I have an OSD that is down and when I try and start it I get 'bad checksum on
pg_log_entry_t' logged to the console.
Here is a complete dump of running this OSD from the commandline
root@cephosd4 ~]# /usr/bin/ceph-osd -i 35 --pid-file /var/run/ceph/osd.35.pid
-c /etc/ceph/ceph.conf --cluster ceph -f
starting osd.35 at :/0 osd_data /var/lib/ceph/osd/ceph-35
/var/lib/ceph/osd/ceph-35/journal
terminate called after throwing an instance of 'ceph::buffer::malformed_input'
what(): buffer::malformed_input: bad checksum on pg_log_entry_t
