Yep got that problem on my SGI at the moment. I tried xfs_restore but that
said there are lots of errors and it fixed most probs but I decided to
recover all the data I can and pull the rest from my DLT backup tape
system. I'm going to first run dd on the disk to write zero to the whole
disk then I'll partition it and do a new mkfs. I will then test the disk
for bad blocks and errors. I take it you have the data on tape or another
media?
