Hello,
A couple of times this week we have had the errors below on a host in a cluster:
'vSAN Health Alarm 'Hosts with connectivity issues'
'vSAN Health Alarm 'Stats master election'
We find the NICs look ok on the host and switches, but VMs ping times become irregular, so 1ms for a few swconds then in the 100s. What we have to do is migrate the VMs off the host to another, put into maintenance mode and reboot then the host is fine again for a few days.
The only job running in the background on the cluster is a vSAN rebalance where we have added 2 more hosts, this rebalance can take 24-48 hours.
This is ESXi 6.7 6.7.0, 10764712.
What host logs should I be looking at? I guess we may need to get to update 3.
Thanks
