Adds additional polled information on node cpu, memory, and network
bandwidth for the node running the test. This should provide additional
useful information about the results of the test.
Also bumps the test format to 2 to ensure clients can handle the changes
properly.
Modifies pvcapid to run under Gunicorn when in non-debug mode, instead
of the Flask development server. This is proper practice for one, and
also helps increase performance slightly in some workloads (file uploads
mainly).
Allows an imported volume to be scanned for stats independently.
Designed to be used as part of a snapshot import via API, to allow the
"create" to happen before the real import (to check for available space,
etc.) and then run this import after when the RBD volume actually
exists.
Some newer servers do not report NVMe device paths properly using
`lsscsi` as expected. To work around this, add an `nvme`-based detect
parser that is called if the `lsscsi` parser returns a `-` (or None).
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.
With the original system, the failure of one VM's backups would not
trigger a total fault, thus allowing other backups to complete.
Restore that behaviour.
Avoid trying to subcall other Celery worker tasks, as this just gets
very screwy with the stages. Instead reimplement what is needed directly
here. While this does cause a fair bit of code duplication, I believe
the resulting clarity is worthwhile.
