[ovirt-users] Re: Hosted-Engine constantly dies
This definitively helps, but for my experience the network speed is
really determinant here.Can you describe your network >configuration?
A 10 Gbps net is definitively fine here.
A few bonded 1 Gbps nics could work.
A single 1 Gbps nic could be an issue.
I have a gigabit interface on my workstations and sadly I have no option for upgrade
without switching the hardware.
I have observed my network traffic for days with iftop and gtop and I have never reached
my Gbit interface's maximum bandwidth, not even the half of it.
Even when reseting my bricks (gluster volume reset-brick) and running a full heal - I do
not observe more than 50GiB/s utilization. I am not sure if FUSE is using network for
accessing the local brick - but I hope that it is not true.
Checking disk performance - everything is in the expected ranges.
I suspect that the Gluster v5 enhancements are increasing both network and IOPS
requirements and my setup was not dealing with it properly.
It's definitively planned,
see: https://bugzilla.redhat.com/1693998>I'm not really sure about its time plan.
I will try to get involved and provide feedback both to oVirt and Gluster dev
teams.
