Guillaume Abrioux 5e5473028b switch-to-containers: only chown corresponding files
When collocating daemons, if we chown all files under `/var/lib/ceph` it
can cause issues for the collocated daemons that wouldn't have been
migrated yet.

This commit makes the playbook chown only the files corresponding to the
daemon being migrated.

Dimitri Savineau 2436044369 switch_to_containers: set GUID on lockbox part
The ceph lockbox partition (part number 5) used with non lvm scenarios
and in non containerized deployment don't have a valid PARTUUID.
The value is set to 00000000-0000-0000-0000-000000000000 for each OSD
devices.

$ blkid -t PARTLABEL="ceph lockbox" -o value -s PARTUUID
00000000-0000-0000-0000-000000000000
00000000-0000-0000-0000-000000000000
00000000-0000-0000-0000-000000000000
00000000-0000-0000-0000-000000000000
00000000-0000-0000-0000-000000000000

When switching to containerized deployment we manually mount the lockbox
partition by using the PARTUUID.
Unfortunately because we have most of the time multiple OSD on the same
node we can't have the right symlink in /dev/disk/by-partuuid because it
will point to only one partition.

/dev/disk/by-partuuid/00000000-0000-0000-0000-000000000000 -> ../../sdb5

After the switch_to_containers playbook then only one OSD will restart
correctly and the other will try to access to the wrong device causing
error like 'xxxx is still in use'.

When deploying with containers and dmcrypt OSDs we force a PARTUUID
value during the ceph-disk prepare task.

Dimitri Savineau b08ac9cd44 switch_to_containers: fix umount ceph partitions
When a container is already running on a non containerized node then the
umount ceph partition task is skipped.
This is due to the container ps command which always returns 0 even if
the filter matches nothing.

We should run the umount task when:
1/ the container command is failing (not installed) : rc != 0
2/ the container command reports running ceph-osd containers : rc == 0

Also we should not fail on the ceph directory listing.

Dimitri Savineau 2d40e3923f switch_to_containers: umount osd lockbox partition
When switching from a baremetal deployment to a containerized deployment
we only umount the OSD data partition.
If the OSD is encrypted (dmcrypt: true) then there's an additional
partition (part number 5) used for the lockbox and mount in the
/var/lib/ceph/osd-lockbox/ directory.
Because this partition isn't umount then the containerized OSD aren't
able to start. The partition is still mount by the system and can't be
remount from the container.

Kevin Jones b3abe23493 Set proper ownership command performance improvement
By changing the set ownership command from using the file module in combination with a with_items loop to a raw chown command, we can achieve a 98% performance increase here.

On a ceph cluster with a significant amount of directories and files in /var/lib/ceph, the file module has to run checks on ownership of all those directories and files to determine whether a change is needed.

In this case, we just want to explicitly set the ownership of all these directories and files to the ceph_uid

Added context note to all set proper ownership tasks
