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 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 be091f66d4 Remove pvc-flush references 
This service causes more problems than it solves usually, so it is being
removed in the next PVC version.
 2023-09-01 15:42:28 -04:00
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 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.
 2023-09-01 15:42:28 -04:00
Joshua Boniface 55ec177919 Ignore errors restarting libvirtd 
This seems to inexplicably fail sometimes. We can just ignore it.

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.
 2023-09-01 15:42:27 -04:00
Joshua Boniface 83bd1b1efd Install cset configs even if disabled 
The setup script handles this instead.
 2023-09-01 15:42:27 -04:00
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.
 2023-09-01 15:42:27 -04:00
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 8c2d117a3c Wait longer when restarting services 
From 15 -> 30 seconds to ensure more time for stabilization before
proceeding with the next.
 2023-09-01 15:42:26 -04:00
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 13556918d7 Disable any systemd start rate limiting 
Because Zookeeper is supremely stupid (see last commit) we want to
disable start limiting. It needs to keep trying forever until it starts.
 2023-09-01 15:42:26 -04:00
Joshua Boniface 8eecc95f2f Ensure Zookeeper restarts itself 
The Zookeeper daemon does not appear to exit with any status other than
0, even after a fatal error. Work around this.

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.

Joshua Boniface 4f5dbee8ee Correct bugs during bootstrap 
1. Ensure Zookeeper restarts and checks out successfully before
proceeding with other steps.
2. Make sure PVC itself doesn't start prematurely.

Joshua Boniface 2bd5cc5a25 Tune Zookeeper memory usage 
Use Xms and Xmx=128M to reduce overall Zookeeper memory usage.

Joshua Boniface b4e36d146a Add tuning for Ceph OSDs 2023-09-01 15:42:24 -04:00
Joshua Boniface 24764fe704 Don't use libjemalloc for Ceph daemons 
This was an artifact of a much, much older Ceph configuration I ran, and
is not relevant with newer Ceph versions like those used in PVC.
Performance testing with Nautilus and Bluestore reveals a minimal
performance hit, and using `jemalloc` prevents cache autotuning from
being effective, so remove it.
 2023-09-01 15:42:24 -04:00
Joshua Boniface 458e7b4872 Use new init command location 
Command was renamed in the PVC CLI to facilitate other "task" actions
like backup/restore.
 2023-09-01 15:42:24 -04:00
Joshua Boniface bcb5962353 Add jute.maxbuffer to Zookeeper environment ops 
Adds this option based on the findings of
https://github.com/python-zk/kazoo/issues/630, whereby restores of >1MB
in size would fail. This is considered an unsafe option, but given our
usecase no actual znode should ever exceed this limit; this is purely
for the large transactions that come from a `pvc task restore` action to
an empty Zookeeper instance.
