Joshua Boniface 00005c62d6 Alter format of Debian version in MOTD 2023-01-17 10:51:40 -05:00
Joshua Boniface 7b51fe0d00 Adjust name of bootstrap trigger variable
The PVC bootstrap framework overrides this variable and wreaks havoc on
it. Instead adjust our side so that it looks for do_bootstrap instead.

Joshua Boniface 408f5afaee Replace per-user htoprc with system-wide config
Also update to newer htoprc layout from BLSE.

Joshua Boniface 3c1c97dbf5 Ensure CPU tuning is only applied on Debian 11+ 2022-11-15 16:21:48 -05:00
Joshua Boniface c5ec0f4f62 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 7d329708bc 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 fac388ed79 Update MOTD automatically on boot
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.

Joshua Boniface 78342cf4a4 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 503a2e6c0b Remove pvc-flush references
This service causes more problems than it solves usually, so it is being
removed in the next PVC version.

Joshua Boniface 87ae5a12e9 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 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 e4e084cc5b Fix name of task 2021-11-15 14:46:44 -05:00
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.

The node.hostname should always be short.

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.
