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.
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.
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.
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.
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.
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.
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.
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.
