which Filesystem would scale well in below scenario
 

Hey Fellas,

I would like to have your expert opinions and would love to know which Shared Disk Filesystem would scale well in case of Postfix+dovecot cluster where all the mailboxes will be kept on SAN or NAS.

a] GFS
b] NFS
c} GlusterFS
d] Or any other that you would want me to test?

I am gonna deploy cluster Linux postfix cluster which is a mailbox server as well and both the servers can access the shared Mail BOx.

Is it a VM, if so VMware likes NFS.

nah...its deployed on Physical servers.
