Also, anyone looking to debug shutdown issues should do three things: Set up a serial console on the affected machine by adding (there is a lot of documentation out there on how to do this) Add --verbose to the kernel parameters (the APPEND line if you are PXE booting) Change. Change VERBOSE to 'yes' in /lib/init/vars.sh That is how I was able to work out what was going on. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to cloud-initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1165886 Title: overlayroot prevents shutdown / reboot under nfsroot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1165886/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1165886] Re: overlayroot prevents shutdown / reboot under nfsroot
Turns out that the /etc/network/interfaces stuff I mentioned before was a red herring, here is the actual problem. Without overlayroot the (nfs) root filesystem is mounted at /, and on reboot/shutdown /etc/init.d/umountnfs.sh will skip that mount point when unmounting the network file systems (because of lines 49 50 of /etc/init.d/umountnfs.sh). With overlayroot enabled, the root filesystem is mounted at /, but the nfs mount that is under the overlay is mounted at /media/root-ro, which is NOT skipped during reboot/shutdown. The fix I have in place is to change line 49 of /etc/init.d/umountnfs.sh from: /|/proc|/dev|/dev/pts|/dev/shm|/proc/*|/sys|/run|/run/*) to: /|/proc|/dev|/dev/pts|/dev/shm|/proc/*|/sys|/run|/run/*|/media/root- ro) And I am able to reboot/shutdown properly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165886 Title: overlayroot prevents shutdown / reboot under nfsroot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-initramfs-tools/+bug/1165886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
