rsync - Oct 2005 - Rsync with OCFS (RAC)

Hello All

We currently use rsync for various jobs at our company. We are now
looking at using it to create an offsite synchronized copy of an Oracle
10g
RAC archive logs area. The source area is on Oracle OCFS file system.

The OCFS filesystem requires all reads/writes to be performed with the
O_DIRECT option, thus bypassing cache. Oracle provide an updated
coreutils package which includes the --o_direct switch in cp, tar, dd
etc
to allow "normal" file operations on OCFS filesystems.

My question is, is there a facility to ensure rsync reads files in
O_DIRECT mode so that we can use it for this purpose?


Many Thanks

Regards,

Wasn't this resolved just last week, with a message from someone who was
assured by Oracle that only writes need the O_DIRECT option on OCFS?
Reads are safe as-is.

Check the archive.
