Very slow initial sync when creating HA - 1.4mbit?
Posted: Sat Jun 20, 2020 5:38 am
I had everything working in the trial version, now I am redoing everything with free.
I have two hosts, each with 4x NICs. Management (1gbit), heartbeat (1gbit), storage sync (10gbit), and final one for Hyper-V VMs(10gbit). Small boot partition, another 12TB for storage on the D: drive.
Management: 10.0.10.71 and 10.0.10.72
Heartbeat: 172.16.10.71 and 172.16.10.72
Storage sync: 172.16.20.71 and 172.16.20.72
Setting up a new 2-node HCA with free and getting VERY slow sync speeds when using CreateHA_2. Like 1.4Mbit between the hosts. I see in Task Manager the transfer is occurring over the 10gbit storage link. No speed difference with the firewall on or off.
When I set this up originally with the trial version, the sync was much faster. Did I miss something for the sync to be so slow? The only difference is I didn't set up cache on the original one, but not sure the arguments to not use cache. I did test with iperf3 and getting ~4gbit.
