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 e4ccafee73 Add cgroup delegation override 
Required to solve the occasional

Joshua Boniface aa6b4ac3dc Make locale generation universal 
Don't rely on a notify/handler, just do it every time in the base role.

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.
 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 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 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 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 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.

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.

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 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.

We're 100% systemd here, and the lack of control/information that the

own simple unit file.

Joshua Boniface d8e9b5353f Don't try to set pool limits on libvirt key 
I figured a * wildcard would work, but no it doesn't. Libvirt needs
the ability to talk to any pool arbitrarily since PVC can create and

Joshua Boniface 6dc57f374b Revert "Keep zookeeper enabled" 
This reverts commit 5554418210.

This is not needed
 2023-09-01 15:42:20 -04:00
Joshua Boniface ebcd281490 Keep zookeeper enabled 
Without this, the service seems to just loop failing to start
indefinitely even though PVC attempts to start the daemon itself.
Reenabling seems to work. Likely a bug due to Zookeeper not being
a proper systemd unit.
