Hello everybody,

I have a node where I installed nfs storage and I have a second nfs network storage. My node have a bond (4) with two nics and the other storage have a bond with 4 nics.

My oVirt engine runs as a VM on my network storage.

The bond on the node side is relative new, before I had this setup, the speed was good. But at the same time I also move my ovirt engine from a third server to the network storage.

My problem is now, when I move a VM disk from the network storage to the storage on the node, I have very pure speed. A VM with 140GB takes more then an hour to transfer.

When I make speed tests with iperf3 I got this speed:

- from oVirt to network storage: 20Gbits/s

- from network storage to node storage: 9.5Gbits/s

- from ovrit to node storage 9.5 Gbits/s

When I transfer a VM disk, iftop shows almost no traffic.

Have you an idea what is happen here?

Regards

Jonathan
