Joshua Boniface 84a3f7afa0 Add edac-utils to packages 2023-09-01 15:42:29 -04:00
Joshua Boniface 612045b8b3 Restore original rsyslog-rotate script 
Direct call doesn't work because of how arguments are passed to
postrotate.

Joshua Boniface 5cd9566163 Explicitly use systemctl in logrotate 
For some reason (Debian bug?) the default rsyslog-rotate script was not
properly rotating rsyslog logfiles. Instead, explicitly call systemctl
kill -s HUP for this, using a full path.

Joshua Boniface 561ecb5c61 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 a79961605a Replace per-user htoprc with system-wide config 
Also update to newer htoprc layout from BLSE.

Joshua Boniface 5a48ec4d79 Ensure CPU tuning is only applied on Debian 11+ 2023-09-01 15:42:29 -04:00
Joshua Boniface 6bf827ca13 Adjust readme texts 2023-09-01 15:42:29 -04:00
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 fa4f1cff0f Adjust variable used for migrate selector 2023-09-01 15:42:29 -04:00
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 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

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.
