Cannot deregister volume while its id is a prefix of other volume id.

Nomad version

1.2.5

Operating system and Environment details

Arch linux

Issue

I try to deregister volume which id is a prefix of other volume. But then I got an error

nomad volume deregister registry-volume
Prefix matched multiple volumes

ID                Name             Plugin ID  Schedulable  Access Mode
registry-volume   Docker registry  ceph-csi   true         multi-node-multi-writer
registry-volume1  Docker registry  ceph-csi   true         multi-node-multi-writer

It's non-critical and definitely a corner case as I can deregister registry-volume1 and then registry-volume.

Reproduction steps

Register 2 volumes registry-volume and registry-volume1. Then try to deregister registry-volume.

Expected Result

Volume matched by exact id should be deregistered.

Actual Result

There is an error that multiple prefixes was matched.

Hi @kriestof! We fixed a bug in the deregister prefix matching in #11852 which shipped in Nomad 1.2.4, where prefixes were used to deregister. But you're right, we should also have followed that up with changes to the CLI to account for exact matches, similarly to how we do for job ID.

I'm in the middle of a big set of work on CSI, so I'll make sure this gets added to that pile. Thanks!

Fixed in #12051 which should ship in Nomad 1.3.0
