Dimitri Savineau 070db68ffd ceph-handler: don't restart all OSDs with limit
When using the ansible --limit option on one or few OSD nodes and if the
handler is triggered then we will restart the OSD service on all OSDs
nodes instead of the hosts limited by the limit value.
Even if the play is limited by the --limit value we are using all OSD
nodes from the OSD group.

  with_items: '{{ groups[osd_group_name] }}'

Instead we should iterate only on the nodes present in both OSD group and
limit list.

Dimitri Savineau 28009496f6 ceph-handler: Fix osd restart condition
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.

Giulio Fidente e0e9fa47df Look for additional names when checking ceph-nfs container status
Ganesha cannot be operated active/active, in those deployments
where it is managed by pacemaker the container name can be
different than the default.

This change uses "ceph_nfs_service_suffix" where previously
missing to ensure tasks will work with customized names.

Dimitri Savineau bedc0ab69d ceph-osd: use OSD id with systemd ceph-disk
When using containerized deployment we have to create the systemd
service unit based on a template.
The current implementation with ceph-disk is using the device name
as paramater to the systemd service and for the container name too.

$ systemctl start ceph-osd@sdb
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE                        NAMES
065530d0a27f ceph/daemon:latest-luminous  ceph-osd-strg0-sdb

This is the only scenario (compared to non containerized or
ceph-volume based deployment) that isn't using the OSD id.

$ systemctl start ceph-osd@0
$ docker ps --filter 'name=ceph-osd-*'
CONTAINER ID IMAGE                        NAMES
d34552ec157e ceph/daemon:latest-luminous  ceph-osd-0

Also if the device mapping doesn't persist to system reboot (ie sdb
might be remapped to sde) then the OSD service won't come back after
the reboot.

This patch allows to use the OSD id with the ceph-osd systemd service
but requires to activate the OSD manually with ceph-disk first in
order to affect the ID to that OSD.

Dimitri Savineau 94cdef2757 ceph-handler: Fix rgw socket in restart script
If the SOCKET 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 SOCKET value isn't defined.
  - 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_EXEC variable in order to execute the
command.

$ test 'wget http://192.168.100.11:8080'
$ echo $?
0

Dimitri Savineau 9cc5d1e903 ceph-handler: Fix radosgw_address default value
The rgw restart script set the RGW_IP variable depending on ansible
variables:
  - radosgw_address
  - radosgw_address_block
  - radosgw_interface

Those variables have default values defined in ceph-defaults role:

radosgw_interface: interface
radosgw_address: 0.0.0.0
radosgw_address_block: subnet

But in the rgw restart script we always use the radosgw_address value
instead of the radosgw_interface when defined because we aren't testing
the right default value.
As a consequence, the RGW_IP variable will be set to 0.0.0.0 even if
the ip address associated to the radosgw_interface variable is set
correctly. This causes the check_rest function to fail.

Dimitri Savineau 2b492e3de1 ceph-handler: Fix OSD restart script
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
46c7240d71f3 ceph-daemon:latest ceph-osd-strg0-sdaa
877985ec3aca ceph-daemon:latest ceph-osd-strg0-sdab
$ docker container ls -q -f "name=sda"
958121a7cc7d
46c7240d71f3
877985ec3aca

$ docker container ls
CONTAINER ID IMAGE              NAMES
2db399b3ee85 ceph-daemon:latest ceph-osd-5
099dc13f08f1 ceph-daemon:latest ceph-osd-13
5d0c2fe8f121 ceph-daemon:latest ceph-osd-17
d6c7b89db1d1 ceph-daemon:latest ceph-osd-1
$ docker container ls -q -f "name=ceph-osd-1"
099dc13f08f1
5d0c2fe8f121
d6c7b89db1d1

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

Finally removing the get_container_osd_id function because it's not
used in the script at all.

Dimitri Savineau 95f3908e44 ceph-handler: replace fuser by /proc/net/unix
We're using fuser command to see if a process is using a ceph unix
socket file. But the fuser command runs through every PID present in
/proc/<PID> to see if one of them is using the file.
On a system running thousands processes, the fuser command can take
a long time to finish.

Dimitri Savineau bbb8ca6643 mon/rgw: use last ipv6 address
When using monitor_address_block or radosgw_address_block variables
to configure the mon/rgw address we're getting the first ip address
from the ansible facts present in that cidr.
When there's VIP on that network the first filter could return the
wrong value.
This seems to affect only IPv6 setup because the VIP addresses are
added to the ansible facts at the beginning of the list. This is the
opposite (at the end) when using IPv4.
This causes the mon/rgw processes to bind on the VIP address.
