VG is not found !
Hi,
I had created 2 VG and worked sometime with its.
I have stopped the server and at the reboot the first VG have disappeared ! The second it's OK !!
(perhaps, two drives (on 3) have been switched ) How can I restore the VG (vgrestore ?!) and the DATA ?
RH 7.1
LVM version 1.0.1-rc4(03/10/2001)
ReiserFS version 3.6.25
Linux 2.4.9
Thanks a lot for your help gays .

Start with these commands:
lvmdiskscan
vgscan
vgdisplay
vgchange -ay
Do not just blindly try the commands if you are not familiar with them;
read the manual pages first. Try the '--verbose' switch with each for more info.

Hi,
I can see all drives :
# lvmdiskscan lvmdiskscan -- reading all disks / partitions (this may take a while...) lvmdiskscan -- /dev/hda1 [ 70.57 MB] Primary LINUX native partition [0x83] lvmdiskscan -- /dev/hda2 [ 19.07 GB] DOS extended partition [0x05] lvmdiskscan -- /dev/hda5 [ 2.01 GB] Extended LINUX native partition [0x83] lvmdiskscan -- /dev/hda6 [ 1.00 GB] Extended LINUX native partition [0x83] lvmdiskscan -- /dev/hda7 [ 1.00 GB] Extended LINUX native partition [0x83] lvmdiskscan -- /dev/hda8 [ 517.69 MB] Extended LINUX native partition [0x83] lvmdiskscan -- /dev/hda9 [ 14.55 GB] Extended LINUX native partition [0x83] lvmdiskscan -- /dev/hdc1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- /dev/hdd1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- /dev/hde1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- /dev/hdf1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- /dev/hdg1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- /dev/hdh1 [ 57.27 GB] Primary LVM partition [0x8E] lvmdiskscan -- 7 disks lvmdiskscan -- 0 whole disks lvmdiskscan -- 0 loop devices lvmdiskscan -- 0 multiple devices lvmdiskscan -- 0 network block devices lvmdiskscan -- 13 partitions lvmdiskscan -- 6 LVM physical volume partitions
I can see volume group "lvm2" but not "lvm1"
# vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- found active volume group "lvm2" vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group
I can display lvm2 info
# vgdisplay lvm2 --- Volume group --- VG Name lvm2 VG Access read/write VG Status available/resizable VG # 0 MAX LV 255 Cur LV 1 Open LV 1 MAX LV Size 255.99 GB Max PV 255 Cur PV 3 Act PV 3 VG Size 171.79 GB PE Size 4.00 MB Total PE 43977 Alloc PE / Size 43776 / 171.00 GB Free PE / Size 201 / 804.00 MB VG UUID Jp3gDv-ib7D-p5te-FFLZ-lNjI-5brK-fzjEM6
but, not lvm1 info !
# vgdisplay lvm1 vgdisplay -- volume group "lvm1" not found
So, What do I do?
Thanks,
