So it's really necessary to build reverse - geli on top of glabel. The label is only created once. After that, it will be present when the .eli device is created. It's possible there is a misunderstanding about what exactly is going on here, and a concrete example would help.

But here an example: 1. Insert one disk 2. Create geli and glabel there 3. Pull out that disk and insert it again in random order with hundred of other disks 4. Try to find where geli is located So I can say again - glabel inside geli doesn't make any sense in any situation. But geli inside glabel makes sense almost always. > > It's possible there is a misunderstanding about what exactly is going on here, and a concrete example would help.
