If you haven't yet bought hardware for the NFS, NetApp makes this a snap
with SnapMirror. I don't remember all of the ins and outs, but its
perfect for situations like this, its very bandwidth efficient, and its
got the same bullet-proof reliability their products are known for.
We currently use a Solaris Enterprise 250, old, but stone cold reliable.
I'll need something in the other NOC. I've not looked at NetAPP.
Otherwise I'd think your SAN vendor should have some form of block level
This is where I am headed. We are looking at SANiq (Lefthand Networks)
which can do volume replication in realtime. I am thinking that a NFS
server in each location, sharing a iSCSI volume, would be worth looking
into. Let the SAN keep the two volumes in sync and let NFS handle the
multiple access to the volume.
Hope that helps,

Subject: [vchkpw] NFS Clustering
We have been tasked with splitting our mail services between our two
NOCs. We have ordered a 1GB fiber connection between both locations.
We will be moving one of two mailgateways, two of four pop toasters, and
one of two smtp servers to the second NOC. Both border routers will be
BGP advertising the same IP range and each location will have hardware
load balancing. I can easily setup replication for my MySQL backend, but
my NFS mail store is another concern.
Is anyone else working with this type of configuration? I've not yet
looked into NFS clustering or what may be involved. (I will have a iSCSI
based SAN available which will have nodes/modules in both geographical
locations, which may help).
Any advice on what methods/tools work well is appreciated.
Three years now I've asked Google why they don't have a
logo change for Memorial Day. Why do they choose to do logos
for other non-international holidays, but nothing for
Maybe they forgot who made that choice possible.
