Your aufs is the root filesystem, isn't it? Generally speaking, the root filesystem cannot be unmounted. It is remounted as readonly at shutdown/reboot time. How about this procedure instead of unmounting aufs? mount -no remount,ro /aufs for i in $writable_branches do mount -no remount,ro $i done exit If your xino files were on a hard drive, it is better to specify 'noxino' too. > So, if the union can't be unmounted, I thought to remove the writable > branch from it, using 'mount -o remount,del:/mnt/changes aufs /union'. > Unfortunately this doesn't work either and there is no info in dmesg why > that failed. That is strange. When you executed remount, was your syslogd up and running? The major reasons to reject deleting a branch are, - there is only one branch left in aufs. - a file or something is in use on the branch. - a directory is in use (which lsof may not show), and the directory doesn't exist on any other branch.

Please send me the output of this script.
Set $path correctly before you execute it.

umount busy aufs
Hello, In linux-live scripts, I'm using aufs to join read-only branches with one writable branch at the top, so my setup is like the following: /union := /mnt/changes (a rw branch) /mnt/images/br1 (a ro branch) /mnt/images/br2 (a ro branch) /mnt/images/br3 (a ro branch) /mnt/images/br4 (a ro branch) :: (xino path is somewhere else, in /mnt/xino/, not in the rw branch) During reboot, some processes which can't be killed (eg. init) are running from the union, (/union/sbin/init for example). My goal is to properly save all filesystem modifications in the writable branch. So first I tried to cleanly unmount the union, but it's busy and can't be unmounted. So, if the union can't be unmounted, I thought to remove the writable branch from it, using 'mount -o remount,del:/mnt/changes aufs /union'. Unfortunately this doesn't work either and there is no info in dmesg why that failed. I think aufs thinks the branch is busy. But I believe there are no more open files from the writable branch, so it shouldn't fail. Using lsof shows that only /union/dev/initctl is open, but /union/dev is overmounted by tmpfs, so the file is not in fact in the union, but somewhere else. Is there a possible way to find out what's wrong? How to debug why aufs doesn't want to delete the branch? Some kind of 'lsof' for aufs, which would show me what files are open on the given branch, or why the branch is busy. Thank you very much for any help.
