Be warned though it's still unclear to me as to whether the RAIDZ corruption bug has been tracked down and fixed yet..

compression already works with zfs-fuse

Reminds me of the NSS storage in Netware, somethign I missed when we went all Microsoft 8) However we also still have some large Linux servers and potentially something like this could mean a change the file servers too as our major headache is growth in the user file stores. Need more space for user docs and profile, add another LUN from the SAN and add as pool storage. The quotering per folder would be really useful too. I also hope they add native encryption as well as compression to ZFS as ten it would be a perfect all round user data storage filesystem. (I think I'd still prefer safe old ext3 for / 8) If the write performance can be resolved then would be perfect for backup staging as well. This looks really impressive.

It's my understanding that ZFS outperforms software mirroring. By using a mirror as the basis for ZFS, you lose some of the built-in performance and reliability, making writes synchronous and forcing resyncs if power is lost. http://www.opensolaris.org/os/community/zfs/docs/zfs_last.pdf I wonder how different the tests would be if you didn’t run on an LVM mirror, and instead used ZFS to mirror.

Not even the official one. To be honest, I've lost interest in it on that system. If it's not portable enough to work on that then it's not ready for prime time.

Of course if Sun had used the GPLv2 or a compatible license rather than inventing a new GPL incompatible license we wouldn't have this problem.
