Cache became unmountable


Go to solution Solved by JorgeB,

Recommended Posts

I'll start by saying I've had this server for about 3 years now but have almost no clue what I am doing. I've built everything by following youtube videos and articles. I have 0 Linux experience and use the GUI 100% of the time.

Running Version 6.12.4

 

Woke up this morning to a notification on my phone from Plex that a drive is corrupt. Went on the server GUI, didn't see anything so did a reboot. upon reboot my cache drive(M.2 Drive) says this:

Quote

Unmountable disk present:
Cache • Samsung_SSD_970_EVO_Plus_1TB_S6S1NG0R651236W (nvme0n1)

Quote

CacheSamsung_SSD_970_EVO_Plus_1TB_S6S1NG0R651236W - 1 TB (nvme0n1)40 C118180btrfsUnmountable: Unsupported or no file system

 

On my plex server some of the stuff works perfect and some has no pictures and cannot play the video as it says not found. But I don't see any issues with my drives? All of my dockers seem to be missing, assuming all that info is on the cache drive.

 

What's my best option here and easiest to follow for a Linux novice?

It's logged as a device problem, and SMART confirms it, you will nee to replace the device.

Thanks, what's the easiest way to get the data off this device to copy onto new drive? Or is that not an option?
