<p style="margin-bottom: 0; margin-top: 0">
<font size="2" face="Dialog">After search some articles and mailing list and try my best, my ceph datastore can't monitor the capacity. </font> </p>

<font size="2" face="Dialog">1) How can opennebula detect the size of ceph?</font> </p>
<p style="margin-bottom: 0; margin-top: 0">
<font size="2" face="Dialog"> - Opennebula is a ceph-mon?</font> </p>
<p style="margin-bottom: 0; margin-top: 0">
<font size="2" face="Dialog"> If yes, how can oneadmin user can run the rados command to show the capacity, only root can do that? It must be "sudo rados", right? </font> </p>
<br>
<p style="margin-bottom: 0; margin-top: 0">
<font size="2" face="Dialog"> - The opennebula accesses to ceph-mon(font-end) with password-less to run "ssh ho-srv-ceph-02 rados df | grep Total"</font> </p>
<p style="margin-bottom: 0; margin-top: 0">
<font size="2" face="Dialog"> If yes, i need an user oneadmin in ceph-mon and ability to run rados df without sudo, so how? only root can run rados in this case.</font> </p>
