It was far too cumbersome to report every possible stage here in a
consistent way. Realistically, this command will be run silently from
cron 99.95% of the time, so all this overcomplexity to handle individual
Celery state updates just isn't worth it.
Moves VM autobackups from being in-CLI to being handled by the
pvcworkerd system on the primary coordinator. Turns the CLI autobackup
command into an actual API client endpoint rather than having its logic
in the CLI.
In addition, modifies the new autobackup to leverage the new "pvc vm
snapshot" function set, just with special snapshot names. This helps
automate this within the new snapshot scaffolding.
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
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
How this was being done didn't work, as the backup volume was already
unmounted when we tried to read the backups from it. Instead, populate
the backup summary earlier in the run, during the actual backup.
1. Use the actual response code from the server on error, or 504 on
timeouts instead of 500.
2. Retry GET requests 3 times and only error if the last fails
Shows each subarg of the task_args as its own element, if applicable,
and fits the width to the terminal using MAX_CONTENT_WIDTH instead of an
arbitrary value.
