          <div>IIUC, you would essentially be unmounting the volume from

    Well yes.<br>

    You're right but when mounts are from fstab the volumes may be still
    busy at end of boot-time. There are solutions: update fstab before
    shutdown, mount volumes later, re-reboot after editing…<br>
    But being able to propagate a new local value to client config
    without umount/mount may be usefull.<br>

              </span> Thanks for that tip!<br>
              Just a question: as our clients can migrate beetween
              buildings (not often, but it happens), does using
              something like 'mount -o
              "remount,xlator-option=*replicate*.read-subvolume-index=X"
              …' will allow the client to point to the new target
              without stopping volume availability for clients?<br>
