Bug Description

MOS 8.0 and its maintenance updates are using an older version of librbd1 and python-rbd

These older packages cause nova-compute to segfault in certain situations. This issue has been observed in the RedHat ecosystem, but we have a customer reporting what appears to be the same issue in MOS 8.0

The MOS versions of these packages:
librbd1 0.94.5-0u~u14.04+mos3
python-rbd 0.94.5-0u~u14.04+mos3

This issue was addressed in version:

Changed in mos:
importance: Undecided → High
assignee: nobody → MOS Maintenance (mos-maintenance)
milestone: none → 8.0-mu-5
status: New → Confirmed

The MOS Ceph team is strongly against patching Ceph in MOS 8.0 with these patches, which presumably fix the issue:

Because there is no testing framework for this.
They insist on updating Ceph as a whole, the original message from ~asheplyakov:
tl;dr version: please use packages from
deb hammer-trusty main
*and* upgrade playbooks from
*BIG RED WARNING*: a plain "apt-get update && apt-get upgrade" might easily break the cluster, please use the upgrade playbooks, and do check things with a test cluster first

I'm closing this as Won't Fix for the mentioned reason. Please contact MOS Ceph guys for details on how to upgrade Ceph.
