Setting up my server as a newbie some years ago, I did not have the ability to purchase more then one 8TB hard drive. Outgrew that rather quick and now I have two additional 16TB drives, in a Just A Bunch Of Disk configuration, mounted to different /mnt mount points. I know this is not ideal, but lacking the ability to expand further or buy new drives for a new zfs pool and transfer, I don’t have much of a choice but to wipe the drives, set up a zfs raid and re-download everything.
I have everything set up in docker-compose files, so I’m pretty sure I just need to keep those and the folders where the configs are, modify the compose files with the new file structure and… I am unsure where to go from here. Will everything start being grabbed as soon as my dockers spin up? Is there an additional procedure I need to do to make sure I don’t wipe my existing config files with blank empty ones? Is there an easier way of doing this?
Yes, as long as you update the volume mounts, the change will be invisible.
But you should have a backup anyway.
