[Dovecot] Best Cluster Storage

[Henrique Fernandes]

I use ocfs2 with 3 dovecots. one only for mailman.

We have problens with IO. Have about 4k active users.

We are now testing more ocfs2 clusters, becasue one of yours theorys is that
iff all mail resides in only one ocfs2 cluster, it takes too long to find
the file. ocfs2 i guess does not support index. using ocfs2 1.4

So now, we are gettins smallers luns from your storages and mounting 3 ocfs2
clusters that way we think the DLM will work better.

Sorry if i did not answer your question.

Anyway, we had some tests with NFS and it wasn't good also. We prefere
sticky with ocfs2.

We are balacing with IPVS, not using dovecot director.

How many users will have ?

oh, we also use xen. Every host on mailsystem is an xen vm.
