Docker service failed to start

[robertomano24]

Hello,

 

I am not sure why, but docker service is failing to start all the sudden. I have never had issues, but reboots do not solve. I have posted diagnostics. Any advice? Previous threads have not been helpful in my case.

 

Thanks!

 

Edit: Diagnostics re-posted AFTER turning docker service back on. Also, logs indicated there is a read-only filesystem issue blocking the creation of the docker.img. This is new. Any ideas?

One of the cache pool devices had many errors (also there are also a few read errors on the other one) and it's failing to remove:

 

May 17 14:55:35 WhiteHouse kernel: BTRFS info (device sdb1): bdev (null) errs: wr 6420558, rd 28315, flush 142629, corrupt 0, gen 0
May 17 14:55:35 WhiteHouse kernel: BTRFS info (device sdb1): bdev /dev/sdb1 errs: wr 0, rd 20, flush 0, corrupt 0, gen 0

Best bet it to backup any cache data and recreate the pool, there are some recovery options here if needed, after recreation also see here for better pool monitoring.

@johnnie.black Thanks so much for this. I am a noob at Unraid, but not linux. I was able to get my files backed up for later, specifically from appdata. I am reading through some different forum posts now about recreating the pool, as it is not quite intuitive to me yet.

Hopefully this will get me back up and running!

Thank you again
