hello. If you want to use zfs for your storage, which I strongly
recommend, lose the
zvols and use flat files inside zfs itself. I think you'll find your storage
performance goes
up by orders of magnetude. I struggled with this on FreeBSD for over a year
before I found the
myriad of tickets on google regarding the terrible performance of zvols. It's
a real shame,
because zvols are such a tidy way to manage virtual servers. However, the
performance penalty
is just too big to ignore.
