[Bug 1019347] Re: A message: mount: / is busy appears every time shutting down or rebooting.
Hi- I was at a friends and his dell computer wouldn't shut down right. It is Ubuntu 12.04. It hung on shutdown. Available to all users did nothing to solve this for my friend. I tried maybe the uncovential method of renaming /etc/init/plymouth.conf to ... plymouth.conf.disabled. After that, I had to go to rescue system to put it back by renaming it back to original. I had to mount root in rescue system as read/write to rename again. Plymouth on crunchbang didn't work for me on usb live persistent, but that is another story. My thought was, as per other peoples reports, to disable plymoth to eliminate that plymouth was causing this problem. My friend has a pc that he can't shut down, unless he holds down the power button. I don't know what to tell him at this point. Using the command line to shut down doesn't work either. It seems weird that I run unbuntu 12.04 and my pc works fine and his doesn't. I think it is a hardware related issue with a driver or firmware or something different. I can brag and say that I have a ZaReason, but my friend is not so lucky. I am going to tell him to either buy dell for linux, system76 or zareason if he wants a new one. I can't fix it :-( I gave up after having to go to rescue mode and undo disabiling plymouth. thanks, mtdew3q -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019347 Title: A message: mount: / is busy appears every time shutting down or rebooting.

[Bug 1019347] Re: A message: mount: / is busy appears every time shutting down or rebooting.
It's been a couple of months but I finally got around to revisit this bug. I had this happen reliably on 2 laptops, both updated from previous versions of Ubuntu. On one of these plymouthd really seemed to be the culprit (see my own comment #22 ). I found out that the memory mapped region was actually opened in plymouth's X11 frame renderer (through libdconfsettings.so which seems to be part of gio). Uninstalling the X11 renderer (apt-get remove plymouth-x11) helped on this laptop. But this package wasn't even installed on the other laptop. Here, it was an instance of git-daemon (a runit service) which was still running causing svlogd to still keep a log file open. After uninstalling (apt- get remove git-daemon-run) the busy mount at first seemed to have disappeared on this machine, too. But yesterday I had another busy mount caused by modem-manager still running which caused init to keep a log file handle open on /var/log/upstart/modemmanager.log. So, in conclusion this is probably more of a meta-issue concerning a wider range of packages which would explain why the mentioned workarounds do not fix this issue reliably for everyone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019347 Title: A message: mount: / is busy appears every time shutting down or rebooting.

This gives me the feeling that this is probably a widespread problem among ubuntu users. Nevertheless, most users are likely not aware of this since they only use the (unity) GUI which does nowhere report this problem! I don't know what the root cause of this problem is, but the only currently known symptom (cause) is that plymouthd does not exit at shutdown.Therefore I'm setting back the status to confirmed. ** Changed in: plymouth (Ubuntu) Status: Expired = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019347 Title: A message: mount: / is busy appears every time shutting down or rebooting.

I guess I'll just have to try to find this the old-fashioned way. I'll do a minimal netinstall in VirtualBox and build up the operating system one by one, keep rebooting in the meanwhile and wait until the problem starts to occur.

I've found it. Purging dnsmasq-base solves the problem. Sadly, this is a dependency of network-manager, so it's not really an option to do so. Can others confirm that this works for them?

Eduard, you are correct, I added some debug output to the kernel itself (in fs/file_table.c) to log the inode number that causes sys_mount to return EBUSY.

This has been present in all kinds of iterations of 12.10 for quite a while now. Unless you remove quiet splash from /etc/default/grub the message obviously won't show up, but it will cause Plymouth to hang on the shutdown splash screen for quite a while. Not only does this cause a risk of data loss due to the unclean unmount, it also makes the shutdown process last unnecessarily long. Compared to 12.04, 12.10 shuts down very slowly.

This problem is not universally reproducible. I don't see any of these problems in 12.10 - I certainly don't think this is a plymouth bug, since plymouth runs on everyone's systems.

