lvextend error

mjos — Thu, 22 Nov 2007 13:51:05 GMT

Hi, I am trying to extend a logical volume, getting the following error on 11.23

lvextend -L 11000 /dev/vg_ap/lvken1
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg_ap/lvken1" could not be extended.
Failure possibly caused by strict allocation policy

"Not enough free physical extents available"

Check this with

vgdisplay -v vg_app

"possibly caused by strict allocation policy"

check with

lvdisplay -v /dev/vg_ap/lvken1

Hi:

You don't have enough free physical extents in your volume group to satisfy the request.

Your PE size is 4MB and you have 1058 free extents. With the 1500 already allocated to 'lvken1':

( 1500 + 1058 ) = 10,232 < 11,000

Regards!

Hi (again):

Sorry, that caclulation should read:

( 1500 + 1058 ) * 4 = 10,232 < 11,000

Regards!
