Hi all,
We have quite a few servers hosted by a VPS provider, running FreeBSD 10.2.
We recently had a group of 28 servers receive a hard reset by the hosting provider, and 11 of them failed to boot afterwards. The hosting provider says the only thing that changed was the removal of an old eVPN interface and connection of a new one, but we don't really know if anything else happened.
All machines had been gracefully shut down only minutes prior and booted fine, then the hard reset was performed, and now they are stuck in a kernel panic reboot cycle.
We've tried booting with a custom iso mounted, and running fsck but to no avail. We've also had the instances moved to a new host machine to rule out hardware issue and it made no difference.
Any ideas of where to go from here? Any idea what could cause the instances to have this general protection fault all of a sudden? Or even how to avoid something like this happening again in the future, as hard resets can obviously happen from time to time. We've had plenty of hard resets before though over the years and have never seen this happen before.
Any help greatly appreciated!
Rob
