Sorry... I was a little bit worried. Anyway, I start to think it would 
be nice to have some kinds of "control node" concept where these admin 
commands can be performed on one particular pre-defined node. This would 
allow the tools to check and prevent mistakes like these (say fsck would 
start to ssh to each node to unmount the filesystem before it starts to 
do anything).  This is something to think about. After all, cluster 
system management is not a trivial task and mistakes can be plenty, 
regardless admins' skills.
