Joshua Boniface 30ddeb0fee Update MOTD automatically on boot 
The cron every minute was pointlessly excessive considering this doesn't
actually change minute-to-minute.
 2023-09-01 15:42:29 -04:00
Joshua Boniface 86026de8ef Adjust colour scheme of MOTD 2023-09-01 15:42:29 -04:00
Joshua Boniface 8e1d005d43 Obtain more information for MOTD header 
Add model and serial numbers to the vendor, and put this on its own
line. Also use BASH for proper syntax formatting. Reformat the header to
be a more compact format.

Joshua Boniface b987c4ea8f Adjust GRUB_DIST and add UEFI regeneration 
Keeps the UEFI boot list cleaned and consistent

Joshua Boniface 144f519e76 Add rinse dependency for provisioner 2023-09-01 15:42:29 -04:00
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 08c8be66b3 Increase timeout threshold for freshness 2023-09-01 15:42:28 -04:00
Joshua Boniface 00482aec06 Fix the other instance too 2023-09-01 15:42:28 -04:00
Joshua Boniface da98a4d445 Ignore errors about removing keys 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.
 2023-09-01 15:42:28 -04:00
Joshua Boniface e4ccafee73 Add cgroup delegation override 
Required to solve the occasional
  libvirt: QEMU Driver error : Requested operation is not valid:

Joshua Boniface e8fe165e00 Further optimize ownership agent output 2023-09-01 15:42:28 -04:00
Joshua Boniface cbea6e284c Make ownership check consistent with cmk-agent 2.1 
The new CheckMK agent uses UID 998 (dynamic) for itself. This causes
ownership problems with the old logic of this check. Move instead to a
range, where the UIDs from 200-599 are reserved for administrators, and
check for this range explicitly. Also eliminates the exceptions for ceph
and 2000 from previous iterations.

Joshua Boniface 9e20e47903 Update freshness checks 2023-09-01 15:42:28 -04:00
Joshua Boniface d47d320bb3 Replace freshness and kernel_version checks 
Use an updated plugin from BLSE that uses needrestart instead of manual
parsing of these elements.

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 a87745d640 Fix name of task 2023-09-01 15:42:28 -04:00
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.

Joshua Boniface 056c325486 Add option for setting CPU governor 
Allows the administrator to set a CPU frequency governor if they need
to, though the default of ondemand is usually sufficient.

Joshua Boniface 55ec177919 Ignore errors restarting libvirtd 
This seems to inexplicably fail sometimes. We can just ignore it.

Joshua Boniface b814ec60f6 Add resolv.conf customization 2023-09-01 15:42:27 -04:00
Joshua Boniface ddecb94348 Disable unified cgroup heirarchy on kernel cmdline 
This is required on Debian 11 to use the cset tool, since the newer
systemd implementation of a unified cgroup hierarchy is not compatible
with the cset tool.

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 c9742fe2e5 Update tags and fix backup keys to var 2023-09-01 15:42:25 -04:00
Joshua Boniface 7c7ca4a229 Allow inter-cluster orphan NTP sync 
Due to the requirement of Ceph to have all peer nodes tightly
synchronized with each other to come online, PVC nodes need a way to
synchronize to each other even in the absence of an external time
reference. This is especially prevalent if a set of nodes are left
offline for an extended period (>1-2 weeks), since their hardware clocks
will drift. If the resulting Internet connectivity is then dependent on
a VM, this will cause a catch-22 and the cluster will not properly
start.

This configuration will accomplish that - if no suitable >6 stratum
peers are found, the hosts will enter orphan mode. Since they are now
all configured as "peers" with each other, they will collectively decide
on one of them to become the source and sync to it. A local stratum 10
fudge is added so that at least one of the nodes can become this source.

While this is not an ideal use of NTP, it is by far the cleanest
solution to this problem, and does not impact normal functionality when
the two configured stratum-2 servers are reachable.
 2023-09-01 15:42:25 -04:00
Joshua Boniface 027a819a83 Move some other tasks to bootstrap role

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.
 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.

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.
