The newly found problem is not btrfs speficic: echo "/ext4.img /ext4_mnt1 auto loop 0 0" >>/etc/fstab mount -a echo "/ext4.img /ext4_mnt2 auto loop 0 0" >>/etc/fstab mount -a mount umount /ext4_mnt1 /ext4_mnt2 sed -i /ext4.img/d /etc/fstab Result: Nothing was mounted into /ext4_mnt2 (This is the problem with loop files in fstab, which I mentioned in my past mails, but was not able to reproduce.) It also means, that I still don't have a reproducer that will demonstrate mount confused by an incorrect subvol provided by kernel. -- Best Regards / S pozdravem, Stanislav Brabec software developer --------------------------------------------------------------------- SUSE LINUX, s. r. o. e-mail: sbrabec@suse.com Lihovarská 1060/12 tel: +49 911 7405384547 190 00 Praha 9 fax: +420 284 084 001 Czech Republic http://www.suse.cz/ PGP: 830B 40D5 9E05 35D8 5E27 6FA3 717C 209F A04F CD76
