We've actually been running MySQL on ZFS on Solaris for quite some
time. :) We're very comfortable with that setup.
My question is more specific to live experience with doing the same
thing on FreeBSD. We know where the sabots are on MySQL/ZFS/Solaris.
Would like to find out where the landmines are when you swap Solaris
for FreeBSD in that equation.
Thank you again.
