When I try to extend 40 GB ,I am getting the below error.

# lvextend -L 703072 /dev/vgtest/lvol5
lvextend: Not enough free physical extents available.
Logical volume "/dev/vgtest/lvol5" could not be extended.
Failure possibly caused by PVG-Strict allocation policy.

Even though I have a free space why I am not able to extend the File system.

Please post the contents of the /etc/lvmpvg file.

[krissh89]

VG /dev/vgtest
PVG pvg01
/dev/disk/disk94
/dev/disk/disk88
PVG pvg02
/dev/disk/disk108
/dev/disk/disk150

[Patrick Wallek]

Your logical volume is only allowed to expand to /dev/disk/disk88, /dev/disk/disk94, /dev/disk/disk108 and /dev/disk/disk150.

According to your /etc/lvmpvg file disk88 and disk94 are in pvg01 and disk108 and disk150 in pvg02.  You LV is mirrored so one copy of mirror will be on PVG01 and the other on PVG02.

Now, if you do not have any available disk space on those particular disks, then you won't be able to extend this LV.

# vgdisplay -v /dev/vgtest

will show us how much space is availabe, if any, on these disks.

You may need to either add more disks to the VG or add disks that are already in the VG to the PVG01 and PVG02 physical volume groups.

1.So I need to get new two disk from different controller and add one disk to pvg01 and another disk to pvg02 by editing the /etc/lvmpvg file  .

2.after that How can i add those disk to VG.

can you give me the commands .
