Max, as I've understood, "no splash" doesn't disable plymouth. Some people
suppose that the freezed plymouth is the cause:
https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1019347
I've decided to find it out and totally purged plymouth from system. But that
didn't help.
So, what do we have now?
I've modified /etc/init.d/umountroot script (part at 86 line):
=========================
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
do
mount $MOUNT_FORCE_OPT -n -o remount,ro -t dummytype
dummydev / 2>/dev/null \
|| mount $MOUNT_FORCE_OPT -n -o remount,ro
dummydev / 2>/dev/null \
|| mount $MOUNT_FORCE_OPT -n -o remount,ro
/
ES=$?
# [ "$VERBOSE" = no ] || log_action_end_msg $ES
log_action_end_msg $ES
if [ $ES -gt 0 ]
then
LOG=/mega-log-`date +%s`
echo "`date`: Attempt ${i}: remount rootfs failed! Trying
again..." #| tee -a $LOG
echo "`date`: Attempt ${i}: remount rootfs failed! Trying
again..." >> $LOG
# sleep 1
{ cat /proc/mounts ; echo ; ps aux ; echo ; /usr/bin/lsof
; echo ; } >> $LOG
/bin/fuser -v -m -u / 1>/dev/null 2>> $LOG
sleep 1
else
break
fi
done
=========================
Today's morning I've got a 21 message "/ is busy" at shutdown.
Early, I thought that the cause is that some processes are accessing the disk
during shutdown (writing). Some processes which are not terminated on time, so
" / is busy " message appears.
Now I'm looking into logs and... Well, looks like it isn't the real cause.
I don't see any files opened for writing (except pipe, @/com/ubuntu/upstart,
/dev/null and /dev/console).
So, more and more I think, that this bug is in 'init/upstart'... or in kernel!
It's not so easy to reproduce it. I've tried a lot of times to reboot machine
under heavy cpu and I/O load and bug doesn't apper (a lot of times in about
10-15 minutes).
But bug appears more frequently when uptime is high enough (at least 1/2 of a
day).
Steps to reproduce: push power button from running X session.
One more interesting thing: my root partition is on usb hard drive.
If I'll have some more free time near future, I'll try to test it with a
new kernel ( > 3.5).

Title:
Ext4 corruption associated with shutdown of Ubuntu 12.10
Status in Upstart:
Confirmed
Status in “linux” package in Ubuntu:
Incomplete
Status in “network-manager” package in Ubuntu:
Triaged
Status in “upstart” package in Ubuntu:
Confirmed
Bug description:
1. Format and label a target Ext4 partion using Ubuntu 12.04
2. Install 64bit 12.10 OS using that target without reformatting it
3. Shut down
4. Boot an alternate copy of Ubuntu
5. Restart selecting the newly installed OS
6. Login then shutdown
6. Boot an alternate copy of Ubuntu
7.Fsck the newly installed OS allowing corrections to be made
Each time the the newly installed OS is executed and then shutdown,
even if execution only consists of logging on, a subsequent fsck will
FAIL.
I used Acronis True Image Home 2013 to create an image of the newly
installed 64-bit Ubuntu 12.10, so I can recreate the symptoms of Ext4
filesystem corruption 100% of the time by restoring from the image,
booting, logging on and shutting down.
