New page

== zfs zvol ==

Have you noticed that you are replicating the code of ZFS ZVols? All these features are available in ZVols and they work on Linux just fine, and they work *today*.
(the talk page was inaccessible, sorry about this. Rudd-O)

-: 1. It's true, the ZFS (OpenZFS) yet not compatible with GPL and becouse of this don't come with the vanilla kernel. But the same can be said by OpenVZ code, even the code being compatible with GPL it is not accepted and implemented in vanilla version of the Kernel. So we still need to use modified versions of the Kernel to use all functions of OpenVZ, the same happens with the ZFS on Linux that we have to use a kmod to make it work. But this is even easier to implement and far more compatible than the OpenVZ itself.
