Ran out of space on existing server
So installed a new NW65SP7 server from overlays
Then created a DATA: volume on the new server and moved the files from the DATA: volume on the old server to the new one
Deleted old DATA: volume
Everything appears normal and users can modify existing files and create new ones OK
But if they try to rename or move files they get an error of "file in use" or similar
Any ideas ?
