Hi,
When a disk is missing the messages of the lvm tools are quite
verbose. Example output for a VG with a mirror LV:
Without patch:
# vgchange -ay -P
Partial mode. Incomplete volume groups will be activated read-only.
Couldn't find device with uuid 'egDxmo-sVp7-OQGB-6mgt-84mk-xioM-ahdzBw'.

2 logical volume(s) in volume group "main" now active
With patch:
# vgchange -ay -P
Partial mode. Incomplete volume groups will be activated read-only.
Missing PV with uuid 'egDxmo-sVp7-OQGB-6mgt-84mk-xioM-ahdzBw' in VG main
2 logical volume(s) in volume group "main" now active
