All of a sudden got plex down notification. So logged on to my dashboard and noticed all the dockers are stopping. 

 

Checked error log and saw this

I have attached diagnostics. Is the docker.img the issue all my drives are XFS so assuming it's has to be the docker?

Solved

Just noticed on the docker tab
One or more paths do not exist (view)

So checked the cache SSD and that's online and accessible

So I'm guessing the next step would be to create a new docker.img with a new name?

If course would like to get to root cause too.

I think the SSD is dead! But it's showing online but nothing seems to be available in there and appdata share is missing.

Before I go into full panic mode. I am pretty certain I have appdata backed up atleast weekly to my array.

But still not sure what is going on as I'm on my mobile and have to vpn on to server.

Appdata share seems to be missing. If SSD is corrupt surely it should still be visible under shares tab?

Looks like it just dropped offline.  Reseat the cabling.

Shut down, unplugged and replugged SSD.

Unraid showed it as unmounted, after remount I started docker.

All sorter [emoji106]

Cable wise everything looks fine, might just order another SATA cable just in case.

Just got the following alert

Event: Unraid Cache disk SMART health [199]
Subject: Warning [sERVER] - udma crc error count is 1
Description: CT1000MX500SSD1_1910E1EE9FE0 (sdb)
Importance: warning

Pretty sure this related to bad sata connection. I have a replacement coming from amazon tomorrow.

It's just my luck when I need a spare cable I can't find it [emoji23]
