ZFS Hits an Important Milestone, Version 0.6.1 Released 99
sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"
Attaching a non-rc version number... (Score:2, Informative)
does not a milestone make. Looking at this issue list - https://github.com/zfsonlinux/zfs/issues - makes me wary to even consider zfs on linux for any serious work.
Kernel panics, deadlocks, data corruption; not really things you'd want.

I've had 6 production ZFS servers under heavy load for over a year (FreeBSD 9.0-RC -> 9.1-RELEASE) without any problems. I've started building all of my new servers with root-on-zfs to start taking advantage of beadm (boot environments, lets you do a clone of your root file system, do an upgrade in a jail, then try booting off it, and then decide if you want to keep it, or roll back)

ZFS runs great on FreeBSD as well.

Yes [berkeley.edu].

Version 5000 is used for community ZFS implementations that have feature flags (Illumos, BSD, and Linux).
If you're talking about Solaris, the current version is 34; any version past 28 comes after Oracle closed off Solaris. Note that beyond version 28, the community and Oracle ZFS pools are not interoperable.
Re:Legal Issues? (Score:3, Informative)
Sort of, but it's different than you are thinking. Linux is licensed under the GPL 2, while ZFS is licensed under CDDL. Those two licenses are not compatible. Since the GPL is a distribution license, not a use license, there is nothing stopping you from using ZFS on Linux. However, you can't ship the two combined as you would then be violating the license. The practical effect is that you won't ever see a kernel implementation of ZFS ship with a Distro unless oracle relicenses ZFS. You'll have to download, compile, and install ZFS yourself for the Linux-based computers that you want to use it on. And that's perfectly legal within the scope of the licenses.

Snapshots, volumes, checksums, easy expansion, better drive management, shorter recovery time when the system crashes, etc etc etc. ZFS is so far ahead of ext4 they are in completely different fields. ZFS works well on low resource machines too. I use it on a small home server with 512MB of RAM and it's been running great for over a year.
