Ceph: osd does not being up after reboot

sudo chown -R ceph:ceph /var/lib/ceph
sudo chmod -R 777 /var/lib/ceph

/etc/rc.local

sudo chown ceph:ceph /dev/journal1
sudo chown ceph:ceph /dev/journal2
sudo chown ceph:ceph /dev/journal3...

chmod +x /etc/rc.local
sudo reboot

Run the commandline bottom, after activated all osd on the osd-nodes.

grep osd/ceph- /proc/mounts

The output of the commandline below is like;

/dev/sdc1 /var/lib/ceph/osd/ceph-0 xfs rw,noatime,attr2,inode64,noquota 0 0
/dev/sdd1 /var/lib/ceph/osd/ceph-1 xfs rw,noatime,attr2,inode64,noquota 0 0
/dev/sde1 /var/lib/ceph/osd/ceph-2 xfs rw,noatime,attr2,inode64,noquota 0 0
...

Add this output to /etc/fstab file. If you see all osds are up now, then reboot osd nodes. Osds will be all down and up again.


You can also try to add below codes to /etc/rc.local and reboot.

sudo start ceph-osd id=0 (id of the osd)
sudo start ceph-osd id=1
sudo start ceph-osd id=2
sudo start ceph-osd id=...
