[Linux-cluster] Defending GFS

[gordan at bobich.net]

If it's having problems, it's usually detected pretty quickly, and when it 
gets detected it screams about it on the console and in the syslog, and 
disconnects the FS. The node most likely gets fenced at that point.

What distribution, kernel, gfs tools, etc. are you using? What is your 
shared storage?
