(perhaps no :-( ) There's no reason why you couldn't or shouldn't do this. If all you want is some shared storage and don't care about the single point of failure, then this is exactly what the device was intended for. :) > The cluster are going to serve a HA httpd service (I know, with this disk I > have a SPOF, but that is all I have, no money for more .-(( ) > > any suggestion with this scenario? It should "just work" as you described. NFS mount it on both nodes and point Apache at it as per usual. It'll probably work faster than a clustered file system solution. For redundancy, however, if you have enough disk space on the web nodes, you could set up mirrored storage using DRBD and run GFS on top of that. You'd end up with full redundancy and no need for the NAS (assuming, as I said, that nodes have enough space). Note that fencing would be absolutely mandatory if you use GFS or else either node failing would halt the cluster to prevent data corruption.
