Great . I will test and let you guys know how it goes. Meanwhile you guys can answer me a question.
a) I have a lun (gfs2) mounted to /test b) I replicate it c) I undefine my original lun from this cluster node d) I now assign the replicated lun to the same cluster node e) I issue a lip Since the luns are same in all aspects, will it automatically configure itself the new one and mount it to /test?
