HI,

My storage health cluster is warning state , one of the osd is in down state and even if I try to start the osd it fail to start

 

sadhu@ubuntu3:~$ ceph osd stat

e22: 2 osds: 1 up, 1 in

sadhu@ubuntu3:~$ ls /var/lib/ceph/osd/

ceph-0  ceph-1

sadhu@ubuntu3:~$ ceph osd tree

 

# id    weight  type name       up/down reweight

-1      0.14    root default

-2      0.14            host ubuntu3

0       0.06999                 osd.0   down    0

1       0.06999                 osd.1   up      1

 

sadhu@ubuntu3:~$ sudo /etc/init.d/ceph -a start 0

/etc/init.d/ceph: 0. not found (/etc/ceph/ceph.conf defines , /var/lib/ceph defines )

sadhu@ubuntu3:~$ sudo /etc/init.d/ceph -a start osd.0

/etc/init.d/ceph: osd.0 not found (/etc/ceph/ceph.conf defines , /var/lib/ceph defines )

 

 

Ceph health status in warning mode.
