I have a cluster of instances in Google Cloud Platform that was accessible. I ran updates on a VM, then rebooted it. I have not been able to access the VM since. SSH fails, saying it cant be reached. I also cannot ping the instance. When I connect via the console port, it is flooded with martian source logs.
martian source x.x.x.x <affected machine> from x.x.x.x <some other ip>, on dev eth0 ll header: 42:01:0a:8e:00:05:42:01:0a:8e:00:01:08:00 Jul 11 20:07:40 <servername> kernel: __ratelimit: 3 callbacks suppressed
It is only affecting the machines that have been updated and rebooted. The ones that have been updated but NOT rebooted are fine (so far). I also checked the firewall-rules, and there is the default SSH rule.
I did find that if I clone an affected VM and give it a new OS disk, I can access it afterwards.
Any ideas? I am at a loss as to what to do with the ones that have been (and have not been) updated.
