Multiple Servers hosting same share

[Diego Remolina]

Cluster file systems are very slow as compared to plain ext3 or ext4. 
You may want to try and use something like drbd+heartbeat/crm+samba.

You configure two machines as master/slave, user drbd to do real time 
replication and control who runs samba on the master with crm. CRM is 
very cool as it can monitor your services. Let's say samba is running on 
node1 and for some reason it dies. CRM will do whatever is necessary to 
restart the service and if it cannot restart it in the current master 
node, it will migrate all services to the other node.

I am currently running a file server with samba 3.3.2, drbd 8.3 and 
heartbeat/crm. It is very nice. I tried upgrading to samba 3.3.3 but 
winbind was segfaulting, so will try 3.3.4 and see if that works. All of 
the above is running on RHEL 5.3
