I did a bit of hacking on init.d/umountroot, adding lsof and ps -ef after the remount fails. I could see that dhclient was still running, so I added before the remount: pkill -9 dhclient
After this change, dhclient was gone, but the remount still failed. In lsof output I can see: init 1 root 15w REG 8,24 1134 438383 /var/log/upstart/mountall.log It seems like there is a problem in the upstart init where it is not closing files, besides the problem with dhclient. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1073433 Title: Ext4 corruption associated with shutdown of Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/1073433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
