Since a couple of days we're suddenly experiencing random segfaults leading to
failing OSDs. We didn't update any packages on our ceph servers, they ran
stable until these segfaults.
Sometimes the OSDs recover by themselves, sometimes a whole host goes down and
leaves a degraded cluster. The description in [2] sounds exactly like our issue
([1] is a duplicate of [2]). I'll spare you the details since the upstream bug
has lots of information.
There seems to be a backport [3] for Luminous, but it's still in progress
although the change has been reviewed. I just wanted to raise awareness for
this issue since it impacts our production cluster that ran stable for months
and we'd appreciate it if the updated packages would be available soon to fix
this issue.
Please let me know if any further information is needed.
