Hi, Our parallel root checks look already nice on the first view. On the second view they fail the stress test, at least on my system. Mostly umounting fails due to "device in use" and similar. For me it seems that "udevadm --settle" has no effect sometimes. Very often the label, utab, context and recursive mount tests make problems. I've made sure that udisks and similar devils are not running. One may try to use my script sippet below to run a loop until it fails. You should remove the "sort" from run.sh to get more failures: patch tests/run.sh ----- printf "%s\n" ${comps[*]} | - sort | xargs -I '{}' -P $paraller_jobs -n 1 bash -c "'{}' \"$OPTS\" || echo 1 >> $top_builddir/tests/failures" ----- #### ultest.bash ### ## Attention, using sudo" i=0 while true; do echo -e "\n#### run test loop: $((++i)) ####\n" ## select any interesting subset of all tests and shuffle mytests=$(git grep -l "^ts_skip_nonroot$" -- tests/ts/*/ \ | sort --random-sort | sed "s@tests/ts/@@") test -n "$mytests" || { echo "empty tests!?"; break; } time sudo ./tests/run.sh --parallel=30 --exclude="some-bad-tests" $mytests \ || break done echo -e "\n#### bad run: $i ####\n" ############### cu, Rudi -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
