Joshua Boniface 103e9fe147 Add restart overrides for ceph-mgr
Needed because ceph-mgr seems to crash frequently under Debian 12 when
adding or removing OSDs. The default settings do not restart it
properly, so this override does.

Joshua Boniface 07d75573d6 Add updated tuning configuration
Uses a much nicer CPU tuning configuration, leveraging systemd's
AllowedCPUs and CPUAffinity options within a set of slices (some
default, some custom).

Configuration is also greatly simplified versus the previous
implementation, simply asking for a number of CPUS for both the system
and OSDs, and calculating everything else that is required.

Also switches (back) to the v2 unified cgroup hierarchy by default as
required by the systemd AllowedCPUs directive.

Joshua Boniface 1d35fec8a8 Remove cpuset configurations
This functionality simply did not work, with Libvirt continuing to dump
its processes into the root cset thus defeating the purpose entirely.

Just remove it, from some very initial testing it isn't worth the
headache.

Joshua Boniface d6cb28b639 Add immutability to PVC subrole
1. Remove the obsolete pvc-vacuum script install.

2. Remove notifies when modifying configs; we do not want to restart the
daemons uncontrolled.

3. Add bootstrap check to package installs so they only happen on
bootstrap.

This ensures this part of the role, on re-runs, will *only* update
configs and not actually touch the running daemon. This makes it safe to
run before a oneshot/update-pvc-daemons.yml playbook run.

Joshua Boniface 87803cb7a2 Remove extraneous splits
The node.hostname should always be short.
2023-09-01 15:42:28 -04:00
Joshua Boniface d24cb8a8ef Unify and standardize inventory_hostname
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Joshua Boniface 6e2d661134 Adjust documentation and behaviour of cpuset
1. Detail the caveats and specific situations and ref the documentation
which will provide more details.

2. Always install the configs, but use /etc/default/ceph-osd-cpuset to
control if the script does anything or not (so, the "osd" cset set is
always active just not set in a special way.

Joshua Boniface 6e48d6fe84 Add Ceph OSD cpuset tuning options
Allows an administrator to set CPU pinning with the cpuset tool for Ceph
OSDs, in situations where CPU contention with VMs or other system tasks
may be negatively affecting OSD performance. This is optional, advanced
tuning and is disabled by default.

Joshua Boniface 13556918d7 Disable any systemd start rate limiting
Because Zookeeper is supremely stupid (see last commit) we want to
disable start limiting. It needs to keep trying forever until it starts.
