[Lustre-discuss] Lustre clients failing, and cant reconnect

[Brock Palen]

Looks like that didn't fix it.  One of the login nodes repeated the  
behavior.
The strange thing is that the MDS does not show anything about the  
NID of the client.  The client just says it lost connection with it,  
but the MDS never says it has not heard from the client and is  
kicking it out.

Very strange.
