Network error if no up servers found. Sahina please confirm. Second issue is expected behavior from glusterfs that if you used a directory as brick then gluster will not allow to create volume with the same brick.(vdsm logs shows the same) No, the VDS_NETWORK_ERROR is not related to UP server. This is in the log: 2013-10-04 04:51:21,725 ERROR [org.ovirt.engine.core.vdsbroker.gluster.CreateGlusterVolumeVDSCommand] (ajp-/127.0.0.1:8702-10) Command CreateGlusterVolumeVDS execution failed. Exception: VDSNetworkException: org.apache.xmlrpc.XmlRpcException: <type 'exceptions.TypeError'>:sequence item 0: expected string, NoneType found related to : GlusterVolumeCreateFailedException: <unprintable GlusterVolumeCreateFailedException object> This issue is not seen in CB8. If it's not seen in CB9, we can close it. Not able to recreate in CB9. Closing the BZ. |
