Check for the free PE extents with command

vgdisplay vg00

Bonjour ldham,

OnlineJFS has no relation with LVM admin. It will be only necessary to increase size of the FS with "fsadm" after you extend lvol5.

What is said is that you have not enough PE. So, how many free PE in vg00 (vgdisplay) ?
Now, even you could have suficient PE, allocation policy can also restricts the use of them. So what is allocation policy of lvol5 (lvdisplay) ?

Re: lvextend fails

Thanks I think found the cause...which is my fault..I want to extend to 1GB..

should be
lvextend -L 1024 /dev/vg00/lvol5
I forgot that value after "-L" sholud be in MB size.

Anyway thanks for the help
