Hi Avati,
I'm using libfuse2 version 2.7.3-glfs10, the latest. The kernel module I'm
using is Debian GNU/Linux 4.0 default (kernel 2.6.18).
Regards, Jeroen

Jeroen,
what is the version of fuse (libfuse and kernel module) which you are
using?

Hi Krishna,
I forgot to mention that it's going to be a "p2p" cluster. It will consist
of two servers, mta1 and mta2, that will run both a server and a client
instance.
Again, thanks in advance.
Regards, Jeroen

Hi Krishna,
I'm sending my current configuration. I used about the same configuration on
the server side. The afr and mtaX-mailstore volumes where on the serverside
before, but that didn't enable fcntl locking.
Thanks in advance.
Regards, Jeroen
Below is my configuration:
---- glusterfs-server.vol ----
# Mailstore dataspace
volume mta1-mailstore-ds
type storage/posix
option directory /var/vmail_ds
end-volume
volume mta1-mailstore-ds-locks
type features/posix-locks
option mandatory on
subvolumes mta1-mailstore-ds
end-volume
# Mailstore namespace
volume mta1-mailstore-ns
type storage/posix
option directory /var/vmail_ns
end-volume
volume mta1-mailstore-ns-locks
type features/posix-locks
option mandatory on
subvolumes mta1-mailstore-ns
end-volume
# Export
volume server
type protocol/server
option transport-type tcp/server
subvolumes mta1-mailstore-ds-locks mta1-mailstore-ns-locks
option auth.ip.mta1-mailstore-ds-locks.allow *
option auth.ip.mta1-mailstore-ns-locks.allow *
end-volume
---- /glusterfs-server.vol ----
---- glusterfs-client.vol ----
volume mta1-mailstore-ds-locks
type protocol/client
option transport-type tcp/client
option remote-host mta1

end-volume
volume mta2-mailstore-ds-locks
type protocol/client
option transport-type tcp/client
option remote-host mta2
option remote-subvolume mta2-mailstore-ds-locks
option transport-timeout 10
end-volume
volume mta-mailstore
type cluster/afr
subvolumes mta2-mailstore-ds-locks mta1-mailstore-ds-locks
option self-heal on
end-volume

Jeroen,
Can you detail on the setup including the conf files?
Thanks
Krishna
