(I'm this person.) It so happens that the solar inverter I'm using right now doesn't provide a data connection that I could use to shut down the computers cleanly.

But I should also clarify that my long-running fsck isn't always the result of an unclean shutdown. There's something about my combination of iSCSI+crypttab+NFS that causes fsck to be run too often—even if I shut down the machine cleanly while the NAS is running, it usually decides to fsck when it comes back up.

Something to investigate next winter, perhaps.

Hi :) Thanks for the awesome write-up. I understand...I have a few devices in my house that resist all attempts at integration. I have considered doing something totally ridiculous like setting up a Raspberry Pi with a camera and machine vision software to watch the LED displays on these devices to glean status information. Silly, but...

Interesting about fsck running for unclear reasons. "What is it up to now?" is a valid question at multiple levels!

Glad you enjoyed it. :-)

Ha! I actually have a PoE camera pointed at the display of my UPS. Here's what it looks like right now: https://toroid.org/misc/ups-display.jpg

Notice that horizontal blank row of dead pixels halfway down the right side of the display? The one that makes "54.6" look like "51.6"? That gap defeated my naïve five-minute attempt to use image recognition to extract the battery voltage.

Whats up with the "[f]" in your grep command?

    grep '[f]sck'

It keeps the grep command itself from showing up in the output.

You could run a cheap/small UPS off your main stores maybe? That could possibly provide the signal and management
