This is sound advice.

Best way is probably to use lvm and create multiple 2TB LVs with ext3.  
Disable auto-fsck and look at doing proactive online fsck. There was a  
post about a month ago on performing online fscks with snapshots.

For that kind of storage I might look at Solaris and ZFS though.
