Thanks, Simon, This is what I thought was the case, and in fact I couldn't see it was not. In reality there -are- JBODs involved, so that was a somewhat hypothetical use case initially.

Message-ID: <[email protected]> Content-Type: text/plain; charset="utf-8" When you create the file-system, you create NSD devices (on physical disks ? usually LUNs), and then assign these devices as disks to a file-system. This sounds straight forwards. Note GPFS isn?t really intedned for JBODs unless you have GNR code.

Scenario: * one set of JBODS * want to create two GPFS file systems * want to ensure that file system A uses physical disks a0, a1... an-1 and file system B uses physical disks b0, b1... bn-1 * want to be able to assign specific sets of disks a0..an-1, b0..bn-1 on creation * Potentially allows all disks b0..bn-1 to be destroyed if required whilst not affecting a0..an-1 Is this possible in GPFS?
