Hi, my STX 2.0 cluster is up and running (2x controller, 2x worker, 3x storage). but one of my worker have an problem, i can not fix it. after time (i do not know in detail, in most times over night) the data-network from all VMs are broken down, no connection over data-network are available any more. the other worker is running fine without any problems. if i live migrate the VMs from one to another worker and back again, the data-network is comming up and all is fine again. i do not find any logs that will explain this problem, any suggestions or hints for locking for? greez & thx, volker.
