Hi,
I have a machine, containing 2 harddisks. The main disk crashed, so i had
to reinstall the machine.
All my data is on the 2nd harddrive In VolGroup00-LogVol01, whilst i
reinstalled fc on VolGroup00-LogVol00.
I would like to mount my data again :-)
mount -t ext2 /dev/mapper/VolGroup00-LogVol01 /data -> according to the
lvm-howto on internet.
But this gives me just the following error:
mount: /dev/mapper/VolGroup00-LogVol01 is already mounted or /volume is in
use now.
neither /var/log/messages nor ./audit/audit.log nor dmesg are saying more
to me.
What did i do wrong?
Thanks for your help.

Okay, i found out, why this happened. The second disk has the same
Volume-Label like the swap-disk :-(
do i have the chance to rename the volume from the second harddisk???

How many PVs (physical volumes) does displayvg show? I suspect that your
second drive is not recognized as a valid LVM PV.

Hi,
I didn't find displayvg, but i hope the following information help you
either.

erm....correct, that /dev/sdb1 is in volume group?

it like a now volume group?

Sorry about that, so /dev/sdb is your current "new" install right, and
it is also on VolGroup00?

Also, look at "vgrename" and "lvrename"
http://www.die.net/doc/linux/man/man8/vgrename.8.html
http://www.die.net/doc/linux/man/man8/lvrename.8.html
You should be able to vgrename /old /new
I would suggest simply changing it to VolGroup01 or 02, you get the idea :D

Ok, the reason is probably doesn't have a name is because the new
install "sda" took the old name so it is probably all confused about
names.
What appears in /dev/mapper?
If you can get it sorted out through commands and getting it to
actually see the old name, a quick and possible solution is to
re-install on the new drive again, only when it comes to the lvm, edit
the configuration to use a different vg name. I think you are going
to have a problem getting it to see the name atm since it is taken up
by the new install.
also checkout out "vgchange -a"

So in summary, you had two physical volumes (HDs) combined into one
volume group (VolGroup00) and that was split into two logical volume
(LogVol00 and LogVol01).
In this case, the data on the second drive is pretty much toast unless
logical volume mapping is written to all physical drives of the volume
group. And if you had that, there's still a chance that sections of both
logical volumes where split between both drives.
This is at least how I understand how the Linux LVM works.
