[Gluster-infra] Gluster HA

[Guy Boisvert]

Hi,

     New to this mailing list.  I'm seeking people advice for GlusterFS 
HA in the context of KVM Virtual Machines (VM) storage. We have 3 x KVM 
servers that use a 3 x GlusterFS nodes.  The Volumes are 3 way replicate.

     My question is: You guys, what is your network architecture / setup 
for GlusterFS HA?  I read many articles on the internet. Many people are 
talking about bonding to a switch but i don't consider this as a good 
solution.  I'd like to have Gluster and KVM servers linked to at least 2 
switches to have switch / wire and network car redundancy.

     I saw people using 2 x dumb switches with bonding mode 6 on their 
servers with mii monitoring.  It seems to be about good but it could 
append that mii is up but frames / packets won't flow. So it this case, 
i can't imagine how the servers would handle this.

     Another setup is dual dumb switches and running Quagga on the 
servers (OSPF / ECMP).  This seems to be the best setup, what do you 
think?  Do you have experience with one of those setups?  What are your 
thoughts on this?  Ah and lastly, how can i search in the list?


Thanks!


Guy
