Unfortunately migration is not working in platform setup. Please test with platform iso image. Behavior is appearing in "glusterfs 3.1.1qa7" also. PATCH: http://patches.gluster.com/patch/5719 in master (rpc-clnt: move rpc_clnt_reconnect() call to rpc_clnt_init) PATCH: http://patches.gluster.com/patch/5720 in master (rpc-clnt: introduce new way of creating rpc-clnt objects) PATCH: http://patches.gluster.com/patch/5721 in master (protocol/client: use the new rpc_clnt initialization methods) Behavior is appearing in "glusterfs 3.1.1qa8" also.
I followed the below steps in platform server:
Creation of volume test has been successful
[root@t1 ~]# gluster volume start test
Starting volume test has been successful
[root@t1 ~]# mount -t nfs -o nolock t1:/test /tmp/test

chacked with glusterfs-3.1.1, glusterfs-3.1.2 and latest git (26cedae57d5b7cb8d50ed077ce29c92e30d6e260). Migration is working fine. |
