This would only be the case if you were running a fileserver with inode 
partitions, which you hopefully are not. Does /vicep*/AFSIDat exist? 
Then you have namei partitions, which should allow for such stunts.

This will work. Alternatively (if the data volume is large), you might 
prefer moving part of it away, then shrinking your ext3 partition and 
adding another (effectively splitting your space).

Moving data back is only necessary if you want that data to be on that 
particular server, too.

Is that the newest one available in your Debian? Upgrading fileservers 
is not dangerous, so I'd recommend it.
