I want to build an OES Linux cluster to host GroupWise, File and Print. I
want to use NCS as the clustering software. I want to find out if anyone
has any experience using the RDAC drivers for multipath io. NSS on Linux
does not support multipath IO, however this should be overcome by the use
of the RDAC drivers.

The other option is to utilise one of the traditional linux file systems,
such as ext3, which should support all of the services I want and as they
are managed by the LVM will support Multipath IO.

Any input would be greatly appreciated.
