I have been having issues with docker lately.
Upon reboot it does not auto start.  docker file at 75% full
Manually starting has worked once per boot.  shutting down docker and re-starting does not work. failed to start error.

Last night docker service shut down.
Reboot machine.
Docker wont start, even manually. 

 

I just got a message from "fix common problems" it says my cache is mounted read only?!?

Unraid 6.12.4

is my cache drive failiing?
I found a similar issue with another user, his drive was dying.

 

EDIT:

i just got back from the store and installed a new 2tb nvme.

not sure how to do a cache swap though.
spaceinvaderone video on the subject requires docker working and using krusader.

 

EDIT:
6 hours later
I get a failed disk error on my parity 0 drive
rebooted, cant start array in maintenance mode.
more diags attached.

EDIT:
purchased an NVME its mounted as unassigned.
currently cp -Rfvp /mnt/cache/* /mnt/disk7/CACHE-BACKUP/

My cache was bad.

purchased a new drive at store

 

started array with VM OFF / DOCKER OFF

 

terminal

mkdir /mnt/disk7/CACHE-BACKUP/
cp -Rfvp /mnt/cache/* /mnt/disk7/CACHE-BACKUP/
wait

stop array. remove old cache drive. start array.

stop array. add new cache drive. start array.
cp -Rfvp /mnt/disk7/CACHE-BACKUP/* /mnt/cache/

start array.  enable docker, enable VM
