[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
Hi Based on some of your comments I tried to find what was the issue with the umount The below command helped me to get the information who is holding the lock so based on Serge Hallyn (serge-hallyn) request the error shows as follows, (lsof didn't help me much here so I used fuser) - # fuser -f -v /tmp/tmp4WlrLItmpfs USERPID ACCESS COMMAND /tmp/tmp4WlrLItmpfs: root kernel mount /tmp/tmp4WlrLItmpfs - Based on the above information where I can not kill the PID becuase kernel is holding the lock. So what would be my option here?

[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
I just wanted to bump this issue as I've been experiencing it without
fail for the last two days and the posted workaround has not resolved
the issue. Currently running 11.10 x64. My command line has been:
sudo vmbuilder kvm ubuntu -v --debug --suite=lucid --flavour=virtual
--rootsize=4096 --swapsize=1024 --mem=388 --arch=i386 --user=system
--pass=changemenow --components=main,universe,restricted --addpkg=acpid
--addpkg=openssh-server -o --libvirt qemu:///system
The error noted before crashing out has consistently been:
2012-03-16 13:59:53,564 ERROR : Process (['umount', '/tmp/tmptaOMHF/dev'])
returned 1. stdout: , stderr: umount: /tmp/tmptaOMHF/dev: device is busy.

Prior to the crash, mount indicates indeed, the file (/tmp/tmptaOMHF/dev
in this case) is still mounted, the file is also notable in /etc/mtab
post-crash.
I've noted that in the lsof results inserted just prior to the mount call,
there appear to be three cron processes still accessing /dev/null within the
mounted environment (i.e. /tmp/tmptaOMHF/dev/null). I'm attaching a log which
contains the results output from the inserted:
run_cmd('lsof', '%s/dev' % self.context.chroot_dir) line onward until
vmbuilder exits, crashing.
I have successfully built several VMs on this particular machine in the
past, using the exact same command, so I was a bit surprised to be
running into this issue now, any ideas?

Re: [Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
I see this every time on one KVM host machine and never on my other KVM host machine. Good one is: Fully patched 11.10 Server (no desktop) acting as KVM host using vmbuilder to create guest instances of 11.10 server. Bad one is: Fully patched 11.10 Workstation with Virtualization packages added executing the exact same command line. I created a shell script to contain my vmbuilder command line and copied it to both host machines to be sure that I was performing identical activities on each. I did dig through the Python traceback enough to locate the line throwing the exception. Adding a simple sleep for 5 seconds makes it work every time. I tried to add the suggested debug statements regarding the determination of who is holding the mount point busy. But, for the life of me, I could not figure out where the log file went to -- where is the output of the debug being written? I'm willing to investigate more if it's of service to anyone.

[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
I added this corresponding line:
def unmount_dev(self):
self.context.cancel_cleanup(self.unmount_dev)
run_cmd('chroot', '%s' % self.context.chroot_dir,
'/etc/init.d/cron','stop') // -- HERE
run_cmd('umount', '%s/dev' % self.context.chroot_dir)
That seems to be a temporary workaround for the problem I was seeing
(same as @rchilliard -- lsof showed a cron open file to /dev/null).
I also had this working up until several days ago without anything else
changing and then it suddenly broke.

I will attach the debug log vmbuilder with --addpkg ubuntu-desktop and debug
lines:
run_cmd('lsof', '%s/proc' % self.context.chroot_dir)
run_cmd('lsof', '%s/dev/pts' % self.context.chroot_dir)

[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
Ouch. I replaced the code with the new lines and ran vmbuilder twice.
Unfortunately everything worked fine this way and I couldn't reproduce
the problem again (obviosuly I removed the run_cmd('sleep', '10') fix
too).
I experienced something similar with another server, at first vmbuilder
crashed but after making some other changes (like apt-get installing
something else, totally unrelated) vmbuilder was able to complete its
job and never saw the problem again in that server.
I'm wondering if this could be related to getting stuck in some hard
disk sector but that doesn't make much sense. The other server I'm
referring to is a 4-years-old Core 2 Duo laptop and my current server is
a brand new Core i5 desktop, so hardware seems totally unrelated.
I'll let you know if I can reproduce the problem again, sorry I can't
help more for now.

Re: [Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
Hm, thanks.

[Bug 879710] Re: ubuntu-vm-builder crashes when trying to umount tmp directory.
A simple workaround is simply add some sleep as follows.
def unmount_dev(self):
self.context.cancel_cleanup(self.unmount_dev)
run_cmd('sleep', '10'); // --- add this line.
run_cmd('umount', '%s/dev' % self.context.chroot_dir)
Above
