Description Marius Vollmer 2019-03-11 12:37:37 UTC 
Description of problem:

Running "vdo create -n vdo0 --device /dev/vgroup/lvol" fails when the device is a LVM2 logical volume.

Version-Release number of selected component (if applicable):
vdo-6.2.0.293-10.el8.x86_64
lvm2-2.03.02-6.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1. vgcreate vgroup /dev/sda
2. lvcreate -n lvol -L 5G vgroup
3. vdo create -n vdo --device /dev/vdo_vgroup/lvol 

Actual results:
Creating VDO vdo
vdo: ERROR - Device /dev/vdo_vgroup/lvol excluded by a filter.

Expected results:
Creation succeeds

Additional info:
pvcreate fails in the same way:

# pvcreate /dev/vgroup/lvol 
Device /dev/vgroup/lvol excluded by a filter.
