I will have 2 Postfix servers. One will be a backup of the other.
What is the easiest method to provide central storage to both of these boxes? My infrastructure is very simple: Just a lot of Xen hosts, so there is no SAN or anything.
Each Xen host does have RAID1 though.
I don't mind mounting NFS shares on each of those mail servers, as long as the NFS server wasn't a single point of failure. Is there such a thing as redundant NFS?
Any help would be appreciated
