I can reproduce this on Wily with
# apt-cache policy ceph
ceph:
Installed: 0.94.5-0ubuntu0.15.10.1
Candidate: 0.94.5-0ubuntu0.15.10.1

when I configure two OSDs both with their journal partition on a third
disk. Running os-prober makes the second OSD fail with
0> 2016-02-16 15:15:17.604773 7fe2c7ec8700 -1 os/FileJournal.cc: In

NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to
interpret this.
which seems to indicate that os-prober is doing unsafe things to the
journal partitions.
