So a small and quick story. At my job, I just inherited a VMWare server system that students use to do remote lab work last Friday. The guy before me's contract ran up and I was to take it over. I'm all good and great with this, except...
Our UPS failed over the weekend and it took down all of the server equipment for general IT operations and my recently inherited VMWare servers. Everything came up cleanly after booting everything back up (Servers, VMs, etc.)... Except for one apparently. The DHCP server VM got corrupted from an unclean shutdown.
I spent 3 hours trying to get that DHCP server back up and running, but gave up and spent only 15 minutes rebuilding the stupid thing in another VM. The original server is a goner cause the LVM partition is unreadable.
Moral of the story: If it's a server that houses only one service, just rebuild the stupid thing. Don't waste your time.
