[Nbd] Reconnect after server failure

[Georg Wassen <georgw@...116...>]

Hi all,

I'm wondering how to handle server disconnects, eg. when having a RAID on NBD 
connected devices. After one of the servers reboots, the module can't 
reconnect by itself, because it knows only the socket-handle, not the 
server's hostname and port. 
A solution could be a kind of heartbeat that detects server failures and 
reconnects after they're up again. Is anybody using RAID on NBD in a 
production environment or has an idea for this problem?

Kind regards,
Georg Wassen.
