Hi Mât,

Sorry for taking so long to respond.

Well, unfortunately I'm not quite convinced that it is the same problem. It may
be related, but not sure. Let's see:

I hope it's ok if I quote from the logs:

(CMD) vgchange -a n 1> /tmp/8wsOEujVJ4 2> /tmp/5IGEwxrwPJ
Executing: vgchange -a n
(STDOUT)   0 logical volume(s) in volume group "HEBEX" now active
(CMD) lvremove -f HEBEX/WOO_BASE 1> /tmp/gQaXBIln_D 2> /tmp/CANIq9LRKR
Executing: lvremove -f HEBEX/WOO_BASE
Command had non-zero exit code
(STDERR)   Incorrect metadata area header checksum
(STDERR)   Incorrect metadata area header checksum

Well, no, that's not quite true - setup-storage hasn't yet removed the partition
table or the like, these are really the first commands. Looking at the other
parts of your logs the partition /dev/sda9, which is what hosts the LVM, is in
place!?

I understand, and you would be completely right - if it were the case that the
disk label had been wiped already... To me it seems that something about your
volume group is wrong!? Is this system still available in this state, i.e., can
you either re-run the install or just go right were it stopped? IMHO you should
still be able to do vgdisplay -a, etc. and try to do the removal of the logical
volume manually. One question maybe: What is the state you expected this system
to be in? Did you expect WOO_BASE to be there? Could it be that /dev/sda9 had
been wiped in some earlier install and there's just some other information left
that made setup-storage discover WOO_BASE?

Thanks a lot,
Michael
