Subject: tests: populate /dev/disk/by-partuuid for scsi_debug
X-Git-Tag: v10.2.4~44^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=d205b74e07ab364378afb4fc63cb08814a8a1f4e;p=ceph.git

tests: populate /dev/disk/by-partuuid for scsi_debug

The scsi_debug SCSI devices do not have a symlink in /dev/disk/by-partuuid
because they are filtered out by 60-persistent-storage.rules. That was
worked around by 60-ceph-partuuid-workaround-rules which has been
removed by 9f76b9ff31525eac01f04450d72559ec99927496.

Add create rules targetting this specific case, only for tests since the
problem does not show in real use cases.

Fixes: http://tracker.ceph.com/issues/17100
