Do you have a habit of checking your disk health? I check mine every month to prevent disk corruption and data loss.

If you are interested in smartctl, here is a demo: https://x-cmd.com/1min/smartctl

Smartmontools on Debian sets up a continuous monitoring daemon so you can get an email if any monitored disk has errors.

/etc/default/smartmontools

#enable_smart="/dev/hda /dev/hdb"

Thank you for sharing, I like this feature.

smartctl recently helped me nail down some nasty slowdown issues with Proxmox running on an Intel NUC. the problem turned out to be that the box was running really hot!

  smartctl -A /dev/<device> | grep 'Temperature:'

i bought a small USB-powered clip-on fan, plugged it into the NUC and instead of ~75C the NUC is now running at ~32C and speed is as-expected.
