[Gluster-devel] Best performance glusterfs v. 3.0.0 and samba

[Roland Fischer]

Hello,

i have some troubles with glusterfs v.3.0.0 and samba.
Have anybody experience with gfs and samba? Maybe my config files oder 
tuning options are bad?

we use xen 3.4.1 and glusterfs3.0.0 and client-side-replication.

One domU which is running on glusterfs should release another gfs-lun 
via samba. But the performance is bad.
