Hi @ list

We have a problem with our pve-ovs setup...

The setup is based on: 
- Example 2

We use 7 pve nodes with ceph and 2x10Gbit/s ovs-bond uplink on all 
nodes. It works fine but suddenly... the ceph vlan interface update from 
mtu 9000 to mtu 1500 and ceph block request. The incoming packet size is 
than bigger as 1500 and ceph blocked requests...

Have anyone the same errors with this setup?
