The State of ZFS On Linux

An anonymous reader writes: Richard Yao, one of the most prolific contributors to the ZFSOnLinux project, has put up a post explaining why he thinks the filesystem is definitely production-ready. He says, "ZFS provides strong guarantees for the integrity of [data] from the moment that fsync() returns on a file, an operation on a synchronous file handle is returned or dirty writeback occurs (by default every 5 seconds). These guarantees are enabled by ZFS' disk format, which places all data into a Merkle tree that stores 256-bit checksums and is changed atomically via a two-stage transaction commit.. ... Sharing a common code base with other Open ZFS platforms has given ZFS on Linux the opportunity to rapidly implement features available on other Open ZFS platforms. At present, Illumos is the reference platform in the Open ZFS community and despite its ZFS driver having hundreds of features, ZoL is only behind on about 18 of them."

No thanks, I'll stick with ReiserFS

It's a killer file system. Once you've used it, you won't be able to leave it.

Dedup easily needs 5GB of RAM per TB.

For general usage (no dedup), 1GB per TB is a good rule of thumb.

This. Don't starve the ARC. You wouldn't like it when it's angry.
