http://bugzilla.opensuse.org/show_bug.cgi?id=1201114 http://bugzilla.opensuse.org/show_bug.cgi?id=1201114#c3 --- Comment #3 from Stanislav Brabec <sbrabec@suse.com> --- This is very strange: Jul 07 13:52:20 Mobile-PC kernel: BTRFS warning: duplicate device /dev/sdc2 devid 1 generation 6733 scanned by mount (4717) It looks that even if everything was correctly unmounted, something in the kernel still holds a record for /dev/sdb2, which prevents it from releasing. Just a dumb idea: What happens if you do rmdir /mnt/chroot after unplug, but before replug. It seems, that something becomes bound to this directory, but it is not a mounted volume. Does the bug happens then? Does the device get name sdb2 or sdc2 then? In any case, it looks like a kernel problem that has nothing to do with mount/libmount. -- You are receiving this mail because: You are on the CC list for the bug.
