After over 3 decades of experience with 'exportfs' being totally safe to run in real time with both userspace and kernel NFSD implementations, it came as quite a surprise when we did 'mmnfs eport change --nfsadd='... and it bounced the NFS server on all 4 protocol nodes. At the same time. Fortunately for us, the set of client nodes only changes once every 2-3 months.
