[Linux-cluster] using GNBD with other cluster filesystem

[gaurav]

I had not exlored about using iSCSI with Oracle RAC.
i am now looking into that more seriously.(pl. pass on any links if u have )

Yes, since this is only for testing purposes,so i do not intend to use
multiple GNBD servers so i would not require to use the -c (caching)
option

regards

gaurav
