Thanks Saqib for your reply.

What happens if only one host mounts the storage for writing and all other hosts are read-only. In our application, the data is stored on one machine and is updated often. This data is exported to other machines using NFS in a read-only mode. The problem with NFS is that (I think) it is slow. I would like to know if read performance from NFS on a gigabit lan is equivalent to that from a locally attached disk. Our application, basically a search engine, requires fast reads (iostat shows around 300 tps and 3000 block reads per second).
May I ask why you want connect multiple machines to the same SAN slice? Is it for clustering?
The setup I mentioned was for user home directories. thanks, Nilesh Bansal. http://queens.db.toronto.edu/~nilesh/ -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
