Quoting Toby Corkindale (toby.corkindale@strategicdata.com.au):
I've been giving ZFS a bit of a trial run on one of my servers, because the block-based deduplication looked attractive, as did the checksumming and using an SSD as L2 cache.
Unfortunately I ended up giving up -- it *seemed* pretty good on the surface, but I managed to kill the server too often.
If I were to deploy ZFS for any important deployment, personally I'd use Nexenta for that: OpenSolaris kernel, almost entirely GNU userspace. It appears to be extremely reliable for that purpose. -- Rick Moen "Do not be afraid to use exclamation points rick@linuxmafia.com in your writing. They can sense fear." McQ! (4x80) -- FakeAPStylebook
