Joshua Boniface 4f5dbee8ee Correct bugs during bootstrap

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 750cb4b55c Disable pvc-flush service while rebooting 
Prevents the flush daemon from starting on node boot, before the
playbook is actually ready to unflush the node.
 2023-09-01 15:42:24 -04:00
Joshua Boniface cdc7e3377b Tweak oneshot script 
Cleanly stop daemons; check if OSDs are back before continuing; wait
less
 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 075ce8ea22 Add PVC status MOTD script 2023-09-01 15:42:24 -04:00
Joshua Boniface 68a475ccf9 Set proper mode on agent plugins 2023-09-01 15:42:24 -04:00
Joshua Boniface 9962ceaf0a Add cluster safe update playbook 
This playbook will perform a oneshot upgrade of the systems in the
cluster, including performing a clean and safe reboot of the node(s) if
required (either due to services needing a restart, or the kernel
changing). It runs in serial=1 and only reboots if needed.
 2023-09-01 15:42:24 -04:00
Joshua Boniface f86ec62416 Add check-mk-agent plugin installs 
These are used by various Ansible tasks, even if the administrator is
not using Check_MK for monitoring.
 2023-09-01 15:42:24 -04:00
Joshua Boniface 62d53b0c9c Add PCI and USB utils 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.
