OPatch failed with error code 22
Looking in the oraInventory showed a lock directory which was empty. Removing it didn't resolve the issue
[grid@rhel6m1 oraInventory]$ ls
backup  ContentsXML  locks  logs  oraInst.loc  orainstRoot.sh  oui
[grid@rhel6m1 oraInventory]$ cd locks/
[grid@rhel6m1 oraInventory]$ rmdir locks
Inside the .patch_storage there was another file patch_locked which had the information for which patch the lock is taken for
cat $ORACLE_HOME/.patch_storage/patch_locked
Locked for patch  :  21068539
Locked by class   :  rollback
Removing this file resolved the issue
rm $ORACLE_HOME/.patch_storage/patch_locked
