How to find out disable lv's in vg.

[sathish subramani]

when we type vgdisplay -v vg04 it is showing that there are two current lvs available and open lv is zero.

It occur due to we have accidently deleted an LV source file.so we are unable to see the lv's .Kindly provide an solution for this.

This is an screen shot of output:

# vgdisplay -v vg04
--- Volume groups ---

Hey;

In addition to posting the ls of /dev/vg04, also post:

mount | grep vg04
ll /etc/lvmconf/vg04*

If you have inadvertently deleted the LVs then it may be possible to recreate them. See this thread:

if the volume group can be deactivated then a vgexport and vgimport will recreate as well.

vgchange -a n /dev/vg04
vgexport -m /tmp/vg04.map
vgimport -m /tmp/vg04.map /dev/vg04

The device files for the lvols are missing, re-create them:

mknod /dev/vg04/lvol1 b 64 0x040001
mknod /dev/vg04/rlvol1 c 64 0x040001

mknod /dev/vg04/lvol2 b 64 0x040002
mknod /dev/vg04/rlvol2 c 64 0x040002


and check with

vgdisplay -v vg04

Heh:

Torsten stole my thunder! His post was the exact reason I was looking for the command output - to recreate the lv devices manually.

Glad to hear things are working again...
