After almost half a century, I'm still doing it... (lemmy.sdf.org)

So I'm working on a server from home.

I do a cat /sys/class/net/eth0/operstate and it says unknown despite the interface being obviously up, since I'm SSH'ing into the box.

I try to explicitely set the interface up to force the status to say up with ip link set eth0 up. No joy, still unknown.

Hmm... maybe I should bring it down and back up.

So I do ip link set eth0 down and... I drive 15 miles to work to do the corresponding ip link set eth0 up

50 years using Unix and I'm still doing this... 😥

A few months ago I accidentally dd'd ~3GiB to the beginning of one of the drives in a 4 drive array... That was fun to rebuild.

    Your 4 drive raid5 array, right?

    Right?!

    I wish.

    It was a bcachefs array with data replicas being a mix of 1,2 & 4 depending on what was most important, but thankfully I had the foresight to set metadata to be mirrored for all 4 drives.

    I didn't get the good fortune of only having to do a resilver, but all I really had to do was fsck to remove references to non-existent nodes until the system would mount read-only, then back it up and rebuild it.

    NixOS did save my bacon re: being able to get back to work on the same system by morning.

    Like 3 weeks ago on my (testing) server I accidentally DD'd a Linux ISO to the first drive in my storage array (I had some kind of jank manual "LVM" bullshit I set up with odd mountpoints to act as a NAS, do not recommend), no Timeshift, no Btrfs snapshot. It gave me the kick in the pants I needed to stop trying to use a macbook air with 6 external hard drives as a server though. Also gave me the kick in the pants I needed to stop using volatile naming conventions in my fstab.
