Yes, I'm seeing this unexpectedly fail with EBUSY (errno 16) instead of
ENOTSUP. This was definitely caused by the hot spare work, and it's my
fault for not running ztest more rigorously. I'll file a bug and take a
look. For now, you can change (in ztest.c):
if (error == EOVERFLOW)
expected_error = error;
To:
if (error == EOVERFLOW || error == EBUSY)
expected_error = error;
I've been able to run this way for 10 minutes, with the 'rarely ->
always' change.
Sorry about that,
