Joshua Boniface 5d0e7931d1 Add support for rolling back snapshots
We supported creating snapshots, but not doing anything with them. This
removes the manual task of restoring a snapshot and replace it with a
PVC abstraction of rolling back to a snapshot.

While Ceph recommends cloning a snapshot instead of rolling back, due to
the time taken, in our usecase I don't think that is an optimal
strategy, as it will leave dangling clones that we'd then have to
manage.

Closes #183

Joshua Boniface 3bc500bc55 Permit duplicate VNIs in templates with flag
Supports niche usecases whereby a network template should contain the
same VNI(s) more than once.

Joshua Boniface a95e72008e Add size validations for volume clones
Adds the same validations as a volume add or resize to volume clones, to
ensure there is enough free space for them.

Joshua Boniface efc7434143 Add safety check for 80% full size
Adds a check that a volume creation or resize won't violate the 80% full
rule for the storage cluster. This ensures a cluster won't get too full
if a storage volume fills up.

Also adds a force flag throughout the pipeline to override this check,
should an administrator really want to do so.

Closes #177

Joshua Boniface 09269f182c Add live migrate max downtime selector meta field
Adds a new flag to VM metadata to allow setting the VM live migration
max downtime. This will enable very busy VMs that hang live migration to
have this value changed.

Joshua Boniface 4969e90f8a Allow enable/disable of Prometheus endpoints
Since these are unauthenticated, it might be the case that an
administrator wishes to completely disable these metrics endpoints.
Provide that option via pvc.conf through pvc-ansible's existing
enable_prometheus_exporters option and the new enable_prometheus
configuration flag.

Defaults to "yes" to provide all functionality unless explicitly
disabled, as the author assumes that the PVC API is secured in other
ways as well and that metric information is not completely sensitive.

Joshua Boniface 102c3c3106 Port all Celery worker functions to discrete pkg
Moves all tasks run by the Celery worker into a discrete package/module
for easier installation. Also adjusts several parameters throughout to
accomplish this.

Joshua Boniface 24cabd3b99 Fix missing result_backend on Debian 10/11
For whatever reason, a Celery worker on <5.2.x was not picking these up.
Move them back to the root of the module so they are properly picked up
on these older versions but still prevents calling the routing functions
during an API doc generation.
2023-11-25 15:35:25 -05:00
Joshua Boniface b66cfb07d8 Isolate cluster-dependent Celery startup
Avoids calling unworkable functions when generating API docs etc. by
isolating them into a Celery startup function called by Daemon.py.

Also update to Celery 4+ settings format.

Joshua Boniface 0cb81f96e6 Use custom task IDs for Celery tasks
Full UUIDs were obnoxiously long, so switch to using just the first
8-character section of a UUID instead. Keeps the list nice and short,
makes them easier to copy, and is just generally nicer.

Could this cause uniqueness problems? Perhaps, but I don't see that
happening nearly frequently enough to matter.

Joshua Boniface 484e6542c2 Port remaining tasks to new task handler
Move the create_vm and run_benchmark tasks to use the new Celery
subsystem, handlers, and wait command. Remove the obsolete, dedicated
API endpoints.

Standardize the CLI client and move the repeated handler code into a
separate common function.

Joshua Boniface af8a8d969e Ensure queues are set up for non-coordinator nodes
Allows a runner to operate on every possible node, not just
coordinators, as OSDs or other things could be on any node.

Also add more comments.

Joshua Boniface a6caac1b78 Add Celery queue routing for tasks
By default, tasks will continue to run as they did, on the primary
coordinator's task runner. However this opens the possibility for
defining more tasks that will run on other nodes or coordinators.
2023-11-04 14:29:59 -04:00
Joshua Boniface 54215bab6c Switch to ZK+PG over Redis for Celery queue
Redis did not provide a distributed solution for the worker, which
precluded several important planned functions. So instead, move to using
Zookeeper + PostgreSQL as the broker and result backend respectively.

Should be a seamless drop-in change but for future uses requires the
database host to be the primary coordinator IP rather than localhost, so
that writes can occur to the database from non-primary hosts.

Joshua Boniface 64e37ae963 Update OSD replacement functionality
1. Simplify this by leveraging the existing remove_osd/add_osd
functions, since its task was functionally identical to those two in
sequential order.
2. Add support for split OSDs within the command (replacing all OSDs on
the block device(s) as required).
3. Add additional configurability and flexibility around the old device,
weight, and external DB LVs.

Joshua Boniface 980ea6a9e9 Adjust handling of ext_db and _count options
Avoid the use of superfluous flag options, default them to none, and add
support for fixed-size DB LVs.
2023-11-02 13:29:47 -04:00
Joshua Boniface 526a5f4a74 Add support for split OSD adds
Allows creating multiple OSDs on a single (NVMe) block device,
leveraging the "ceph-volume lvm batch" command. Replaces the previous
method of creating OSDs.

Also adds a new ZK item for each OSD indicating if it is split or not.

Joshua Boniface 35e27f79ef Fix uploading of non-raw image files
Adds a new API query parameter to define the file size, which is then

to work properly in qemu-img convert.
