[gpfsug-discuss] Identifiable groups of disks?

[Marc A Kaplan]

The simple answer is YES.  I think the other replies are questioning
whether you really want something different or more robust against
failures.

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?
