Zfs for data, vms, lxc, file server.
Ext4 for basically root partitions, maybe ufs on the non-jailed freebsd.
Old policy, separate data and OS so you can switch quickly, had it since dos and never really switched.
Zfs is perfect but heavy, especially the arc so try not to wave it at everything. Ext4 is good enough for anything where I really don't care about integrity.
Tried btrfs but zfs is awesome because when I'm done I can always send a snapshot from my workers to the main fileserver with zfs-send and keep it around. Zfs-send/receive really change the game, as does zfs's trusted raid and zlog/l2arc which makes spinning rust fly.
