[Lustre-discuss] Lustre failover of MGS

[neil rutter]

guys,

actually, the original cmds i ran did have the = signs for the 
--failnode=<nodename> arguments; i gave the wrong bash history info to 
kevin to analyse when he asked for them from the host :)

however, having said that, it's the NIDs that were missing from the 
hosts that fixed the issues i was having.

cheers
