-------- Original Message -------- Subject: [ovirt-users] (no subject) Date: Mon, 24 Nov 2014 14:12:55 -0500 From: Alastair Neil <ajneil.tech(a)gmail.com&gt; To: Ovirt Users <users(a)ovirt.org&gt; I see frequents errors in the vdsm log on one of the gluster servers in my gluster cluster. Can anyone suggest a way to troubleshoot this,  the host is fine in the ovirt console and gluster functions ok. The Gluster cluster is a replica 2, with 2 hosts. I am trying to add another host to move to replica 3 but having trouble and this error seems to cause any  changes to the cluster to fail with unexpected errors in ovirt. -Thanks, Alastair Gluster Server VentOS 6.6: vdsmd: vdsm-4.16.7-1.gitdb83943.el6 gluster: glusterfs-3.6.1-1.el6 ovirt host Fedora 20: hosted ovirt-engine 3.5.0.1-1 Thread-53::DEBUG::2014-11-24 14:11:45,362::BindingXMLRPC::1132::vds::(wrapper) client [xxx.xxx.xxx.39]::call hostsList with () {} Thread-53::ERROR::2014-11-24 14:11:45,363::BindingXMLRPC::1151::vds::(wrapper) unexpected error Traceback (most recent call last):  File "/usr/share/vdsm/rpc/BindingXMLRPC.py", line 1135, in wrapper   res = f(*args, **kwargs)  File "/usr/share/vdsm/gluster/api.py", line 54, in wrapper   rv = func(*args, **kwargs)  File "/usr/share/vdsm/gluster/api.py", line 251, in hostsList   return {'hosts': self.svdsmProxy.glusterPeerStatus()}  File "/usr/share/vdsm/supervdsm.py", line 50, in __call__   return callMethod()  File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda>   **kwargs)  File "<string>", line 2, in glusterPeerStatus  File "/usr/lib64/python2.6/multiprocessing/managers.py", line 725, in _callmethod   conn.send((self._id, methodname, args, kwds)) IOError: [Errno 32] Broken pipe Thread-53::DEBUG::2014-11-24 14:03:08,721::BindingXMLRPC::1132::vds::(wrapper) client [xxx.xxx.xxx.39]::call volumesList with () {} Thread-53::ERROR::2014-11-24 14:03:08,721::BindingXMLRPC::1151::vds::(wrapper) unexpected error Traceback (most recent call last):  File "/usr/share/vdsm/rpc/BindingXMLRPC.py", line 1135, in wrapper   res = f(*args, **kwargs)  File "/usr/share/vdsm/gluster/api.py", line 54, in wrapper   rv = func(*args, **kwargs)  File "/usr/share/vdsm/gluster/api.py", line 78, in volumesList   return {'volumes': self.svdsmProxy.glusterVolumeInfo(volumeName)}  File "/usr/share/vdsm/supervdsm.py", line 50, in __call__   return callMethod()  File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda>   **kwargs)  File "<string>", line 2, in glusterVolumeInfo  File "/usr/lib64/python2.6/multiprocessing/managers.py", line 725, in _callmethod   conn.send((self._id, methodname, args, kwds)) IOError: [Errno 32] Broken pipe
