Local file system not properly unmounted during shutdown
- by bernhard
I have a file system with two HDDs and several partitions mounted separately locally.
/root, /home, /usr, /var, /local/share , /home/bernhard/fotos/bilder, /backup are on separate partitions and are all ext3.
During unmounting the message "unmounting local file system" does not appear any further and when booting all partitions but the root partition have to reload the journal, which indicates improper unmounting. The root partition and /usr are on sda, the others on sdb or further usb-mounted devices. the only partition unmounted w/o problem seems to be the root partition on sda4.
I wonder whether the script to umount all devices has a "wait for success" loop or that the script itself got corrupted. However, yesterday I upgraded to 11.04 and the error persists.
pmount does not look to be appropriate since the device are not hotplugged but simply mounted during system start. Obviously mounting /usr and afterwards /usr/local/share as well as /home and later /home/bernhard/fotos/bilder presents problems for umount; the devices may be busy und thus not properly unmounted.
Does anybody have an idea for a script to organize unmounting in an ordered way? How to wait for unmounting of the secondary mount? Do you know as well where to place such a script that it will be used instead of the original umount command?
Could be a general solution.
