Hi list. On shutdown I have Buffer I/O error on device dm-... because the truecrypt disk is unmounted later than the usb disk containing the truecrypt image. I think this happens, because 1) systemd can't figure out the correct mount dependencies 2) umount is called with the force flag --------- There are workarounds specially for truecrypt, but why not solve the problem entirely?
1) I think the mount dependencies can't be made 100% reliable. systemd should use the combination of them and /proc/mounts, but only as a HINT In my case /proc/mounts contains the right order. 2) Instead of force umount, systemd should first try to umount everything gracefully, and if at least one mount point was unmounted successfully, then retry. Only if all mounts are busy, systemd should force umount the first candidate and then repeat the graceful umount for others. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
