Hello, working with ceph on my test configuration (3 nodes Ubuntu 10.04.1 LTS, Linux 2.6.32-24-generic-pae #41-Ubuntu SMP) After starting svn co https://root.cern.ch/svn/root/trunk root on the /ceph directory, the command become stuck, and also: root 5303 0.0 0.0 0 0 ? D Aug26 0:00 [kjournald] root 30181 0.0 0.0 6972 2056 pts/1 D+ 13:46 0:00 /usr//bin/cosd -i 2 -c /etc/ceph/ceph.conf any mount, unmount are going also to the state D. This is a permanennt behaviour of the ceph if the command is started. dmesg shows: ------------- [99048.567704] ------------[ cut here ]------------ [99048.568767] kernel BUG at /build/buildd/linux-2.6.32/fs/ext3/balloc.c:1384!
