It broke only becaus= e of a=20 btrfs bug hitting two of the four nodes (after ca. one day of heavy loa= d) and=20 recovered without problems when the nodes were back. Then I recreated w= ith=20 ext4 as osd storage area and have not managed to break it within four d= ays,=20 two of these under heavy load. This means that this bug is probably fixed. It might be related to the=20 automatic reconnect of mds, which avoids meta data inconsistencies. :) Amon Ott --=20 Dr. Amon Ott m-privacy GmbH Tel: +49 30 24342334 Am K=F6llnischen Park 1 Fax: +49 30 24342336 10179 Berlin http://www.m-privacy.de Amtsgericht Charlottenburg, HRB 84946 Gesch=E4ftsf=FChrer: Dipl.-Kfm.
