Hi,

9.2.0.6 on RHEL3(2.4.21-27.0.2.EL),ext3 filesystems and trying to test direct i/o . Patch 2448994 applied.
But when I set filesystemio_options=directio (or setall) and restart the instance, it fails with :

ORA-00204: error in reading (block 1, # blocks 1) of controlfile
ORA-00202: controlfile: '/u01/oradata/BZZZT/control01.ctl'
ORA-27091: skgfqio: unable to queue I/O
ORA-27072: skgfdisp: I/O error

Am I missing something obvious?

any help appreciated
