Hi, I'm going to set up a new storage for our email users (about 10k). It's a network attached storage (Coraid). In your opinion, what is the best file system for mail server

Depends on what OS you have chosen, or if OS is not the limiter I would go

with ZFS.

Have you any performance comparison with xfs?

I'm running two imap servers. One with about 9k accounts and 3.5TB of storage, and another with 55k accounts and 2TB of storage with XFS, and I'm thinking about migrating them from XFS to ZFS but I'm concern about IO performance of ZFS. When we developed these two servers, I remember reading some zfs performance problems in comparison with xfs (I have lost the link) and that was the reason to finally use xfs, but now we are having problems with LVM snapshots and we also like some zfs features (like replication) so we are thinking about the change.
