I use drbd in active/active mode in production with GSF on a Fedora Core
5 to share /home

My setup is :
2 nodes with 6 SCSI hard drive in hardware RAID 5. (HP DL 385)
Fedora Core 5 / vmlinuz-2.6.17-1.2157_FC5smp
lvm2 2.02.01
drbd 8.0pre4
gfs 6.1.5

This configuration works well because the files reached by the nodes are
in different directories, then the distributed lock manager (DLM) is not
a bottleneck.

When file are in the same directory, I see very long delay until
completion of file operations. Then I'm not sure drbd in active/active
mode is good for a mail spool. I hope GF2 will be better and faster.
