The problem with this approach is that a reboot is required before fdisk will recognise the increased the disk size (even though blockdev can see it) and the kernel will not load a new partition table if the disk is in use. This means that a drive expansion requires reboot into runlevel 1. I was hoping for an online solution.

Is is possible/useful to create pools on top of LVM on top of hardware raid? Would that help in this situation?
Does anyone use gfs on hardware raid?

I though pool-tool -g would do it but it seems that can only add subpools.
Is there any particular reason you don't want to add a subpool? As far as I know, adding subpools is the only way to grow a pool, and won't have any other effect than a slightly longer pool configuration file...
Perhaps there is a better way. I am still testing so I can recreate it differently if necessary.
