Usually, GPFS should rule the placement of new files, and I assume that a restore of a file, in particular under a different name, creates a new file. So, if your backup tool does override that GPFS placement, it must be very intimate with Scale :-). I'd do some list scans of the capacity pool just to see what the files appearing there from tape have in common. If it's really that these files' data were on the capacity pool at the last backup, they should not be affected by your dead NSD and a restore is in vain anyway. If that doesn't help or give no clue, then, if the data pool has some more free space, you might try to run an upward/backward migration from capacity to data . And, yeah, as GPFS tends to stripe over all NSDs, all files in data large enough plus some smaller ones would have data on your broken NSD. That's the drawback of parallelization. Maybe you'd ask the storage vendor whether they supply some more storage for the fault of their (redundant?) device to alleviate your current storage shortage ?
