Adding two fixed Ceph monitors for controllers when deploying an
AIO-DX to improve HA.
Includes:
- Creates a new shell script to manage the fixed monitors
- Creates a new patch to include the mon_data parameter in
the mon.pp puppet manifest.
- Creates the ceph-storage-network script that is used by the
storage-networking SM service to stop Ceph services in case
of a network outage.
- Alters the script used by the ceph-mds pmon file to
ceph-init-wrapper.
- Adjusts the ceph-init-wrapper to accept commands from pmon service.
- Adjusts the ceph-init-wrapper to accept the forcestop command.
- Stopping Ceph services using ceph-init-wrapper, it is checked
if the pid exists before trying.
- Stopping ceph-mon service using ceph-init-wrapper,
the ceph-mds is stopped right before to force a re-peering.
- Starting ceph-mon service using ceph-init-wrapper,
the ceph-mds is stopped right before to force a re-peering.
- Starting ceph-mds, it is checked if the ceph-mon is operational.
- The forcestop command uses a TERM signal first before
attempting a KILL signal after 5 seconds.
Test Plan:
PASS: Fresh install AIO-DX and check 3 Ceph monitors are running.
PASS: Fresh install all other setups and check if Ceph is working as
expected.
PASS: Reboots the standby controller and check if Ceph is still
running.
PASS: Reboots the active controller. Ceph will stop responding, but
it will recover after both controllers are running.
PASS: Verify Ceph is working after a DOR test with PODs writting
to the cephfs and rbd pools.
PASS: Verify Ceph is resilient to switch reboots
