Public bug reported:
Hi,
The bootup process is stopping in 'emergency mode', I have to manually
intervene and perform a 'vgchange -a y' and after 3.5 minutes 6 logical
volumes are active (however I do have 7). Only then I can finalize the
boot process.
Subsequent (all) boots I have to intervene. lvdisplay fails to show one
logical volume, which is shown under /dev/mapper. This volume is not
used, just contained some offline data.
I also had an unplanned reboot a few days ago on the machine without
having it under a load. The lost LV was not in use at that time (has not
been mounted for a long time).
I've got one snapshot defined, which acts as a mirror (LV Size same as
origin), with only 4.31 % allocated to that snapshot.
When viewing the system with a live desktop only the 'cow' LV is shown
under /dev/mapper, none of the other LV's.
Why is this unused LV lost?
The data on the 'lost' LV is not needed at the moment. I'll leave things
'as is' for the moment for investigation.
