Remount all NFS mounts to another cluster IP

mount | grep 10.0.0.73 | cut -f3 -d\  | xargs mount -o remount,rw,rsize=32768,wsize=32768,nfsvers=3,bg,intr,tcp,retrans=0,addr=10.0.0.74

Not much to say. This seems to work even when the disk is in use. Using it with Isilon to remount off of a quiesced node.
