Apr 27 15:35:37 freetest kernel: Use `gpart commit zvol/zfsdata/vol` to save changes or `gpart undo zvol/zfsdata/vol` to revert them. And after gpart commit, it allows to gpart resize, growfs.. Exactly like I wanted. But I need to set freetest# sysctl kern.geom.debugflags=16 before resize actually works. And I did get a panic in one of the attempts, but with no keyboard to the console. So I had very little to act on, and needed to reset. I'll finish the test script and run it in a loop to see if the panic reoccurs. But so far so good. --WjW
