just restarted my array as i'm swapping a lower density driver for a higher density drive. when i restarted the array now i cannot start Docker

 

I see the following in my logs

Mar 12 09:02:11 Enterprise emhttpd: shcmd (9298): /usr/local/sbin/mount_image '/mnt/user/system/docker/docker.img' /var/lib/docker 30

Mar 12 09:02:11 Enterprise emhttpd: shcmd (9298): exit status: 1

 

I tried performing a btrs scrub which completed without error and this still doesnt resolve the issue.

 

I assume the problem is a corrupt docker.img on in my cache pool and i will probably need to recreate my docker.img file but i would like to avoid this if i can given the work required to re-create all my docker containers and getting them all configured as before.

 

Any pointers or help would be greatly appreciated ... thank you in advance

Delete and re-create the docker image.

Thank you ... this helped me understand the persistence of the docker config. 

 

Note to others, if you have any custom docker networking this is not persevered. you will need to recreate your networking prior to installing the applications
