Subject [Ocfs2-users] ORA-19870 and ORA-19502 During RMAN restore to OCFS2 filesystem


 
Hi,
 
When attempting to restore to LINUX RHEL5 - OCFS2 filesystem received the following error during RMAN restore for nearly all of the datafiles attempted to restore with exception of a couple of smaller datafiles which were smaller < 2GB.
 
ORA-19870: error reading backup piece /db/dumps/TR1_1/rmanbackup/TR1_88_1


ORA-19502: write error on file "/db/devices/db1/PR2/pr2_1/pr2.data1", blockno 1409 (blocksize=8192)

ORA-27061: waiting for async I/Os failedLinux-x86_64 Error: 5: Input/output error
 
Tried various Oracle init parameters for filesystem i/o SETALL, ASYNCH, DIRECT and also disk_asynch_io settings.
 
After this failure tried to used a non ocfs2 filesytem (ext3) for the source RMAN backup files, however the error still occurred.  For testing purposes specified  a non ocfs2 filesystem ( ext3 ) as restore target filesystem and the RMAN restore completed successfully without any errors.
 
 
Let me know if you have any suggestions.
Thanks,
Ed
