Hi! the last days, I updated my jessie evaluation cluster to jewel and now osds are not started automatically after reboot because they are not mounted. This is the output of ceph-disk list after boot: /dev/sdh : /dev/sdh1 ceph data, prepared, cluster ceph, osd.47, journal /dev/sde1 /dev/sdi : /dev/sdi1 ceph data, prepared, cluster ceph, osd.48, journal /dev/sde2 /dev/sdj : /dev/sdj1 ceph data, prepared, cluster ceph, osd.49, journal /dev/sde3 and so on. systemd tried to start the units: # systemctl | grep osd ● ceph-osd@47.service loaded failed failed Ceph object storage daemon ● ceph-osd@48.service loaded failed failed Ceph object storage daemon ● ceph-osd@49.service loaded failed failed Ceph object storage daemon # systemctl status ceph-osd@47.service ● ceph-osd@47.service - Ceph object storage daemon Loaded: loaded (/lib/systemd/system/ceph-osd@.service; enabled) Active: failed (Result: start-limit) since Wed 2016-04-27 08:50:07 CEST; 21min ago Process: 3139 ExecStart=/usr/bin/ceph-osd -f --cluster ${CLUSTER} --id %i --setuser ceph --setgroup ceph (code=exited, status=1/FAILURE) Process: 2682 ExecStartPre=/usr/lib/ceph/ceph-osd-prestart.sh --cluster ${CLUSTER} --id %i --setuser ceph --setgroup ceph (code=exited, status=0/SUCCESS) Main PID: 3139 (code=exited, status=1/FAILURE) Apr 27 08:50:06 ceph-cap1-02 systemd[1]: Unit ceph-osd@47.service entered failed state. Apr 27 08:50:07 ceph-cap1-02 systemd[1]: ceph-osd@47.service start request repeated too quickly, refusing to start. Apr 27 08:50:07 ceph-cap1-02 systemd[1]: Failed to start Ceph object storage daemon. Apr 27 08:50:07 ceph-cap1-02 systemd[1]: Unit ceph-osd@47.service entered failed state. Which is no suprise as the osd is not mounted: # ls -l /var/lib/ceph/osd/ceph-47 total 0 The weird thing is running the following starts the osd: # echo add > /sys/class/block/sdr1/uevents so the udev rules to mount the osds seem to work. Any ideas on how to debug this?
