Hmm, presumably somebody at Sun doesn't agree with that assessment or you'd think they'd take them out :). Mounting/sharing by hand outside of the zfs framework does make a huge difference. It takes about 45 minutes to mount/share or unshare/unmount with the mountpoint and sharenfs zfs properties set, mounting/sharing by hand with SHARE_NOINUSE_CHECK=1 even just sequentially only took about 2 minutes. With some parallelization I could definitely see hitting that 10 seconds you mentioned, which would sure make my patch windows a hell of a lot shorter. I'll need put together a script and fiddle some with smf, joy oh joy, I need these filesystems mounted before the web server starts. Thanks much for the tip! I'm hoping someday they'll clean up the sharing implementation and make it a bit more scalable. I had a ticket open once and they pretty much said it would never happen for Solaris 10, but maybe sometime in the indefinite future for OpenSolaris... -- Paul B.
