<p>Hi All,</p>
<p>I have a problem and I hope that someone can help me.</p>
<p>I have a 3 node cluster with Proxmox 4.4 and DRBD 9.06.1 with drbdmanage 0.99.4 working in production from 2016 and for some reason I don't like to update to the new version for the moment .</p>
<p>Now Proxmox is still working but DRBD not more, these are the situation and the errors:</p>
<p>root@mpve2:/etc/drbd.d# drbdadm status<br />.drbdctrl role:Secondary<br />volume:0 disk:Outdated<br />volume:1 disk:UpToDate<br />mpve1 role:Secondary<br />volume:0 peer-disk:Outdated<br />volume:1 peer-disk:UpToDate<br />mpve3 role:Secondary<br />volume:0 peer-disk:Outdated<br />volume:1 peer-disk:UpToDate</p>
<p>root@mpve2:~# drbdmanage list-nodes<br />Waiting for server: ...............<br />Error: Startup not successful (no quorum? not *both* nodes up in a 2 node cluster?)<br />No nodes defined</p>
<p>and trying:</p>
<p>root@mpve2:~# systemctl enable drbd<br />Synchronizing state for drbd.service with sysvinit using update-rc.d...<br />Executing /usr/sbin/update-rc.d drbd defaults<br />Executing /usr/sbin/update-rc.d drbd enable<br />update-rc.d: error: drbd Default-Start contains no runlevels, aborting.</p>
<p>more:</p>
<p>root@mpve2:/var/lib/pve-cluster# drbdmanage a</p>
<p>Error: Cannot connect to the drbdmanaged process using DBus<br />The DBus subsystem returned the following error description:<br />org.freedesktop.DBus.Python.TypeError: Traceback (most recent call last):<br />File "/usr/lib/python2.7/dist-packages/dbus/service.py", line 751, in _message_cb<br />_method_reply_return(connection, message, method_name, signature, *retval)<br />File "/usr/lib/python2.7/dist-packages/dbus/service.py", line 254, in _method_reply_return<br />reply.append(signature=signature, *retval)<br />TypeError: 'int' object is not iterable</p>
<p>How can I restore RBD operation? (I can, if necessary, remove all the VM as I have backups).</p>
<p>Thanks in advance,</p>
<p>Michele</p>
