[Linux-cluster] Diskless Shared-Root GFS/Cluster

[isplist at logicore.net]

Did you ever give it a try at all? I mean, isn't anything potentially 
devastating if it becomes broken? 

In my case, it's silly to have drives running on every server and then also 
having centralized storage. It would save power, heat and another level of 
failure if I could use a sharedroot system.

Of course, along the same lines, if it's too complex or finicky then it might 
not be worth the trouble... for now.
