Output of "fuser -m /dev/sda1" along with "ps auxw" taken right before the
unmounting
Version: unspecified (using KDE 4.5.0)
OS: Linux
For the last couple of weeks I have been having problems unmounting the hard
disk during shutdown/reboot of my computers (3 in total). Even though it may
seem impossible to be related to the KDE software, please read below to see why
I believe so.
I am using Kubuntu 10.04.1 64-bit with KDE 4.5.0 -- system is fully up-to-date.
I have disabled plymouth in order to see what is going on during
reboot/shutdown.
Every time I reboot, I get the following messages during the shutdown process:
[...]
Unmounting weak filesystems...
mount :/ is busy
will now reboot
[...]
Upon startup, I get the following:
[...]
[ 3.257417] EXT3-fs: INFO: recovery required on readonly filesystem.
[ 3.257512] EXT3-fs: write access will be enabled during recovery.
[ 4.299039] kjournald starting. Commit interval 5 seconds
[ 4.299140] EXT3-fs: recovery complete.
[ 4.303323] EXT3-fs: mounted filesystem with ordered data mode.
[...]
which also implies that the hard disk was not unmounted properly.
After a vane long googling around, I decided to do a fresh install.
I installed from scratch Kubuntu 10.04.1 which comes by default with KDE 4.4.2.
After the installation, I restarted the system plenty of times and unmounting
was successful every single time.
I then updated to KDE 4.5.0 and the problem appeared again! The system is clean
(nothing else installed on it except for what Kubuntu comes with) and it is why
I believe it is related to KDE 4.5.0. Please also note that this problem occurs
all 3 of my computers.
In my opinion, this should be considered a major bug since it can cause data
corruption or loss.
I attach a text file containing the output of "fuser -m /dev/sda1" along with
"ps auxw" taken right before the unmounting takes place. Please let me know if
you need more information.
Reproducible: Always
Steps to Reproduce:
Reboot/shutdown system.
Actual Results:
The devices are not unmounted properly.
Expected Results:
Devices should be unmounted properly.
