To start, I have no parity. My parity drive arrives tomorrow and I will start a parity build. I bought some new drives and one was throwing errors so I am sending it back. I shutdown all my docker and other services and rsync'd all the files off the drive to other drives in the array. I was able to drop the drive to no issue and do a new config and everything is there except the dockers. Do I need to do something special to have it recognize my older docker stuff or change a pointer as the system files are on disk 9 now instead of disk 7? I have a backup of the system folder and I could re-mount the old drive if I needed to as I did not wipe it. How do I get my dockers back? Thanks for the help.

Assuming your dockers were pointing to /mnt/disk7, you will need to change them to /mnt/disk9.

 

Alternatively, consider using /mnt/user if you are on 6.2 or higher. Don't do this on lower versions. With 6.2, they finally fixed hard links or whatever. If you use /mnt/user, then regardless of disk change, docker paths will not change, ever.

 

 

EDIT: To clarify, if your path was

 

/mnt/disk7/appdata/(dockernamehere)

 

then you will need to change it to

 

/mnt/user/appdata/(dockernamehere)      -----> ONLY FOR 6.2

 

or

 

/mnt/disk9/appdata/(dockernamehere)      -----> not preferred because it's tedious to change around

I figured it out.

It looks like docker made another system folder on another disk and was referencing that file over the one I wanted it to. Looking through each disk I saw two that had a system folder with actual data in them. I renamed one to systemOLD and then deleted the contents of the other. I then copied the fodlers and files "docker and libvirt" into the system folder. I did all this with docker off and the array running. I then made sure there was only one system folder on the disk by looking at each disk manually. Once I was sure I only had one system folder and it had my docker files in it I started docker back up. Now all my stuff is showing up and working.

 

Steps easier to read. "I have no parity not sure how this works with one"

1. Search all disk for system folder ex. "/mnt/disk8/system" "/mnt/disk7/system" , in my case disk 7 and 8 each had one.

2. Make sure docker is turned off, settings->docker->enable docker no->done

3. rename one of the system folders to systemOLD , You may have more than one rename all but one to systemOLD

4. Copy your know good system folder over top of the system folder you did not rename.

5. Start docker back up and confirm everything is working. settings->docker->enable docker yes->done

 

This worked for me and may work for you. Good Luck
