I feel like we're being hung out to dry here. I've got 70TB on 9
various Solaris 10 u4 servers, with different data sets. All of these
are NFS servers. Two servers have a ton of small files, with a lot of
read and write updating, and NFS performance on these are abysmal. ZFS
is installed on SAN array's (my first mistake). I will test by
disabling the ZIL, but if it turns out the ZIL needs to be on a separate
device, we're hosed.
Before ranting any more, I'll do the test of disabling the ZIL. We may
have to build out these systems with Open Solaris, but that will be hard
as they are in production. I would have to install the new OS on test
systems and swap out the drives during scheduled down time. Ouch.
