Hello again, it now occurs to me why I had never used FS Labels. FS Labels can't be used for the root FS, and in our environment every other DASD/partition is placed under LVM control.
LVM also solves the same problem, it doesn't matter what the DASD drive letter may be vgscan locates it, and the fstab simply contains /dev/VGNAME/xxx and is thus DASD drive letter independent. It would seem to me that LVM is really the way to go to avoid the headaches Jim spoke of earlier, as it also allows FS's to span DASD too giving 3390-x model independence (plus stripping etc.). The floor is now open to comments ;-) Ciao Mark -----Original Message----- From: Mark Perry Sent: 16 October 2002 09:28 To: Linux on 390 Port Subject: RE: Antwort: Max number of dasd devices Hi John, no one every pointed that out to me before I just looked it up and according to the docs your right it does the job. I need to try this but I assume one could do the following: dasdfmt -l cdl ..... fdasd -a ..... mkreiserfs -l label_for_vol1 ...... mount -L label_for_vol1 ..... or place it in the fstab for a "mount -a": LABEL=label_for_vol1 ........ Much or the doc refers to e2fs and e3fs and xfs, although mkreiserfs supports a label keyword - do you know if this works OK with reiserfs on SuSE SLES-7 s390 and/or s390x?
