- Create a new empty pool, using default params, named "test-pool"
- In console/shell, leave a login open that's using test-pool. The easiest way I found was simply to "cd /mnt/test-pool" in console shell
- In UI attempt to export+delete test-pool
Result - exception.
If the shell no longer uses the pool (easiest way: "cd ~") then export/delete doesn't throw an exception.
Debug dump taken but not attached as the situation is so generic that it should be trivial to reproduce.
