[Samba] Reduntant Samba servers?

[adrian sender]

Hi Linus,

I have been using heartbeat + DRBD for serveral years now, very reliable and 
excellent setup. I highly recommend it. If you are having issues with 
heartbeat V2 try version 1.XXX; I still use version 1.

DRBD replicates the drives (raid1 over lan) very cool; heartbeat gives you a 
vurtual cluster IP.

Time to do some reading ;)

Hi,

I am trying to setup two redundant Samba Servers.

The file shares are on both servers and needs to be synced.
My best solution is to run an rsync between them every 5 min ?
Are there any smarter solution to this?

Another problem is how I could solve the kerberos authentication in the best 
possible way?
We have a Windows AD server and authenticate through kerberos.

If server1 is down I want to switch to server2 but use the same DNS / 
Computer name because all users have it mapped. It also saves the profiles.

I have tried to set up a DNS alias on the AD server's DNS and my idea was 
that I just could switch the alias to the server I want to use.

But that doesn't work because it is the alias name that tries to 
authenticate to kerberos and I then get: "Server not found in Kerberos 
database" on the kerberos server.


I hope someone has a smart solution to this?
