ZFS Pool - Drive is in Removed state, need to replace?

[TheePorkchopExpress]

Hello

I am new to ZFS and Proxmox, and have an error that I cannot fix. It is probably easy but my google searches have been unhelpful.

I have a R720 with 16 SAS 900gb drives. 2 for boot, 14 for data. My zpool with the "Removed" drive is called Data. I have tried various actions via CLI, screenshots attached. But because the drive is offline, it cannot be found. How do I either identify and/or replace that drive OR resolve the Removed status?

Lets see if that device is at all connected/working.

Post output for (in code-editor, using the </> in the formatting bar on-top of your reply):

lsblk -o NAME,serial | grep f7d64

If it returns nothing, then the system is not reading that device. There are two possibilities, either some cable is not properly connected/seated, or that drive has failed & will need replacing. (Rarely it has just over-heated, and may come back to life later).

Either way you will have to locate that disk physically.
As a good practice - you should label the devices with their serial numbers for easier identification later.

Maybe try enabling the LEDs for all present and responding drives: https://linux.die.net/man/8/ledctl . The one not lighting up should be the missing/broken drive.
