[Samba] about samba failover

[Daniel Müller]

Drbd does work for Samba3!
DFs in Samba does not replicate data. It just does something like, if server
X/share is not there use server Y/share.

Hi
Sorry that this is just a 'me too' but I've been trying to get information
on failover too. This may give you some ideas other than clustering as I
believe that drdb will not wor with samba.

Evidently dfs can be used for this. I know it works great on windows DCs and
file servers but try as I may, I cannot get a single answer from either the
cifs nor samba lists on anything t do with it on samba. Here is what I've
tried so far:
