Symptoms

RMAN Backup / CROSSCHECK command on OCFS2 file system sometimes fails with errors like following:

RMAN-03009: failure of crosscheck command on ORA_DISK_1 channel at 04/19/2010 22:32:32
ORA-19501: read error on file "/rmanback/orcl/BP10P_20100410_a6lapg30_1_1.bkp", blockno 1 (blocksize=512)
ORA-27072: File I/O error
Linux-x86_64 Error: 9: Bad file descriptor

The file exists at OS level. Infact running CROSSCHECK specifically on same backup piece works fine later.
