Joshua Boniface f2a9764f52 Further optimize ownership agent output 2022-05-31 22:38:05 -04:00
Joshua Boniface b90717e25a Make ownership check consistent with cmk-agent 2.1
The new CheckMK agent uses UID 998 (dynamic) for itself. This causes
ownership problems with the old logic of this check. Move instead to a
range, where the UIDs from 200-599 are reserved for administrators, and
check for this range explicitly. Also eliminates the exceptions for ceph
and 2000 from previous iterations.

Use an updated plugin from BLSE that uses needrestart instead of manual
parsing of these elements.

Joshua Boniface bea79b5102 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 414678f683 Fix a few more extraneous splits
Just use this_node if applicable, or the raw node.hostname.
2021-11-11 17:35:42 -05:00
Joshua Boniface b24e539252 Remove extraneous splits
The node.hostname should always be short.
2021-11-11 17:31:56 -05:00
Joshua Boniface 243c910d6d 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 fed71d7add Add option for setting CPU governor
Allows the administrator to set a CPU frequency governor if they need
to, though the default of ondemand is usually sufficient.

Joshua Boniface 3de777a036 Disable unified cgroup heirarchy on kernel cmdline
This is required on Debian 11 to use the cset tool, since the newer
systemd implementation of a unified cgroup hierarchy is not compatible
with the cset tool.

Joshua Boniface 5797535997 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 8ac2a5ea0c Adjust default ceph.conf parameters
1. Remove an explicit OSD journal size, especially such a small one (no
clue why I ever added that...)

2. Add max scrubs, disable scrub during recovery, and set scrub sleep.

3. Add max backfills, tune recovery sleep to 0 to prioritize recovery.

Joshua Boniface 732bfe732c 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.
