Joshua Boniface 8937ddf331 Simplify VM rename to preserve data
A rename is simply a change to two values, so instead of undefining and
re-defining the VM, just edit those two fields. This ensures things like
snapshots are preserved automatically.

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 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.
2024-02-02 11:37:29 -05:00
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 8419659e1b Ensure zkhandler is always cleaned up
Even if the subfunction of an API @ZKConnection call fails, the
zkhandler needs to terminate and clean up, or it leaves stuck threads
around.

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 362edeed8c Add backup reporting and improve metrics

utility.

Joshua Boniface 39c8367723 Add additional metainfo to VM backups
Adds additional information about failures, runtime, file sizes, etc. to
the JSON output of a VM backup.

autobackup runs.

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.
