I've got a 3TB (7 x 500GB w/ hot-spare) array on an areca board in amd64.
Under 5.4-R I could have >1TB filesystems without an issue. I recall not
having problems with 6.0-BETA5 too.
However, 6.0-R gives me a tragic:
/dev/da0s1d 723G 54G 611G 8% /home
Certainly not what I was hoping for.
I've tried both i386 and amd64 releases.
Especially since that apparent limit is much smaller than 1TB.
Dmesg Below.
