[linux-lvm] VG is not found !

[linux-lvm] VG is not found !

[Igor Dumaire]

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 :

I can see volume group "lvm2" but not "lvm1"

vgscan -- found active volume group "lvm2"

I can display lvm2 info
# vgdisplay lvm2

but, not lvm1 info !
# vgdisplay lvm1
vgdisplay -- volume group "lvm1" not found

So, What do I do?

Thanks,
