Hi All,

 

For some reason, Docker keeps crashing. After reviewing the system logs, the main thing that stands out is:

 

Oct 6 03:41:04 HS kernel: BTRFS error (device sde1): block=1077952512 write time tree block corruption detected Oct 6 03:41:04 HS kernel: BTRFS: error (device sde1) in btrfs_commit_transaction:2466: errno=-5 IO failure (Error while writing out transaction) Oct 6 03:41:04 HS kernel: BTRFS: error (device sde1: state EA) in cleanup_transaction:1964: errno=-5 IO failure Oct 6 03:41:05 HS kernel: loop: Write error at byte offset 992399360, length 4096.

 

I'm assuming the device sde1 is my main cache drive, since the path is /dev/sde in system devices, so could it be a faulty drive?

 

I attached my diagnostics. I'll keep digging around and post a solution if I find one.

 

Thanks!

 

**Edit**

I cleared my logs and stopped / restarted docker. For some reason the docker.img is in use and terminates the start.

The pool filesystem went read-only, and this error:

 write time tree block corruption detected

can indicate a RAM issue, so good idea to run memtest.

 

There are also macvlan call traces, change the docker network to ipvlan.

Set the network to ipvlan and memtest is running. Memtest is on its 3rd pass with 0 errors.

So I ran memtest for a day or so and nothing failed. However, after changing the docker network to ipvlan and removing a potentially faulty array hard drive, everything is good again.
