[linux-lvm] Expanding volume groups to fill a growing disk

[linux-lvm] Expanding volume groups to fill a growing disk

[Ben]

I'm new to LVM, so maybe I'm missing something basic, but it seems like LVM2 
makes it difficult to expand a VG. Or rather, it's easy if you want to just add 
another disk to the group, but I have a hardware RAID card that supports online 
expansion, and I'd like to use it.

Basically, I'm looking for a way to tell LVM "I know I partioned you on 
/dev/sda2 to be 500GB; now that I've expanded the disk with the raid card, I 
want to expand that volume group to fill the new space."

Do I have to use fdisk to make a new partition, and then use pvcreate followed 
by vgextend? That sounds like it would work, but it seems like there should be a 
cleaner way.

pvresize, at least in recent releases.

What version do I need?

[root@cash src]# pvresize --help
   pvresize: Resize a physical volume in use by a volume group

Not implemented.  Use pvcreate options.
[root@cash src]# pvresize --version
   LVM version:     2.01.08 (2005-03-22)
   Library version: 1.01.02 (2005-05-17)
   Driver version:  4.4.0

Ah, thanks, that should be good enough. I plan to upgrade to FC5T3 as soon as it 
comes out for the x86_64 Xen support it will hopefully provide. And also, it 
seems, for a working packaged version of pvresize. :)
