<p>Hi All,<br />We monitored two of our osd as down using the ceph osd tree command. We tried starting it using the following commands but ceph osd tree command still reports it as down. Please see below for the commands used.</p>
<pre><span style="font-family: andale mono,times;">command:sudo start ceph-osd id=osd.0</span><br />output: ceph-osd (ceph/osd.0) stop/pre-start, process 3831<br /><br />ceph osd tree output:<br /># id weight type name up/down reweight<br />-1 5.13 root default<br />-2 1.71 host ceph-node1<br />0 0.8 osd.0 down 0 <br />2 0.91 osd.2 down 0 <br />-3 1.71 host ceph-node2<br /><br />command: sudo start ceph-osd id=0<br />output: ceph-osd (ceph/0) start/running, process 3887<br /><br /></pre>
<pre>ceph osd tree output:<br /># id weight type name up/down reweight<br />-1 5.13 root default<br />-2 1.71 host ceph-node1<br />0 0.8 osd.0 down 0 <br />2 0.91 osd.2 down 0 <br />-3 1.71 host ceph-node2<br /><br />command: sudo start ceph-osd id=0<br />output: ceph-osd (ceph/0) start/running, process 4348<br /><br /></pre>
<pre>ceph osd tree output:<br /># id weight type name up/down reweight<br />-1 5.22 root default<br />-2 1.8 host ceph-node1<br />0 0.8 osd.0 down 0 <br />2 0.91 osd.2 down 0 <br /><br />Is there any other ways to start an OSD? I'm out of ideas. What we do is we execute the ceph-deploy activate command to make an OSD as UP. Is that the right way to do it? We are using ceph version 0.80.4 <br /><br />Thanks!<br /><br />Regards,<br />Pons<br /><br /></pre>
