Customer’s requirements drive the solution, there are many ways to achieve HA storage. I don’t know your exact setup and resources but I reckon iSCSI will be just an unnecessary overhead layer if you are using GlusterFS. You can use DRBD with a clustered file system (e.g. gfs, ocfs, ..) or with xfs/ext3/4 + NFS, you may consider using G/NBD as well. Again, the solution is driven by the customer’s requirements and the available resources. GlusterFS is an awesome solution, provides HA & performance but it has some limited capabilities too, like it doesn’t support POSIX ACL. Lastly my 2cents for a clustered file system, it sounds like a sexy solution but if it’s deployed in a small scale (e.g. < 5 nodes) it might easily become a nightmare. For small scales HA storage without losing stability I’d recommend DRBD + XFS/EXT3/4 + NFS.
