After upgrading on git + 802cf861352d3c77800488d812009cbbc7184c73.patch, I got one host repeated restart problem: 2/3 OSDs - "osd/ReplicatedPG.cc: 387: FAILED assert(needs_recovery)" after start of repair. After series of restart, on progressed repair %, HEALTH_OK. Are there subject to report more?

There is a regression in librbd in v0.94.4 that can cause VMs to crash.
For now, please refrain from upgrading hypervisor nodes or other librbd
users to v0.94.4.

The problem does not affect server-side daemons (ceph-mon, ceph-osd,
etc.).

Jason's identified the bug and has a fix prepared, but it'll probably take
a few days before we have v0.94.5 out.

Thanks!
