I have made extensive load tests in the last few days and figured out
it's definitely a network related issue. I changed from jumbo frames
(mtu 9000) to default mtu of 1500. With a mtu of 1500 the problem
doesn't occur. I'm able to bump the io-wait of our gluster storage
servers to the max possible values of the disks without any error or
connection loss between the hypervisors or the storage nodes.
As mentioned in multiple gluster best practices it's recommended to
use jumbo frames in gluster setups for better performance. So I would
like to use jumbo frames in my datacenter.
What could be the issue here?
I would try with a jumbo frame setting of 4074 (or 4088) bytes.
Regards.
