Description of problem:
I had an EXT/NFS service running on taft-03 and a NFS client doing I/O to that
service on joynter. I then successfully relocated that service to taft-02 and
that caused I/O errors on the client.

[root@taft-02 ~]# clusvcadm -r EXT10 -m taft-02
Trying to relocate EXT10 to taft-02...success

Version-Release number of selected component (if applicable):
[root@taft-02 ~]# rpm -q rgmanager
rgmanager-1.9.44-0


How reproducible:
everytime

Here's my .conf file...
