only win6 remains to be up and it will come any moment.
Ok what happened, something made the node server to reboot (still checking that in logs), on reboot we had added a hotswap non raid disk to the server for some non critical extra space on local storage, this hotswap drive was detected on boot and set as the first boot device, no OS on it so it died.
I am still researching why the KVM access was also down as this should have been resolvable remote.
And with that win6 also just came up.
We will be checking this and working to prevent such in the future.
