To have your data high available put it on a replicating GLUSTER vol
(glusterfs-as many Fileservers as you want).
Or replicate it with drbd master master (if 2 DCs are the limitation)

Good Luck

Hi Mike
Sorry, my English is over 30 years old! Can you give me a one liner on plugs
and HA in a S4 context?

We'd like to have a spare box with a backup of the data to substitute the
DC/fileserver. What do you think about the possibility of syncing the data
over to the secondary DC along with a copy of smb.conf and using that when
the primary DC/fileserver goes down. Would the clients know to use the new
fileserver: thinking about Kerberos here.
