Hi everyone! I have 4 nodes connected via 2 Ethernet 10Ge adapters in cluster. Adapters combined to OVS Bond and OVS bridge is created. I have 3 vLAN - management, cluster and ceph.
Master Plan
I created 2 pools - SSD and HDD via crushmap https://paste.ubuntu.com/p/jcDTZQMp5w/
When I test iperf speed everything is OK (10G)
Now I tried to create VM, with virtio disk on HDD pool. First test was good ~500Mbps. Network showed ~2,5Gbps. Then I changed MTU to 9000 and random read\write speed is ~150mb\s and network works on 100Mbps. Then I changed MTU to 1500 and random r\w is ~400mbps.
What I am doing wrong?
