drbd has had support for several Terabytes for a while and the old
limitations were overcomed by using the flexible-meta-disk option in the
configuration file.
I think the old limitations were 4TB in 0.7 and then it went up to 8TB
or even 16TB in 0.8 with the regular metadisk option.
For what is worth, I have a 12TB and 4TB drbd partitions which work just
fine, so 1 or 2TB for you should be fine.
/dev/drbd0 12T 1.9T 10T 16% /export/data
/dev/drbd1 4.0T 3.9T 128G 97% /export/scratch
Since you will be handling e-mail I would strongly recommend that your
backing storage is configured in raid 10 as that would give you the best
writing performance and e-mail implies lots of writes.

Hi all,
I am in the process of implementing Zimbra OPen Source with heartbeat
and Heartbeat. I am new to this DRBD concept. We have around 1 Tb of
users mail data. We have EMC SAN storage. So planning to make 2 LUNS
each of 2 TB and mounting the two LUNS to two differentn servers.
Will DRBD solution is suitable for mailboxes of this much size. please
suggest.
Thanks
