Hello experts,
I need your advice to save some data: My old laptop died, but I could make
the HD work again via a USB-adapter. I attached it to the new Laptop (as
well running SuSE 10.0 / lvm2), and the lvm on the USB-Disk is not
displayed.
The lvm on the installed system is active:
z60m:~ # pvdisplay /dev/sda8
--- Physical volume ---
PV Name /dev/sda8
VG Name system
PV Size 28.75 GB / not usable 0
Allocatable yes
PE Size (KByte) 4096
Total PE 7359
Free PE 11
Allocated PE 7348
PV UUID ZdwaLr-anXc-Z7ck-cGI0-oFoW-UluI-F7SZ18
This group is also active:
z60m:~ # lvscan
ACTIVE '/dev/system/daten' [12.70 GB] inherit
ACTIVE '/dev/system/home' [8.00 GB] inherit
ACTIVE '/dev/system/root' [8.00 GB] inherit
Now, on the USB-disk is a LVM as well:
z60m:~ # pvdisplay /dev/sdb8
--- Physical volume ---
PV Name /dev/sdb8
VG Name system
PV Size 17.48 GB / not usable 0
Allocatable yes
PE Size (KByte) 4096
Total PE 4475
Free PE 9
Allocated PE 4466
PV UUID P8KDPg-QbME-4Hzc-lw8G-ntOA-1dIv-1DeXmR
vgscan does not activate the group on the USB - due to the same name?
z60m:~ # vgchange -a y
3 logical volume(s) in volume group "system" now active
z60m:~ # pvscan
PV /dev/sda8 VG system lvm2 [28.75 GB / 44.00 MB free]
Total: 1 [28.75 GB] / in use: 1 [28.75 GB] / in no VG: 0 [0 ]
z60m:~ # lvscan
ACTIVE '/dev/system/daten' [12.70 GB] inherit
ACTIVE '/dev/system/home' [8.00 GB] inherit
ACTIVE '/dev/system/root' [8.00 GB] inherit
What is your proposal to activate the USB-lvm group - best without loosing
data.....
TIA
Axel

Hi Axel,
vgrename the active one and adjust /etc/fstab appropriately.
'vgscan;vgchange -ay' should gain you access to the USB one then.

After deactivation I could change the name, but after the reboot the
dm-mapper was still looking for the old volume group 'system'. I tried to
boot the rescue system, maybe the inittab needed a refresh - but that did
not work.
unfortunately Suse's system repair cant deal with LVM, so my best idea was
to change everything back.
Cheers

Did you change /etc/fstab ?

The missing element was: Change settings for bootloader (/boot/grub/menu.lst)
The way it worked for me:
- change settings in /etc/fstab and /boot/grub/menu.lst
- boot the rescue system from CD (otherwise the volume groups are still active)
- do a vgrename / vgsan
- reboot
Cheers
