Hi Taifur,

Check all the disks belongs to vgdev1 is available or not. It looks some of the disks are missing. Fix the disk issue and try to activate it.

You can also try to activate the vg with quorum overide. But for that more than 50% disks should be available.

To activate the volume group without quorum enforcement.

#vgchange -q n -a y /dev/vgdev1.

But some of the lv's are not accessible due to unavailablity of disks.

Hi,

Did you checked all the PV's are exist or not before and after rebooting.

check with
insf
insf -e
ioscan -fnC disk

If you have nickel output of your server before reboot then take one more nickel and check all physical volume are exist or not.

I think some PV's are missing.

Hi

Check the /etc/lvmrc file and set the AUTO_VG_ACTIVATION variable to 1.
This will activate all the vgs when server reboots

This vg is in /etc/lvmtab???? If not, please add in.
One things more, add all logical volume in /etc/fstab if you want OS mount them at startup.
