Fixes #8251
The
nomad volume deregister
command currently returns an error if the volume has any claims, but in cases where the claims can't be dropped because of plugin errors, providing a-force
flag gives the operator an escape hatch.If the volume has no allocations or if they are all terminal, this flag deletes the volume from the state store, immediately and implicitly dropping all claims without further CSI RPCs. Note that this will not also unmount/detach the volume, which we'll make the responsibility of a separate
nomad volume detach
command (see #8252)
