hi
encouraged by the roadmap mail I started my tests with
CEPH_NUM_MDS=3 (mon,osd: just one instance). OS is Debian Squeeze with
kernel 2.56.35.4
bonnie++ hangs after this output:
Using uid:0, gid:0.
Writing a byte at a time...done
Writing intelligently...done

<end of output>
after killing the bonnie++ processes, the other tests go on. mds1
crashed shortly after killing bonnie++.
output from mds(0|1|2) logs:
