ubuntu 20 VM - SSD emulation is recognised as HDD

Then there is the question why your 10TB thin-provisioned virtual disk actually consumes 13TB of space.
 
Correct, I thought it was due to the lack of TRIM. Obviously it's not, I checked my other ubuntu VMs and it pretty much matches with 16K block size and df -h. However, the largest VM has this space problem, which I don't really understand. It seems to boil down to destroying and reinstalling.

rpool/data/vm-103-disk-0 volblocksize 16K default
