Ocfs2 users - Mar 2006 - Redundancy capability of OCFS1 and OCFS2.

Hi All,

I did not see redundancy capability of OCFS (version 1 and 2) like mirror,
stripping, RAID.  If customer use SAN as shared storage for RAC and want to use
OCFS, how to make oracle files e.g. data files redundant.

Best regards,
HUy.

RAID capabilities are not the job of the filesystem (any filesystem).

Any SAN has hardware RAID, look into the firmware.

There is also linux software RAID, that could be used with cheap hardware and 
iSCSI to make a test environment.  Then again, if it's a test environment
you
don't quite need RAID.

But for anything serious to keep your Oracle datafiles, you have hardware RAID 
in the storage firmware.

The filesystem comes on top of that.
