tl;dr:
All cloud-vps instances listed in this email will be rebooted, by me, on
Tuesday December 2nd. This list includes several bastion hosts, where
existing logins, long-running jobs, or tmux sessions will be interrupted.
If you would like more control, you can hard reboot your instances
anytime in the next week and then I will not need to reboot them on the
2nd. Make sure to use the 'Hard reboot instance' menu option; a soft
reboot is not enough to clear the network settings.
details:
We have recently updated our virtualization hardware to slightly
increase the MTU[0], allowing normal-sized packet transmission[1]. This
change was necessary in order to resolve an issue with Docker containers
and, potentially, other issues not yet revealed. Certain VMs that
existed before this update now have an MTU size that doesn't match the
new size set on all hypervisors; this limits our ability to migrate
those VMs and perform other routine maintenance tasks.
A stop/start or 'hard reboot' of affected instances resets the MTU, as
it rebuilds the virtual network stack associated with the host. A 'soft'
reboot (or simply rebooting from within the OS of the instance) leaves
the network stack intact so does not resolve the issue.
If you want to reboot your VMs before Tuesday, there's no need to notify
WMCS staff. I'll re-run the report that lists affected VMs immediately
before rebooting, and a hard reboot will remove your VMs from any future
such report.
