March 16, 20206 yr This is weird and I know it but if any one can help I'd appreciate it. I'm getting high retr when iperf3 from my unraid r720 to my unraid r710 constantly: Quote 4] 325.00-326.00 sec 112 MBytes 937 Mbits/sec 0 235 KBytes [ 4] 326.00-327.00 sec 106 MBytes 890 Mbits/sec 1468 195 KBytes [ 4] 327.00-328.00 sec 97.7 MBytes 819 Mbits/sec 1273 195 KBytes [ 4] 328.00-329.00 sec 97.8 MBytes 820 Mbits/sec 1121 195 KBytes [ 4] 329.00-330.00 sec 101 MBytes 850 Mbits/sec 1270 195 KBytes [ 4] 330.00-331.00 sec 112 MBytes 938 Mbits/sec 0 195 KBytes [ 4] 331.00-332.00 sec 112 MBytes 937 Mbits/sec 0 195 KBytes [ 4] 332.00-333.00 sec 111 MBytes 930 Mbits/sec 0 195 KBytes [ 4] 333.00-334.00 sec 110 MBytes 926 Mbits/sec 125 189 KBytes [ 4] 334.00-335.00 sec 98.1 MBytes 823 Mbits/sec 1914 195 KBytes [ 4] 335.00-336.00 sec 98.9 MBytes 829 Mbits/sec 2105 195 KBytes [ 4] 336.00-337.00 sec 102 MBytes 852 Mbits/sec 503 195 KBytes [ 4] 337.00-338.00 sec 104 MBytes 876 Mbits/sec 105 195 KBytes [ 4] 338.00-339.00 sec 100 MBytes 840 Mbits/sec 708 195 KBytes [ 4] 339.00-340.00 sec 99.0 MBytes 830 Mbits/sec 783 195 KBytes [ 4] 340.00-341.00 sec 98.7 MBytes 828 Mbits/sec 578 195 KBytes [ 4] 341.00-342.00 sec 100 MBytes 841 Mbits/sec 1344 195 KBytes [ 4] 342.00-343.00 sec 99.4 MBytes 834 Mbits/sec 377 195 KBytes [ 4] 343.00-344.00 sec 100 MBytes 842 Mbits/sec 1137 195 KBytes [ 4] 344.00-345.00 sec 101 MBytes 845 Mbits/sec 317 195 KBytes [ 4] 345.00-346.00 sec 98.6 MBytes 827 Mbits/sec 1618 195 KBytes [ 4] 346.00-347.00 sec 99.8 MBytes 837 Mbits/sec 537 195 KBytes [ 4] 347.00-348.00 sec 101 MBytes 850 Mbits/sec 733 195 KBytes [ 4] 348.00-349.00 sec 98.0 MBytes 822 Mbits/sec 1570 195 KBytes [ 4] 349.00-350.00 sec 98.0 MBytes 822 Mbits/sec 2215 195 KBytes [ 4] 350.00-351.00 sec 100 MBytes 840 Mbits/sec 466 144 KBytes [ 4] 351.00-352.00 sec 101 MBytes 846 Mbits/sec 977 195 KBytes [ 4] 352.00-353.00 sec 99.2 MBytes 832 Mbits/sec 2081 191 KBytes [ 4] 353.00-354.00 sec 100 MBytes 839 Mbits/sec 408 195 KBytes [ 4] 354.00-355.00 sec 96.9 MBytes 813 Mbits/sec 2085 195 KBytes [ 4] 355.00-356.00 sec 98.4 MBytes 826 Mbits/sec 1922 195 KBytes [ 4] 356.00-357.00 sec 98.7 MBytes 828 Mbits/sec 990 195 KBytes I thought I narrowed it down to my unifi video docker (when that docker is stopped the retr's stop); however, I get retr's also when during an install or uninstall any dockers. After the install is complete it goes back to zero (when unifi-video container is stopped also). When playing videos from plex docker (710) which accesses library files from the r720 there are no retr's (with the unifi video docker stopped). I tested all the camera's individually(disconnecting), updated to :beta, changed my POE to inline for testing. If I iperf3 my 10gb connect between my r710 and r720 its fine. I also tested iperf using different 1gb nic ports from the r710 to r720 and still get retrs.

I've been messing around with network setting, dockers, hardware. I've lost a little focus and I'm not sure where to go now. I'm tempted just to reinstall the unifi-video and ignore all the retr's. Would that be so bad? I'm not an IT person and it could be a simple error I've made in playing or setting up my homelab. I'm not including any info on my r720 I've spend a lot of time looking at it also but I believe its somehow network / docker on the 710 related but I don't know. r710-diagnostics-20200316-0957.zip
March 16, 20206 yr Author So I thought I'd just solve this the old fashioned way... I uninstalled the unifi-video docker from the r710 and install it on my r720. I get not more retr's from the iperf client from r720 to the iperf3 server on the r710. BUT now I get retr's when I -R (or reverse the packets) WTF? My r720 server is fairly clean but I get the same issue on a completely different server with different (newer) hardware. I might just create a VM just for the unifi video.
