Title:
ceph-volume: block device permissions sometimes not set on initial
activate call
Status in ceph package in Ubuntu:
In Progress
Bug description:
When using bluestore or filestore with a separate journal device, we
often see that the ceph-osd daemon crashes on activation with a
'permission denied' error on the link to the block device supporting
the particular component of the OSD (bluestore block/wal/db or journal
device for filestore).
chown -R ceph:ceph /dev/dm-X fixes the issue and the osd can then be
started; I've also not seen this issue occur during a normal reboot
(as the permissions are re-asserted by ceph-volume as OSD's are
started up).
Hunch is something udev-y is racing with ceph-volume on the initial
activiate call but not tracked it down yet.
