My current linux system init uses systemd and udev, with 'automount.rules' and 'mount.sh' in /etc/udev/, to manage device. But owning to MountFlags=slave, hotpluggable media (e.g., /dev/sda1 ) can be mounted again in host, whereas can't be formatted by mkfs.ext4 in host with error message '/dev/sda1 is apparently in use by the system; will not make a filesystem here!'. In your reply, you told me to invoke "systemd-mount" from udev rules. Do you mean that I should replace /bin/mount with /usr/bin/systemd-mount in mount.sh, or add "RUN+='/usr/bin/systemd-mount $env{DEVNAME}'" to automount.rules? 1） I replaced /bin/mount with /usr/bin/systemd-mount in mount.sh. /usr/bin/systemd-mount $DEVNAME "/run/media/$name" it prompted that systemd[1]: dev-sda.device: Job dev-sda.device/start timed out. systemd[1]: Timed out waiting for device dev-sda.device. systemd[1]: Dependency failed for /run/media/sda. systemd[1]: run-media-sda.mount: Job run-media-sda.mount/start failed with result 'dependency'. systemd[1]: Dependency failed for File System Check on /dev/sda. systemd[1]: <a class="moz-txt-link-abbreviated" href="mailto:systemd-fsck@dev-sda.service">systemd-fsck@dev-sda.service</a>: Job <a class="moz-txt-link-abbreviated" href="mailto:systemd-fsck@dev-sda.service/start">systemd-fsck@dev-sda.service/start</a> failed with result 'dependency'. systemd[1]: Startup finished in 16.692s (kernel) + 1min 32.605s (userspace) = 1min 49.298s. systemd[1]: dev-sda.device: Job dev-sda.device/start failed with result 'timeout'. ... in /var/log/syslog. </pre> </blockquote> <pre wrap=""> Try systemd-mount --no-block ... _______________________________________________ systemd-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:systemd-devel@lists.freedesktop.org">systemd-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="https://lists.freedesktop.org/mailman/listinfo/systemd-devel">https://lists.freedesktop.org/mailman/listinfo/systemd-devel</a> </pre> </blockquote> </body> </html>
