Hi all,
I have been a very happy Qubes 4 user for some time now and have had no
issues until the other day. I stupidly allocated a VM too much space and
totally filled the volume group, which crippled Qubes. When I would
login I couldn't even open the VM manager, let alone the backup.
I have tried fixing the problem by myself using a Linux Mint live-USB
(with much googling), and have added a new pv to the vg, but for some
reason was not able to expand the vg, move the vg, or even use any
command such as lvconvert --repair, vgchange. It turns out that lvm
thinks one of the pv is missing (my luks partition), and this stops any
attempt of repair, even when using --partial, etc.
I then realised when looking in /etc/lvm/archive that the vg file is
listing my first pv as an unknown device with a missing flag. I am
figuring this is a result of me having to mount the partition using
cryptopen to /dev/mapper/qubes. I subsequently corrected the path and
removed the missing flag (using this guide -
https://mbroz.fedorapeople.org/talks/LinuxAlt2009_2/lvmrecovery.pdf). I
then go to restore the corrected .vg file (sudo vgcfgrestore -f
/etc/lvm/archive/thevgfile.vg my_vg.. and get told that it cannot
restore the vg with thin logical volumes as it is not supported yet and
thus the restore failed.
I have tried googling my way out of this once again, but I'm afraid I am
stuck. I know the pv's are all fine, and the drives are working well
(apart from two of the pv being totally full). I have even tried booting
back into qubes but all I get is a terminal screen in which I can't
input anything on login, and the qubes live-usb recovery shell is no help.
Am I out of luck with this, or is there a way of correcting the missing
vg with thin logical volumes?
Have you reached out on a popular Linux forum such as Fedora or
StackExchange? Since this is specific to Linux lvm it would be better to
expose it to many more eyes than what we have here.
