nomad volume status -verbose command crashes because of out of range index access:

Something is definitely wrong with this code:

nomad/command/volume_status_csi.go

Lines 122 to 123 in 09bd336

	rows := []string{}
	rows[0] = "External ID|Condition|Nodes"

Hi @ivoronin! Can you provide the output of nomad version please (from the CLI and the server would be helpful).

[ivoronin]

Both clients and servers are running 1.1.1:

# nomad version
Nomad v1.1.1 (7feec97c04de4f8afff54ca9e56d66a61dfbfeb3)

[tgross]

Thanks. Yeah that's obviously a bug. 🤦 Looks like it first landed in 1.1.0. I'll push a PR up to fix it and it'll go out in the next patch.

#10818 has been merged and will land in Nomad 1.1.3.
