That’s kind of what I figured, my biggest concern at this point would be how difficult it is to move the lvm volume to a different device. It seems pretty straightforward if you have a working setup, but from what I’m seeing in my research is silence if your device (server, etc.) dies and you need to move those volumes to another. I’m finding guides on either recovering from corruption or lost metadata, or transferring from one working device to another. Nothing I can find about importing a fully functional lvm to a new device if it hasn’t been exported.
I’ll be able to do that later today, so I guess I’ll see what happens if I do. Better to try it out now when it isn’t critical.







I did not find just moving the drives to work. There were some other issues that I came across that might have a part to play in it, I made the lvm and filesystem on an RPI5 running OMV and moved it to a rock3c running OMV from an armbian install. Turns out there’s a pagefile size mismatch between the two that prevented mounting the btrfs filesystem. But I still wasn’t able to get the rock3c to recognize the VG or that there were new PVs attached without exporting first. So perhaps the armbian install isn’t modern enough to automatically recognize it.
I didn’t expect learning new things about btrfs to be the outcome of this little experiment, but I guess that’s just how things work.
