Just create/add another nsd.

perhaps mmnsddiscover will do it for you, I guess not though...
You should be able at the worst case increase the disk size, then do a
mmdeldisk and an mmadddisk to reimport each disk at the new size. If memory
serves though the meta size is based on the size of the first disk that is
imported and won't increase, which affects how large your pool can actually
grow to. I'm sure there are workarounds to that though.

Hello,
Does anyone know if GPFS allows the increase in capacity of already existing
nsd/disks, in order to add capacity to a storage pool?
I need to increase the space on an existing filesystem, and wonder if rather
than having to add new nds/disks to the storage pool, I could leverage the
ability of the backend block storage array (NetApp E5600) to increase the
capacity of existing raid volumes, and propagate the increase in space all the
way through nsd/disk/storage pool. Sounds somewhat close to handling thin
disks – yes, not quite the same, but I found no reference in the manuals either
way.
Many thanks!
