Hello, I have an aufs filesystem mounted with several branches and I need to delete one branch from aufs to umount it completely. I've done the following:
mount aufs mntaufs -t aufs -o br:mnt1=rw,mnt2=ro mount -o remount,del:mnt1 mntaufs umount mnt1 result: I can't umount mnt1, because device is busy. lsof gives nothing. In some cases even after unmounting the aufs filesystem I can't umount mnt1. If I mount all branches ro into aufs from the beginning, there are no problems. But the following doesn't work either: mount aufs mntaufs -t aufs -o br:mnt1=rw,mnt2=ro mount -o remount,mod:mnt1=ro mntaufs (or rr) mount -o remount,del:mnt1 mntaufs umount mnt1 dmesg shows: aufs au_opts_verify:1332:mount[5232]: first branch should be rw, but I don't get any error while doing the remount,del operation. I tried to prepend a writable branch in front of mnt1 before deleting it, but no luck either. Any ideas or suggestions to help would be great! I'm running a linux 2.6.32 kernel with aufs2. K.
