I encounter a problem,I make a lvm VG on /dev/hda7,but after a re-patition,/dev/hda7 
becomes /dev/hda6, my lvm doesn't work,how can I get back my lvm VG????,I think I 
didn't touch the data stored on previous /dev/hda7.I don't know if my data on the VG can be retrieved??

I have setup a VG on a softraid system consist of 3 disks,I name the VG as lvmraid and make a ext2 file system on it,It can be mounted to a dirctory and work well,but after I reboot the system,I can't find the VG,the proc system also doesn't show it and I can't use vgremove to remove it.
what is wrong with it,helllllllllllllllllllllp!!!this has troubled me for two days

is there a "vgchange -ay" somewhere in your init procedure?
is LVM a module or is it compiled staticly into the kernel?

Look at section 7.5

Are the following two lines in your rc.sysinit?

Do that after you activate your raid.

# activating volume manager
vgscan
vgchange -a y

When you shutdown you must....

vgchange -a n

do that just before
mount -n -o remount,ro /

[linux-lvm] It doesn't work

think for your reply,I have added those commands in rc.sysinit,but it still doesn't work.
vgscan cann't find the volume set up on softraid partitions.
