            Bug ID: 1168897
           Summary: Attempt remove-brick after node has terminated in
                    cluster gives error: volume remove-brick commit force:
                    failed: One or more nodes do not support the required
                    op-version. Cluster op-version must atleast be 30600.
           Product: GlusterFS
           Version: 3.6.1
         Component: core
          Severity: high

One node failed/terminated in a 2 node cluster with volumes replicated across
the 2 nodes.
When attempt to remove bricks associated with the now now-existent node it
fails as below:
gluster volume remove-brick gv_bmo replica 1 10.110.25.137:/data/brick/gv_bmo
force
Removing brick(s) can result in data loss. Do you want to Continue? (y/n) y
volume remove-brick commit force: failed: One or more nodes do not support the
required op-version. Cluster op-version must atleast be 30600.

If I attach a new node to the cluster (with same OS version and glusterfs
package versions (all components 3.6.1-1.el7.x86_64 ). And try to add a brick
to the volume a similar error is reported:

 gluster vol add-brick gv_bmo replica 3 10.110.25.243:/data/brick/gv_bmo volume
add-brick: failed: One or more nodes do not support the required op-version.
Cluster op-version must atleast be 30600.

The removal of bricks in same manner worked previously with 3.5.1.


Version-Release number of selected component (if applicable):

glusterfs-libs-3.6.1-1.el7.x86_64
glusterfs-3.6.1-1.el7.x86_64
glusterfs-server-3.6.1-1.el7.x86_64
glusterfs-api-3.6.1-1.el7.x86_64
glusterfs-fuse-3.6.1-1.el7.x86_64
glusterfs-cli-3.6.1-1.el7.x86_64



How reproducible:


Steps to Reproduce:
1. Set up volume replicated across bricks on 2 nodes
2. Shutdown one node
3. Try to remove the brick associated with failed node.

Actual results:
failed: One or more nodes do not support the required op-version. Cluster
op-version must atleast be 30600.

Expected results:
