[Gluster-users] Missing files with unify 2.0.0rc1

I can reproduce the problem with this more simple configuration file
and using just one server.
On the server side:
volume brick
type storage/posix
option directory /homes/davinci/filipe
end-volume
volume ns
type storage/posix
option directory /homes/ns
end-volume
volume server
type protocol/server
option transport-type tcp
option auth.addr.brick.allow *
option auth.addr.ns.allow *
subvolumes brick ns
end-volume
On the client side:
volume b1
type protocol/client
option transport-type tcp
option remote-host michelangelo
option remote-subvolume brick
end-volume
volume ns
type protocol/client
option transport-type tcp
option remote-host michelangelo
option remote-subvolume ns
end-volume
volume unify1
type cluster/unify
subvolumes b1
option namespace ns
### ** Round Robin (RR) Scheduler **
option scheduler rr
option rr.limits.min-free-disk 10% # Don't drop free space below %
option rr.refresh-interval 10 # Check server brick after 10s.
end-volume
I will see if I can discover any pattern on the missing files.
