[Bug 1667512] Re: update-initramfs hangs on upgrade, dpkg unusable, unbootable system
** Description changed: - At least four users, including myself, are having an issue with update- - initramfs hanging while updating ubuntu 16.04. The bug has been - documented while attempting an update to multiple kernel versions ( - 4.4.0-24, 4.4.0-62, 4.4.0-63). The bug causes any apt-get update or - install to fail, and may also lead to an unbootable system. + [Impact] + If there is lots of activity on a different filesystem, high io/cache pressure, or a stale mount updating initramfs might hang because the update-initramfs script calls sync. This leaves the system unresponsive and will require the user to forcefully kill dpkg. + + [Test Case] + One easy way to simulate this is by copying a huge file over nfs. Note: do not use localhost, it is too fast for this purpose, a network bridge over qemu is good enough. + + 1. Setup a nfs server and export a directory with write permissions for + the client + + 2. Copy a big file over NFS (assumes it is mounted at /mnt in the client) + $ dd if=/dev/zero of=/mnt/big_zeros bs=512 count=1M status=progress + Note: adjust the "count" accordingly to how fast/slow your system is. + + 3. Call sync and verify that it only finished after "dd" is done. + + 4. Repeat step #2 and now call "sync -f /boot/". + Verify that it finished immediatly. + + [Regression Potential] + Although syncfs(2) man page [2] states that it works just the same as sync - except being limited to a filesystem -, any actual differences in the implementation can affect how the initrd image file is synced to the disk, leading to unexpected behavior. + + [Other] + If syncfs is unsupported then the 'sync' binary will ensure that a normal system-wide sync is called [1]. The proposed patch won't help in scenarios where the initrd file is located in a busy filesystem (eg. no separated /boot partition). + + The 'sync' and 'syncfs' specifications are pretty much similar and + syncfs is expected to work the same as a normal sync regarding data + integrity. Also altought the patch introduces the initrd file as an + extra argument which would cause 'sync -f' to fail if the file does not + exist, the update-initramfs script would fail earlier than that because + that file is created by the 'mv' call a few lines above. Thus no + regressions are expected. + + [References] + [1] http://git.savannah.gnu.org/cgit/coreutils.git/commit/src/sync.c?id=8b2bf5295f353016d4f5e6a2317d55b6a8e7fd00 + [2] http://manpages.ubuntu.com/manpages/xenial/man2/syncfs.2.html + + [Original bug report] + At least four users, including myself, are having an issue with update-initramfs hanging while updating ubuntu 16.04.

atom's suggestion to stop all disk operations was the key to fixing this. I had a ddrescue operation going on in the background that I stopped after reading this thread, and BAM it started moving up from 37% and eventually finished. Basically, this issue affected me as well on Ubuntu 14.04 x64, when trying to update my nvidia drivers from graphics-drivers ppa. I did 'sudo apt install nvidia-384' and it was stuck at 37% saying 'update- initramfs: Generating /boot/initrd.img-3.13.0-144-generic' for 20+ minutes. At that point I went to /boot/ and saw that a 'initrd.img-3.13.0-144-generic.new' was sitting around with a 0 file size since 20 minutes ago. Something was stuck but I didn't know until reading this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667512 Title: update-initramfs hangs on upgrade, dpkg unusable, unbootable system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1667512/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also take sync out of commission in order to allow for a clean shutdown
(important: re-enable after the reboot!). Also give the system enough time to
sync all its buffers on its own before restarting.
cd /bin
mv sync sync.real
cp ls sync
This helped me before and now I have the deadlocked sync issue again.

[Bug 1667512] Re: update-initramfs hangs on upgrade, dpkg unusable, unbootable system
Thanks atom! Indeed, we also had a stale nfs share and an automatic apt-get security update that left our ubuntu 16.04. server in an unclean state since it would silently hang on update-initramfs. Because the mounted nfs share remained unresponsive, update-initramfs was hanging for several days. Killing it and rerunning sudo dpkg --configure -a would result in a deadlock and no other apt-get was possible since dpkg couldn't finish its last operation. Calling update-initramfs manually would also hang and could only be stopped with kill -9 (ctrl+c did not work). Commenting out the sync command in the generate_initramfs function of /usr/sbin/update-initramfs worked to restore the system to a rebootable state! However a soft shut down didn't work either (shutdown -r now) presumably because it tried to sync the stale nfs mount again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667512 Title: update-initramfs hangs on upgrade, dpkg unusable, unbootable system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1667512/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1667512] Re: update-initramfs hangs on upgrade, dpkg unusable, unbootable system
Me too.
Turns out the problem for me is updating *while* copying a hard-drive
(in another terminal).
The "update-initramfs" script calls "sync" in the "generate_initramfs"
function. For me, copying hard-drives at the same time caused "sync" to
hang: Then the whole thing hangs.
I CTRL-Z'd (TSTP) my rsync process (doing the copying), and a few
seconds later update-initramfs un-hung. Finished without a problem.
Proposed workarounds:
1- stop/pause large disk i/o operations while updating, or
2- edit "/usr/sbin/update-initramfs": comment out the "sync" command in the
"generate_initramfs" function
This is why Ubuntu (and other Linux distros) needs a user-space "fsync"
command; so instead of trying to sync busy drives that could be busy for
days, it can just "fsync ${file}" and get on with the day.
Not sure if this will fix anyone else's problems, but it's all unicorns
and rainbows over here, now.

Have the same problem since yesterday. I'm having 4.4.0-47 4.4.0-59 4.4.0-62 4.4.0-64 installed. I was trying to upgrade my system yesterday and 4.4.0-66 was about to be installed, but it hangs on update-initramfs or to be more precise it's hanging on "Building cpio" when running update-initramfs -u -v Problem is related probably to last 2 upgrades which I did.
