Joshua Boniface 30ddeb0fee Update MOTD automatically on boot 
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.

Joshua Boniface 86026de8ef Adjust colour scheme of MOTD 2023-09-01 15:42:29 -04:00
Joshua Boniface 8e1d005d43 Obtain more information for MOTD header 
Add model and serial numbers to the vendor, and put this on its own
line. Also use BASH for proper syntax formatting. Reformat the header to
be a more compact format.

Joshua Boniface be091f66d4 Remove pvc-flush references 
This service causes more problems than it solves usually, so it is being

Joshua Boniface 6cf8948107 Add Ceph support for single-node clusters 
Ensures that the pool default size/min size is set to something
reasonable for a single node (effective RAID-1) and replace teh default
CRUSH replicate_rule set for this situation with one choosing OSD
instead of host as the default.

Joshua Boniface e8fe165e00 Further optimize ownership agent output 2023-09-01 15:42:28 -04:00
Joshua Boniface cbea6e284c 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.

Joshua Boniface d47d320bb3 Replace freshness and kernel_version checks 
Use an updated plugin from BLSE that uses needrestart instead of manual
parsing of these elements.

Joshua Boniface aa6b4ac3dc Make locale generation universal 
Don't rely on a notify/handler, just do it every time in the base role.

Joshua Boniface a87745d640 Fix name of task 2023-09-01 15:42:28 -04:00
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 77be96bf6f Fix a few more splits 2023-09-01 15:42:28 -04:00
Joshua Boniface 95b47f8b09 Fix a few more extraneous splits 
Just use this_node if applicable, or the raw node.hostname.
 2023-09-01 15:42:28 -04:00
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 056c325486 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 55ec177919 Ignore errors restarting libvirtd

Joshua Boniface b814ec60f6 Add resolv.conf customization 2023-09-01 15:42:27 -04:00
Joshua Boniface ddecb94348 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.
