[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

It looks like something on your system was using a file in /mnt, thus it could not be unmounted. You can find out what program is doing so by using lsof. -- 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

I'm not able to reproduce it here.

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

I'm a little confused. You said that you mounted the other volume in /mnt/test2, but that umount /mnt/boot works.
