So, if the cluster/afr volume is in the server specification instead of the
client specification, and the 1st server in the afr array goes offline, the
whole afr volume is unavailable for reads?
I ask, because I noticed that if I had afr in server.vol it would hang when
the other one went offline (in a :2 setup), but if I moved it to the client
specification, it always works, even when the other half was offline. I
think this is because in the client specification, I always had the local
server first.
Thanks!
