ledmon - Identify Disk Drives


On a server with many drive bays (hard drives, HDD, SSD) it can be hard to find which one the software is referring to. Use “ledmon” to identify the drive using the built-in LED’s


Install ledmon (it’s called that in Ubuntu repos)

Identify your drive: sudo ledctl locate=/dev/sdb

You should see the LED begin to flash

You can turn off the locate when done with: sudo ledctl locate_off=/dev/sdb