Running 'sudo service networking stop' prior to shutting down decreases the time needed by nearly 100%. Still, the message about / being busy persists.

Never mind; fsck does come by: [1.562038] EXT4-fs (sda2): INFO: recovery required on readonly filesystem [1.562044] EXT4-fs (sda2): write access will be enabled during recovery [1.572388] EXT4-fs (sda2): recovery complete [1.572862] EXT4-fs (sda2): mounted filesystem with ordered data mode. Opts: (null) Even though the message is always like this - so I doubt any serious consequences will follow - this isn't right. I'll try to find out why this is happening, but it's a really confusing situation. The strange thing is; it happens both in VirtualBox running on my Debian PC and on my laptop running Xubuntu 12.10 natively. Also, I've seen it happen with a completely unmodified Ubuntu 12.10 install (VirtualBox) and a netinstall image with manually configured Xubuntu 12.10 packages (laptop). I do remember though, that it doesn't happen directly after installing a netinstall image, so I doubt we'd have to look in the packages that are part of ubuntu-minimal and ubuntu- standard, although I'd have to double-check that later.

[Bug 1019347] Re: A message: mount: / is busy appears every time shutting down or rebooting.
This bug report is highly confusing, so let me state this more clearly: the plymouthd process is still running at the point where /etc/init.d/umountroot is run in the shutdown process, and it is holding some rw file descriptor stopping / from being remounted ro, thus causing an unclean shutdown (and a longer boot time because the journal needs to be replayed). I don't know what plymouthd is supposed to be, but I'm pretty sure it should be dead at that point in the shutdown process. For some reason, it is not responding to TERM signals: this should maybe be considered a bug in plymouthd (notwithstanding the thought that plymouthd is a bug in and of itself). I didn't figure out what the offending rw file descriptor was. I also don't know why only certain users are affected (this is probably related to the details in partitioning). The obvious, but ugly, workaround is to edit /etc/init.d/umountroot to add a line such as /usr/bin/killall -9 plymouthd at the top of the do_stop() function (probably a good idea to add a couple of sync's around that, too). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019347 Title: A message: mount: / is busy appears every time shutting down or rebooting.

I found that instead of 'killall' it is also possible to invoke /bin/plymouth quit. So it seems that plymouth is still honoring quit requests. Why it doesn't honor the first quit request (or if there is any quit request) is beyond my knowledge. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1019347 Title: A message: mount: / is busy appears every time shutting down or rebooting.

[Bug 1019347] Re: A message: mount: / is busy appears every time shutting down or rebooting.
Hi, taking advice from other threads, I added an ps and lsof commands to the umountroot script just before the root remount command. The result is attached. As you can see the only non-kernel/init programs running are rc, S60umountroot and plymouthd. Thou I couldn't find in the lsof which is the open file that makes / busy, I agree that plymouthd shouldn't be running at this stage. Hope this helps with debugging. My system is not clean install, upgraded several times, maybe this is the source of the problem.

Hi, I was browsing on the net and found this link:
http://ubuntuforums.org/showthread.php?t=2008576 . I think my problem is
related to the freezing plymouthd that does not get killed on
rebooting or shutting down.
As instructed in the link, I put a bash script which content was:
#! /bin/sh
ps -Af process.log
in /etc/rc6.d before the S60umountroot script file. I opened the
process.log file in root directory and find this:
root 2842 2 0 18:27 ?00:00:00 [kworker/0:3]
root 2854 1 1 18:27 ?00:00:00 /sbin/plymouthd --mode=shutdown
root 2890 2 0 18:27 ?00:00:00 [kworker/u:0]
I did the first solution on the link. What I did was:
1. I renamed the file of S60umountroot that is in /etc/rc6.d and /etc/rc0.d
to S61umountroot.
2. Created a file named S60perso-script and set it to be executable in
/etc/rc6.d and /etc/rc0.d .
The content of the S60perso-script was as follows:
#! /bin/sh

That's it! And, the mount:/ busy message does not appear again on
shutting down or rebooting. And I think the problem was not in upstart.
