--- Comment #2 from Alan Somers <***@FreeBSD.org> ---
I encountered the same problem in a build based on stable/13 from last
September. But in my case "ctladm remove" did not work; it failed with the
same error. And since there are only two backends to choose from, I tried "-b
ramdisk" as well, which failed with the same error again. There was also one
remaining iSCSI session, connected to the faulty LUN, but "ctladm isterminate
-a" had no effect. I could only resolve the problem by rebooting.

$ sudo ctladm remove -b block -l 133
ctladm: LUN removal error: LUN 133 is not managed by the block backend
