Oracle VM: Attempting to refresh a File Server in the OVM GUI fails with "RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)\n' " (Doc ID 2055365.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle VM - Version 3.0.1 and later
Linux x86-64

Symptoms

 On Oracle VM, when Attempting to refresh a NFS file server located on a Linux Server (e.g. a NFS server running Oracle Linux 6.7), the refresh job fails with the following kind of error message in the manager :

OVMAPI_B000E Storage plugin command [storage_plugin_listFileSystems] failed for storage server [0004fb0000090000b4966a45aeb23134] failed with [com.oracle.ovm.mgr.api.exception.FailedOperationException: OVMAPI_4010E Attempt to send command: storage_plugin_listFileSystems to server: ovs1 failed. OVMAPI_4004E Sync command failed on server: 10.x.x.x. Command: storage_plugin_listFileSystems, Server error: <class 'OSCPlugin.OperationFailedEx'>:'Unable to access file system at 10.x.x.x: clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)\n' [Sun Sep 13 17:08:00 CEST 2015] [Sun Sep 13 17:08:00 CEST 2015]] OVMAPI_4010E Attempt to send command: storage_plugin_listFileSystems to server: ovs2 failed. OVMAPI_4004E Sync command failed on server: 10.x.x.x. Command: storage_plugin_listFileSystems, Server error: org.apache.xmlrpc.XmlRpcException: <class 'OSCPlugin.OperationFailedEx'>:'Unable to access file system at 10.x.x.x: clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)\n' [Sun Sep 13 17:08:00 CEST 2015] [Sun Sep 13 17:08:00 CEST 2015] [Sun Sep 13 17:08:00 CEST 2015]

 This `no route to host` error is rather surprising, especially when considering that the VM server and the NFS server reply to each other's ping requests.

 The nfs service is however running on the NFS server - this can be verified with :

 # service nfs status 

 When run from the server, the following command successfully lists the shares on the server :

 # showmount -e 10.x.x.x

Attempting to telnet on the NFS ports on the NFS ports fails, e.g. the following command fails :

 # telnet 10.x.x.x 111
