I know that the argument will be that I should break up the single filesystem into multiple volumes, since then I can fine tune the options (snapshots, snap schedules, etc) per volume. That is all good, but when you start getting 100's of GB of data, sometimes it does not split cleanly (and updating the vfstab N clients becomes a chore, no matter how automated you have it (well, save for NIS, but who does that?)).
We do. It works. We're happy.
