[Bug 1358310] Re: using umount with bash wildcard ends in device is busy for mount of parent directory
no, like described in my initial post lsof does not show anything in this case. also there is no reason to assume that any process (other than umount) is opening a file in /mnt if you use the commands i've posted. it is reproducible with the kernel version i've posted and it only happens if umount is called on /mnt/issue (e.g. by umount /mnt/*). however, it looks like newer kernel versions do not have this issue. so it seems like someone fixed 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/1358310 Title: using umount with bash wildcard ends in device is busy for mount of parent directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1358310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry i wrote /mnt/boot by mistake because it was that in my first test. It should be umount /mnt/test2.

[Bug 1358310] [NEW] using umount with bash wildcard ends in device is busy for mount of parent directory
Public bug reported: hi, i've run into a problem on ubuntu 14.04 while mounting an ganeti instance for doing some chroot stuff. but the problem itself not related to ganeti or any other virtualization. its just a problem while mounting/unmounting some devices. so heres an example how to reproduce the problem: lvcreate -L 1G -n test system lvcreate -L 1G -n test2 system mkfs.ext4 /dev/system/test mkfs.ext4 /dev/system/test2 mount /dev/system/test /mnt/ mkdir /mnt/test2 mount /dev/system/test2 /mnt/test2/ ln -sf /etc/issue /mnt/ umount /mnt/* umount /mnt/ lvremove -f /dev/system/test2 lvremove -f /dev/system/test if i run this commands /mnt/ is still mounted and it is only possible to umount it using -l switch. but after this it is still not possible to remove the logical volume because it says Logical volume system/test contains a filesystem in use. if i run the same commands but without the ln -sf /etc/issue /mnt/ everything is okay. also if i replace umount /mnt/* with umount /mnt/boot everything works. so it seems like umount ist opening /etc/issue for some reason if a bash wildcard is used and not releasing it. checking with lsof or fuser does not show any open files under /mnt/ nor for /etc/issue. the problem does not exist with ubuntu 12.04. a solution for this problem would be great because if you often do some chroot stuff it is easier to use umount /mnt/* to umount all bind mounts like /proc/ or /sys/ than running a umount command for each mount. also i havent found a way, other than reboot, to remove an open logical volume if it was hit by this problem. lsb_release -rd Description:Ubuntu 14.04.1 LTS Release:14.04 regards the2nd ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358310 Title: using umount with bash wildcard ends in device is busy for mount of parent directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1358310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
