 Doing a restore will bring all the data back, data > 400GB which
 doesn't fit into a 140GB filesystem. Besides the time is costs to
 restore 400GB data....

 Stubs are not restored (because the filesystem isn't HSM).

 Well, the answer from IBM is: "HSM is not supported (yet) on IRIX 6.5.7"....
 I guess it will take a long time before this bug is fixed, and not because
 I'm a pessimist, but because the experience I have with these kind of
 bugs in the past (on AIX and on IRIX).

 Oh, btw, we have a "workaround": downgrade to IRIX 6.5.4, restore HSM-
 filesystem and upgrade to IRIX 6.5.7. And then just pray that we don't
 get a corrupted filesystem again...
 And we were busy to split one HSM-filesystem into two HSM-filesystems,
 which we also only can't do on IRIX 6.5.7...
