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!
