Update: I recreated the Ceph FS with release 0.40. It broke only because of a
btrfs bug hitting two of the four nodes (after ca. one day of heavy load) and
recovered without problems when the nodes were back. Then I recreated with
ext4 as osd storage area and have not managed to break it within four days,
two of these under heavy load.
This means that this bug is probably fixed. It might be related to the
automatic reconnect of mds, which avoids meta data inconsistencies. :)
