  • Another real acronym with a funny story (maybe only to old geeks like me) is STONITH.

    Back when “high availability” meant two servers with shared storage and a “heartbeat” network connection, if one of the servers failed, the second one would notice there was no more heartbeat from the first and pick up the traffic so users would never know.

    However, if the servers lost the network connection, there’d be no way to tell if the other server was still running and if both continued accessing the shared storage, they could corrupt the application data. So each server could take over if it noticed the other wasn’t available by executing STONITH (Shoot The Other Node In The Head) basically sending a power down signal to the PDU, making sure the other node couldn’t corrupt data.

    My first cat was diagnosed as diabetic at 9 years old. He lived to 17. We tested him daily - which he didn’t mind at all - and usually ended up giving him one shot of insulin per day.

    He was the same old cat the entire time. I’m really glad we learned how to take care of him because now I’m not worried about having another diabetic cat. It’s just another thing to check on. Cats are just so accommodating when they know you’re taking care of them.
