Hi,

On the source fileserver. It did find some issues but did not fix the
move problem.

Just tried:

There is a read-only and a backup volume, but both on the source
fileserver, so there should be nothing.

Content before the salvage:

root@jena[openafs]# cd /vicepa/AFSIDat/M/MQY+U/
root@jena[MQY+U]# l
total 0
drwx------ 3 root root 14 Apr 24 21:03 .
drwx------ 3 root root 18 Apr 19 20:00 ..
drwx------ 3 root root 14 Apr 24 21:03 =

And after:

root@jena[MQY+U]# l
total 0
drwx------ 4 root root 28 Apr 25 16:50 .
drwx------ 3 root root 18 Apr 19 20:00 ..
drwx------ 3 root root 14 Apr 24 21:03 =
drwx------ 2 root root 24 Apr 25 16:50 special


I will try again tonight (using 'at').

Thanks,

Christopher
