Hi,
I wonder if anyone can help with a problem I'm having trying to setup multiple GNBD server nodes.
I have 2x GNBD servers configured which both have access to the same SAN storage backend with two clients connected. I currently have the 2 clients connected to the one node and the GNBD setup works fine. I am trying to introduce some further redundancy to the backend with the 2x GNBD Server nodes. Unfortunately I haven't been able to find any information on such a setup, apart from the odd snippet here and there about the cluster config.
If I understand correctly it works in the same way that a server is connected to a SAN, in that you need to setup multipath to see both GNBD servers from the client, which creates the two redundant paths back to the servers. Again I haven't been able to find any information on this apart from a really old mailing list, which didn't really help.
Can anyone help with this please?
Kind Regards
Tony
