Description Corey Marthaler 2023-01-31 00:26:16 UTC 
Description of problem:
This LV does *not* have a filesystem on it, however it does have a LUKS volume, which I believe triggers the "File system found on crypt device" message. It then checks that LUKS volume and determines that "No file system found". Maybe those messages can be less confusing for the user by stating "Luks (or something generic like 'stacked') device found on ..." and then "No file system found on" versus the contradicting messages currently.


lvcreate --yes --type linear -n resize_lv  -L 30G resize_matrix  
Logical volume "resize_lv" created.

activating LV resize_lv -ay on virt-557.cluster-qe.lab.eng.brq.redhat.com
lvchange --yes -ay  resize_matrix/resize_lv

'echo "Str0ngP455w0rd###" | cryptsetup luksFormat /dev/resize_matrix/resize_lv'
'echo "Str0ngP455w0rd###" | cryptsetup luksOpen /dev/resize_matrix/resize_lv resize_luks'

Adding additional space to resize_matrix/resize_lv on virt-557.cluster-qe.lab.eng.brq.redhat.com
lvextend --yes --fs resize -L +364M resize_matrix/resize_lv 
  Size of logical volume resize_matrix/resize_lv changed from 30.00 GiB (7680 extents) to <30.36 GiB (7771 extents).
  File system found on crypt device /dev/dm-3 on LV resize_matrix/resize_lv.
  No file system found on /dev/dm-3.
  Logical volume resize_matrix/resize_lv successfully resized.
