Error during rapid clone on pasteBinary.sh, exit code 255

I needed to run a clone and was running into a really head scratcher. As is Oracle\'s way they sometimes enjoy giving us DBA's a bit of detective work to do. As usual I kept knocking my head into various brick walls instead of tracking back through the logs. Eventually I came up with the problem

Start to configure the run filesystem. You can do a dualfs from AD-TXK Delta 7 but for now I just needed to get this up and running:
perl adcfgclone.pl appsTier
START: Creating FMW Home.

Oracle has left me a cryptic error and I come up with this note on MOS: Timeout Error Encountered for pasteBinary.sh While Running "adop phase=fs_clone" (Doc ID 1599424.1). Quite excited I run is again but again it fails. Again not reading the logs I think it has something to do with a possible firewall on the system. Also not the case and after some searching the logs reveal this is the error:

Solution

Because this is a clone of the same instance the mount points have become stale. Most of the times you'll get an error straight out the bat when working on something like this. So I remounted the instance and the clone happily continued.
umount /u03
mount /u03
