Fred is most probably correct here. the two errors are not necessarily the same.
Turns out Fred was incorrect and having pushed the bad disk out the file system the backups magically started working again. Not that, that should come as the slightest surprise to anyone.
However finding I have a bad disk because the backups are failing is not good at all because it means I can't rely on GPFS's health monitoring to accurately report the state of the file system :-(
It also begs the question with hundreds of I/O errors on a disk why was it not failed by GPFS? What criteria does GPFS use for deciding if a disk is bad as clearly they are not accurate.
