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 55ec177919 Ignore errors restarting libvirtd 
This seems to inexplicably fail sometimes. We can just ignore it.
 2023-09-01 15:42:27 -04:00
Joshua Boniface 4cb2d7835c Add setting bridge_mtu to config 2023-09-01 15:42:27 -04:00
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 f25a80ff53 Add additional CMK checks 2023-09-01 15:42:26 -04:00
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 524f857f56 Add some Zookeeper configuration tweaks 2023-09-01 15:42:26 -04:00
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.
 2023-09-01 15:42:26 -04:00
Joshua Boniface b03ecf0125 Add -XX:+AlwaysPreTouch option for Zookeeper 2023-09-01 15:42:26 -04:00
Joshua Boniface b842276002 Lower keep count for Zookeeper vacuum to 3 
Required to keep disk space growth down when using zookeeper_logging
functionality.

Joshua Boniface 7e94dddb4c Ensure libvirtd restarts when unit changes 2023-09-01 15:42:26 -04:00
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.
 2023-09-01 15:42:26 -04:00

Avoids an issue where the pvcnoded service is stopped on non-bootstrap
runs.

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.
 2023-09-01 15:42:25 -04:00

Joshua Boniface 2bd5cc5a25 Tune Zookeeper memory usage 
Use Xms and Xmx=128M to reduce overall Zookeeper memory usage.
 2023-09-01 15:42:24 -04:00
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.
 2023-09-01 15:42:24 -04:00
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 2caed2ae12 Rename remaining "pvc_prov" items to pvc_api 2023-09-01 15:42:24 -04:00
Joshua Boniface 2a2d318dbc Change name of default API database

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.

Reenabling seems to work. Likely a bug due to Zookeeper not being
a proper systemd unit.
