Well friends I am happy again... I don't know if this "happiness" will last forever.. Only time will say... But now, with GlusterFS the VM hold still. Previously, with NFS, the iowait always high, near 15-20 %. Now, with Glusterfs, I am right now transferring more than 40GB from one server to VM and the iowait inside the VM hold 4,50 %... We will see what happens next.... Thanks for all help that I received from you guys! All my best!
