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 5a48ec4d79 Ensure CPU tuning is only applied on Debian 11+ 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 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 be091f66d4 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 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 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 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 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 6e2d661134 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 83bd1b1efd Install cset configs even if disabled
The setup script handles this instead.

Joshua Boniface 7927ec4f11 Allow dynamic enabling/disabling of cset
Add a separate config to handle enable/disable on the system itself.
2023-09-01 15:42:27 -04:00
Joshua Boniface 2ae9b9075a 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 6e48d6fe84 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.

Joshua Boniface 647ca1c446 Add default features flag to ceph.conf generator
Coupled with the removal of explicit --image-features flags to the RBD
command in PVC itself, this ensures that only the two features supported
on kernel 4.19 are enabled by default.

Joshua Boniface 0bbb91fc8b Add override custom libvirtd.service unit
This has no functional change on Buster, but on Bullseye this overrides
the stupid socket-based activation shenanigans that the default unit
tries to do, as well as the breaking replacement of the
/etc/default/libvirt variable names.

Command was renamed in the PVC CLI to facilitate other "task" actions
like backup/restore.

Joshua Boniface f79fb605de Support using existing SSL certs on system
Add the additional pvc_api_ssl_cert_path and pvc_api_ssl_key_path
group_vars options, which can be used to set the SSL details to existing
files on the filesystem if desired. If these are empty (or nonexistent),
the original pvc_api_ssl_cert and pvc_api_ssl_key raw format options
will be used as they were.

Allows the administrator to use outside methods (such as Let's Encrypt)
to obtain the certs locally on the system, avoiding changes to the
group_vars and redeployment to manage SSL keys.

Joshua Boniface fbbf5ffe09 Use cluster_group variable for paths
Instead of trying to automagic this group out of the Ansible hostvars,
just make it explicitly defined in the group_vars to avoid any
confusion.
