[Linux-cluster] cluster slows down when a cluster member fails



Hi,

I'm newbie to clustering. I set up a 2 nodes cluster.
I don't claim any special.
I just want 2 linuxes to see the same GFS partition on an IBM storage.
It works but if one of the cluster members fails the other one slows
down. Mainly when I try to come at the mounted GFS partition.

What can be the problem?

thanks in advance

Attila
