Is it reliable to merge the system partition with an external SSD?

Operating System CasaOS

I’m running out of space on my ZimaBoard. I am wondering if anyone would lile to share her or his experience with merging the system partition with an external SSD? It seems to be the best solution but is it reliable?

If you want to move the Docker images and volumes, refer to:

Is this what you want?

Thanks, but this is not what I am looking for. My docker volumes aren’t that big.

I’m referring to the merge function in the storage interface of CasaOS. It is labelled beta and I was wondering if anyone had tried it.

Why not join our Discord channel and search for more?

That’s what I dix, too. But frankly, it wasn’t very helpful. It seems I can’t find someone who has tried merging.

I merged. Working as expected. No issues.

I finall got around to trying it. Thanks for the encouragement, @radioamerica7!

The process itself worked pretty easily. I added a new SSD using the y cable and merged this storage to my system partition. Casa OS volume manager still showed low storage for the internal memory chip but a lot of free storage for the system partition as a whole.

For some days, all went well, but the i started to notice some of the hickups I new from before when the system partition ran out of space: docker containers not starting properly, php errors, … I now even get a ‘no space left on device’ when I try to apt-get upgrade.

This is strange. The system partition as a whole still has several hundreds of gigabytes of free storage, but the internal chip now has ‘NaN undefined’ of free storage. I’ve seen this before, before i added the SSD and merged. But why isn’t the system now using the new storage more? If there is no space left on the internal memory, why not upgrade packages to the SSD? Or store docker containers there? I thought the whole point of mergkng was to have one big partition and the OS ‘magically’ figures out where to physically store the files.

I understand the merge functionallity is beta and this is not a rant. I just thought that maybe, someone here has experienced and solved this problem. I appreciate your help a lot.
