Hi,
Yes, I've tried the command "vgchange -ay" and it gives me error message:
"Check of pool qubes_dom0/pool00 failed (status:1). Manual repair
required!
1 logical volume(s) in volume group "qubes_dom0" now active. "
That single active volume is 'swap'.
All other lv'sn (which I have 86) have "LV Status" set to "NOT
available", and I can't turn them back to active. Also vgchange wasn't
able to activate them.
Is there any other way to to get to the lv's of the LUKS encrypted
qubes disk?
Are there are any dedicated LUKS / LVM2 recovery tools (somebody
mentioned 'scalpel' but I have't tried it yet)?
I would be grateful for any hints into good direction of retrieving
data from my luks encrypted qubes disk.
You can try qtpie's procedure in
https://www.mail-archive.com/qubes-users@googlegroups.com/msg19011.html.
This one just bit me as well. Last I checked a month ago or so, I
thought I still had something like 250GB free in my primary lvm pool.
Maybe I was looking at the wrong line. I remember a Qubes notification
popped up unexpectedly around a week ago, but it disappeared before I
could read it. Didn't notice if the tray icon was any different
afterwards, but maybe it should start flashing or have a large red X
over it any time the pool containing root remains nearly full. I hope
this LVM failure mode is improved in 4.1. Recovery is painful.
I was only able to repair some of the LVM metadata with the above linked
procedure. The rest was corrupted. Luckily my critical VMs were among
the survivors so I could copy out their private volumes before the
reinstall, and had a recent enough backup of the rest. Hope you managed
to salvage some too.
