Error if non-active vg/lv are present

[hwk]

The error seems unrelated to the "Couldn't find device with uuid". That only ensures that /vg_newlv_new isn't active.

Good catch. I'll have to work out how to retrieve all of the info I
want to display for inactive volumes.

It seems like this issue also causes it to fail with LVM Thin volumes. The thinpool itself is listed in the lvs output, but it's never present as a device file in /dev/vgname/ (even while active).

Just as a note, this is still an issue today.

A quick hack to make it work is to change line 479 to:

if lv_type == "cache-pool" or lv_type == "thin-pool":
