[gpfsug-discuss] Increase volume size after nsd/disk creation

[Popescu, Razvan]

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!
