I unintentionally created a "Volume Group" when restoring to my boot SSD (did something the wrong way I guess - highly confusing for me)

I intended for the structure to be the same as the (no longer current) external copy.

I would appreciate advice on how to correct this without losing my data and system files and what exactly transpired. I couldn't choose the root/volume level when making the restore - had to choose either the "iMac191 SSD_512MB" or "iMac191 SSD_512MB - Data" and wasn't sure which one would be restored.

    Looks normal to me. Does your Mac boot correctly and with all your data visible?

  • I just booted from the external drive to compare the arrangement and sighed relief. It's exactly the same when booted from.

For the MacOS boot disk, this is normal. The "Volume group" for the boot disk consists of the base operating system and a "data disk". This is an intentional design to provide better protection from corruption (accidental or otherwise) in that most applications cannot write to the non-Data disk.

This design also generally allows for faster OS upgrades.
