How about Synology SHR? Do you need DSM to rebuild?
- AnIdiotOnTheNet 5y agoWhat SHR does is take the smallest disk size and create partitions of that size across all disks and raid them together, then take the second smallest disk size and create partitions across all disks with at least that much space and raid them together, then finds the third smallest, etc. [0] It's all still just lvm partitions and mdadm. > Do you DSM to rebuild? Depends what you mean. If a disk fails, I hot-swap a replacement in and press the volume rebuild button in the GUI.

- AnIdiotOnTheNet 5y agoAh, I see you've updated the question: > Do you need DSM to rebuild? I don't think so. I've never had to do it without DSM, but since it is just mdadm and lvm you should be able to connect all the remaining disks to and Linux box and run the appropriate mdadm commands to fix the array.
- aborsy 5y agoOk, thanks! Yes, I already figured out based on your previous response (and modified the question for others).
