I tried just plugging it into ubuntu and it gave a password prompt for the luks "wrapper" like it was going to work, but then nothing.  Further attempts to see the XFS system inside were unsuccessful

 

I also tried mounting it on my unraid box as an unassigned disk with an array that has a matching password [as mentioned here](https://forums.unraid.net/topic/71501-encrypted-disks-read-on-external-computersolved/) but that was also unsuccessful.  UD sees it, but after clicking Mount it thinks for a second and then nothing happened.  Filling in the encryption password in UD settings also doesn't give any positive feedback or better result

Some mount attempts produce the luksOpen line, all of them produce the spin down line.  I've also tried attaching directly to SATA or through a USB adapter

 

 

EDIT:  Ok after posting I had an idea.  I put a trial unraid on another usb and mounted the encrypted disk as its own array.  This worked with no visible downsides so far, but surely there's a more normal way?

What you did should have worked.   The problem is to work out why it did not.
