I know I have sort of asked about this in the past months, and I have
seen a couple other inquiries.

Can someone who has successfully used GlusterFS as a maildir NFS
replacement with AFR post their configs to show how they did it, and
maybe post how their performance is?

Last time I messed with this (probably 2 months now) I had slow
performance and things would just crap out, so obviously I did not
understand something and probably had a bad config setup.

I have two nfs servers, 1 for our web cluster and 1 for mail, i would
love to merge the two of them and setup afr between them but I just
did not have any luck accomplishing this.

Hopefully this didnt get too long winded, but has anyone on this list
used glusterfs in a mail storage way with afr like described?
