Moves the age human conversion logic to the client so that this value
can be used by API consumers programatically.
Rounding ensures recent snapshots are not showing as "older" than they
actually are, which is important for accuracy especially with
automirror snapshots and ages above half the next rounding value.
Allows shipping snapshots automatically to remote clusters on a cron,
identically to how autobackup handles local snapshot exports.
VMs are selected based on configured tags, and individual destination
clusters can be specified based on a colon-separated suffix to the
tag(s).
Automirror snapshots use the prefix "am" (analogous to "ab" for
autobackups) to differentiate them from normal "mr" mirrors.
Using full paths broke the local schema generator, so convert these to
proper class instance methods and use them along with a new default +
settable override.
Snapshot mirrors should normally be promoted using "mirror promote", and
not started manually. This adds guard rails against that to the "start",
"stop", and "disable" state commands to prevent changing mirror states
without an explicit "--force" option.
Adds two helper commands which automate sending and promoting VM
snapshots as "vm mirror" commands.
"vm mirror create" replicates the functionality of "snapshot create" and
"snapshot send", performing both in one single task using an
autogenerated dated snapshot name for automatic cross-cluster
replication.
"vm mirror promote" replicates the functionality of "vm shutdown",
"snapshot create", "snapshot send", "vm start" (remote), and,
optionally, "vm remove", performing in one single task an entire
cross-cluster VM move with or without retaining the copy on the local
cluster (if retained, the local copy becomes a snapshot mirror of the
remote, flipping their statuses).
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.
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.
