We found following problem: 1.The 'drop tablespace xxx including contents and datafiles;' cannot delete physical file from OCFS volumn.The error is: ORA-01265: Unable to delete LOG /U01/oradata/test01.dbf ORA-27056: could not delete file Linux Error: 16: Device or resource busy 2.RMAN cannot backup to OCFS volumn: ORA-27061: waiting for async I/Os failed Linux Error: 1: Operation not permitted sometime the 'Linux Error' is device not exist. Anyone encounter these problems? I searched through OCFS mailing list on oss.oracle.com,but got no clue.Then I created a TAR on Metalink,still got nothing from them. Any suggestion is appreciated.Thanks in advance. Zhai --------------------------------- Yahoo! Mail Mobile Take Yahoo! Mail with you!
