Unable to start Ceph

[maomaocake]

Hi, I just did a hard disk swap and all the osds on a node is not able to start with the service

`systemctl start ceph-osd@0`
the output of systemctl status ceph-osd@0 is

ceph-osd@0.service - Ceph object storage daemon osd.0

However the command to start the OSD:
/usr/bin/ceph-osd -f --cluster ceph --id 0 --setuser ceph --setgroup ceph &
works fine

what am I missing

Hello,

You have too many restart attempts for the systemd service associated to such OSD, please run

systemctl reset-failed

If the OSD does not start working after that, you could try to restart the OSD service again. Should that fail, restart all Ceph services one by one by, e.g.

systemctl restart ceph-osd@0.service

for restarting OSD 0 or

systemctl restart ceph-mon@$(hostname).service

to restart the MON service. Please check Ceph's health before the next command via `ceph -s`. You can get a full list of Ceph services running on the current host via:

systemctl list-units --type=service |grep ceph
