<div> </div>
<div>Hi,</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>ORA-19870: error reading backup piece /db/dumps/TR1_1/rmanbackup/TR1_88_1</div>
<p>ORA-19502: write error on file "/db/devices/db1/PR2/pr2_1/pr2.data1", blockno 1409 (blocksize=8192)</p>
<p>ORA-27061: waiting for async I/Os failed</p>
<div>Linux-x86_64 Error: 5: Input/output error</div>
<div> </div>
<div>Tried various Oracle init parameters for filesystem i/o SETALL, ASYNCH, DIRECT and also disk_asynch_io settings.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div> </div>
<div>Let me know if you have any suggestions.</div>
<div>Thanks,<br>Ed</div>
