help! unable to do lvextend on vg00

Alan Casey — Sat, 19 Nov 2005 09:34:26 GMT

vg00: (mirrored)
/dev/dsk/c1t15d0
/dev/dsk/c3t15d0
800MB free space
I want to increase an lvol by 200MB
When I do this in single user mode I get:
"Not enough free physical extents available"

Hi Alan:

Well, that's not a great deal of information to go on. What logical volume? Is that the complete message, or is it that you do not have enough contiguous extents? Did you specify your new size in *extents* when you meant to do so in megabytes? Is it simply that you do not have enough free space to keep mirrored extents on separate physical volumes (the default action)? I suspect that this is the most likely reason.

Regards!

Hi Alan:

OK, it looks like you do not have enough free extents on *both* physical* volumes. You have 254 free PE in the volume group, but you must you are asking for (852 / 4) or 213 PE on *EACH* logical volume. Thus you need 426 PE available which you don't have. Hence, "not enough free physical extents".

thanks James,
I'll see if there is anything I can move from vg00 to another vg
