If g_mirror_taste encountered an error at g_mirror_add_disk, it might try to g_mirror_destroy the device with the G_MIRROR_DEVICE_FLAG_TASTING flag still set. This would wait on a worker to complete the destruction with g_mirror_try_destroy, but that function bails out if the tasting flag is set, resulting in a deadlock. Clear the tasting flag before trying to destroy the device. Test Plan: sysctl debug.fail_point.mnowait="1%return" kyua test -k /usr/tests/sys/geom/class/mirror/Kyuafile Reviewed by: markj Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D20744 |
