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.
Found an instance where two of these fired too close together, and
caused a fatal error. Use a write lock, and then catch the schema.apply
function in case it fails anyways.
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.
Major improvements to autobackup and backups, including additional
information/fields in the backup JSON itself, improved error handling,
and the ability to email reports of autobackups using a local sendmail
utility.
Adds additional information about failures, runtime, file sizes, etc. to
the JSON output of a VM backup.
This helps enable additional reporting and summary information for
autobackup runs.
