The ceph status command returns a lot of information stored in variables
and/or facts which could consume resources for nothing.
When checking the quorum status, we're only using the quorum_names
structure in the ceph status output.
To optimize this, we could use the ceph quorum_status command which contains
the same needed information.
This command returns less information.
$ ceph status -f json | wc -c

$ ceph quorum_status -f json | wc -c

When rgw and osd are collocated, the current workflow prevents from
scaling out the radosgw_num_instances parameter when rerunning the
playbook in baremetal deployments.
When ceph-osd notifies handlers, it means rgw handlers are triggered
too. The issue with this is that they are triggered before the role
ceph-rgw is run.
In the case a scaleout operation is expected on `radosgw_num_instances`
it causes an issue because keyrings haven't been created yet so the new
instances won't start.

In non containerized deployment we check if the service is running
via the socket file presence.
This is done via the xxx_socket_stat variable that check the file
socket in the /var/run/ceph/ directory.
In some scenarios, we could have the socket file still present in
that directory but not used by any process.
That's why we have the xxx_stat variable which clean those leftovers.
The problem here is that we're set the variable for the handlers status
(like handler_mon_status) based on xxx_socket_stat instead of xxx_stat.
That means we will trigger the handlers if there's an old socket file
present on the system without any process associated.

In containerized deployment, the restart OSD handler couldn't be
triggered in most ansible execution.
This is due to the usage of run_once + a condition on the inventory
hostname and the last filter.
The run_once is triggered first so ansible will pick a node in the
osd group to execute the restart task. But if this node isn't the
last one in the osd group then the task is ignored. There's more
probability that the task will be ignored than executed.

Since Mimic the radosgw socket has two extra fields in the socket
name (before the .asok suffix): <pid>.<ctid>
Before:
/var/run/ceph/ceph-client.rgw.cephaio-1.asok
After:
/var/run/ceph/ceph-client.rgw.cephaio-1.16913.23928832.asok
The radosgw restart script doesn't handle this and could fail during
an upgrade.
If the SOCKETS variable isn't defined in the script then the test
command won't fail because the return code is 0
$ test -S
$ echo $?
0
There multiple issues in that script:
- The default SOCKETS value isn't defined due to a typo
SOCKET vs SOCKETS.
- Because the socket name uses the pid then we need to check the
socket name after the service restart.
- After restarting the radosgw service we need to wait few seconds
otherwise the socket won't be created.
- Update the wget parameters because the command is doing a loop.
We now use the same option than curl.
- The check_rest function doesn't test the radosgw at all due to
a wrong test command (test against a string) and always returns 0.
This needs to use the DOCKER_EXECS variable in order to execute the
command.
$ test 'wget http://192.168.100.11:8080'
$ echo $?
0
Also remove the test based on the ansible_fqdn because we only use
the ansible_hostname + rgw instance name.
Finally group all for loop into a single one.

There's two big issues with the current OSD restart script.
1/ We try to test if the ceph osd daemon socket exists but we use a
wildcard for the socket name : /var/run/ceph/*.asok.
This fails because we usually have multiple ceph osd sockets (or
other ceph daemon collocated) present in /var/run/ceph directory.
Currently the test fails with:
bash: line xxx: [: too many arguments
But it doesn't stop the script execution.
Instead we can specify the full ceph osd socket name because we
already know the OSD id.
2/ The container filter pattern is wrong and could matches multiple
containers resulting the script to fail.
We use the filter with two different patterns. One is with the device
name (sda, sdb, ..) and the other one is with the OSD id (ceph-osd-0,
ceph-osd-15, ..).
In both case we could match more than needed.
$ docker container ls
CONTAINER ID IMAGE NAMES
958121a7cc7d ceph-daemon:latest ceph-osd-strg0-sda
589a982d43b5 ceph-daemon:latest ceph-osd-strg0-sdb

Adding an extra '$' character at the end of the pattern solves the
problem.

used in the script at all.
