The `volume detach`, `volume deregister`, and `volume status` commands
accept a prefix argument for the volume ID. Update the behavior on
exact matches so that if there is more than one volume that matches
the prefix, we should only return an error if one of the volume IDs is
not an exact match. Otherwise we won't be able to use these commands
at all on those volumes. This also makes the behavior of these commands
consistent with `job stop`.
When the `-verbose` flag is passed to the `nomad volume status` command, we
hit a code path where the rows of text to be formatted were not initialized
correctly, resulting in a panic in the CLI.
The AWS EBS CSI plugin was observed to return a EOF when we get to the end of
the paging for `ListSnapshots`, counter to specification. Handle this case
gracefully, including for `ListVolumes` (which EBS doesn't support but has
similar semantics).
Also fixes a timestamp formatting bug on `ListSnapshots`
If a plugin returns an error, we should continue at the outer scope to query
the next plugin, otherwise we just retry the plugin we got an error
on (potentially infinitely if it's an invalid request like an unsupported
plugin).
Add new commands for creating, deleting, and listing external storage
volumes. Includes HCL decoding update for volume spec so that we can humanize
capacity bytes input values.
Callers of `CSIVolumeByID` are generally assuming they should receive a single
volume. This potentially results in feasibility checking being performed
against the wrong volume if a volume's ID is a prefix substring of other
volume (for example: "test" and "testing").
Removing the incorrect prefix matching from `CSIVolumeByID` breaks prefix
matching in the command line client. Add the required elements for prefix
matching to the commands and API.
Add mount_options to both the volume definition on registration and to the volume block in the group where the volume is requested. If both are specified, the options provided in the request replace the options defined in the volume. They get passed to the NodePublishVolume, which causes the node plugin to actually mount the volume on the host.
Individual tasks just mount bind into the host mounted volume (unchanged behavior). An operator can mount the same volume with different options by specifying it twice in the group context.
