I was trying to take RMAN backup from RHEL 5 for a database residing on fedora 13
but the NFS share is getting me the following error
ORA-19504: failed to create file "/backup/weekly/1qmp0vv3_1_1"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 3
Here the 10gR2 doc link
Otherwise, as already suggested, there're a numbers of notes in Metalink you should look at, it could really be a bug which may require an upgrade (10.2.0.1 is out of date anyway).
Too late, but glad you fixed it, thanks for your feedback.
