[linux-lvm] URgent - please Help - our main system is corrupt, no one can work!



Dear Sirs,

this is the second mail. I tried it this noon but got no answer so far, but
our whole 
production is down and I really have to fix it.

We use SUSE 7.3 with LVM. I have got /var and /tmp and /opt  an /home and
many 
Partitions without a filesystem for our database on a logical volume group
named quant.

The system was up and running. I added (with YAST2) one more logical volume
to the 
volume group, applied an restarted. The restart ist "strange", since only
parts of the 
systems come up.

For instance the /var directory claims to be mounted but is empty and cannot
be 
mounted, for they are not mounted !! In /procs/ not filesystem is shown as
mountet.
The / filesystem, which is out of the VM is in a read only state, some files
are there 
others are gone.
When I do vgdisplay the VM is shown as available, when I do vgdisplay -D it
is shown 
as unavailable.

I cannot afford any tests, since I do not have a backup of the database data
from today.

It looks for me as if the addition of the new logical volume wrote some
information in a 
place where it does not belong. Can I recover the old state without loosing
information?

With best regards
