Lvextend w/ strict allocation policy

[rleon]

I have a request to use the remaining PE's to extend one particular lvol. The PE's break down into 2 x 4 disk.

The lvol already has 8 disk with 11776 LE's.

But when i try to do an lvextend to the next LE I get the following error.

#/usr/sbin/lvextend -l 11777 /dev/vgorPFSA/lvol14 /dev/dsk/c9t1d2

It is already set up with one LE on each disk.

( this is the middle where disk changes )
08624 /dev/dsk/c9t2d0 02156 current
08625 /dev/dsk/c9t2d1 02156 current
08626 /dev/dsk/c9t2d2 02156 current
08627 /dev/dsk/c9t2d3 02156 current
08628 /dev/dsk/c9t3d3 01280 current
08629 /dev/dsk/c9t3d4 01280 current
08630 /dev/dsk/c9t3d5 01280 current
08631 /dev/dsk/c9t3d6 01280 current

with the last one being ..

11768 /dev/dsk/c9t3d3 02065 current
11769 /dev/dsk/c9t3d4 02065 current
11770 /dev/dsk/c9t3d5 02065 current
11771 /dev/dsk/c9t3d6 02065 current
11772 /dev/dsk/c9t3d3 02066 current
11773 /dev/dsk/c9t3d4 02066 current
11774 /dev/dsk/c9t3d5 02066 current
11775 /dev/dsk/c9t3d6 02066 current


The question is do I add the other 3 disk to do my lvextend?

What will it do if since i only want to test by extending to the next LE 11777.

Thanks

opps error is:

#/usr/sbin/lvextend -l 11777 /dev/vgorPFSA/lvol14 /dev/dsk/c9t1d2
Warning: rounding up logical volume size to extent boundary at size "47120" MB for striping.

Failure possibly caused by strict allocation policy

[Sandman!]

From your posting it looks like the lvol is striped across four PVs so what you are trying to do is invalid. Please post (better attach) output of the command:

# lvdisplay -v /dev/vgorPFSA/lvol14

I already have 8 disk in the lvol. I need to add 8 more disk that have free PE's and that are part of the vg.
---------------------

You need to lvextend lvol14 over 4 PVs only in order to take care of the striping requirements. You don't need to add 8 PVs in order to do what you are trying to.

~hope it helps

[Sandman!]

I hit the button prematurely...what I was trying to say is that you can lvextend lvol14 by a multiple of 4 extents owing to the striped policy viz.,

#/usr/sbin/lvextend -l 11779 /dev/vgorPFSA/lvol14
OR
vgextend vgorPFSA by 4 PVs and then lvextend lvol14 onto them viz.,

[tkc]

Earlier, when the logical volume /dev/vgorPFSA/lvol14 got created, it was probably created using the -i option to set the number of disks in the volume group as 4.
