarios like having unfound objects.

Our nodes run Ubuntu 14.04.4 LTS, and two of them Ceph version 9.2.0

version 9.2.1 (752b6a3020c3de74e07d2a8b4c5e48dab5a6b6fd). Only on
v.9.2.1. osds keep on segfaulting. On some of them we see:

http://tracker.ceph.com/issues/15628
Here is the log of one of the down OSDs: http://pastebin.com/dcHKrE8f
Now we would like to downgrade to version 9.2.0 all nodes, since we keep
on having osds down and sometimes OSDs with corrupted metadata. However,
it looks like it is not possible to downgrade a Ceph version?
Besides that, we also have "wrong node!" messages on most of our osd
logs (on both nodes with v9.2.1 and v9.2.0). We don't know if it is
related, or if we should also have a look at that.

Our goal is to make downgrades within a stable series possible, but we
have not tested them for infernalis.
There was one fix in the auth code that may affect this. I pushed a
branch that backports it to infernalis and pushed a wip-auth-infernalis
branch. The packages should show up on gitbuilder.ceph.com in an hour or
so. Can you give those a try?
http://gitbuilder.ceph.com/ceph-deb-trusty-x86_64-basic/ref/wip-auth-infernalis
We haven't seen this crash at all in any of our testing. :(

These are harmless--they're just there because OSDs are restarting and
reusing some of the same ports.
