I had my docker img. file on a WD cache drive.

Decided to move it to my SSD which is an unsigned device. Pointed the path of the image to the new location and all my dockers were absolutely fine.

2 days later, while examining the logs I noticed strange messages:

Searched the forum and found out others has experienced the same problems. I understood that the docker.img file went bad and needs to be recreated.

My appdata fold is on the same unassigned device.

 

Could you please confirm the steps needed:

1. Stop the array;

2. Delete the old docker.img file;

3. Create new docker img.file;

4. Start the array;

4. Go to Community Applications;

5. Download the dockers I need;

6. The old paths and data of the dockers should be the same;

 

Thank you in advance.

 

p.s.

If you reinstall the docker containers from the Previous Apps section of CA, they will be reinstalled with your prior configuration intact.  If you reinstall them by searching in Community Apps and downloading again, they will be reinstalled with the defaults as a new installation.
