Hi.
I would like to avoid setting up a file server as back-end to my web server cluster, as this would give a single point of failure. Give we are running a iSCSI array of 8 nodes with redundancy and replication etc, I would like to take advantage of this.
It's the first time I'll be working with iSCSI from within Linux. A) is it possible and b) if it is, how do I best configure multiple machine to use the same iSCSI LUN / data store, as a "common share " . I assume I need a more advance file system that ext3.
If you share a block device with more than one computer you need a cluster file system. I suggest you look at GFS, which is part of Redhat and also in fedora among others. You may also find multipath useful if the backend block devices are highly available.
