Linux ZFS: Almost Good

As you know, ZFS support is missing in the Linux kernel due to licensing issues. However, the ZFS-FUSE project exists (although it does not develop at all).

This implementation is based on the user-space (FUSE) file system rendering. Thus, the code itself is not entered into the kernel and the license does not contradict.

It consists of a daemon (zfs-fused), management utilities (zfs, zpool, zdump, etc.) and a fuse module.

I decided to install it for the sake of the test. Installed. Work. :)



To begin with - installation.

The source code of the project is open, download and can be from here .
The latest stable version is 0.5.0. There are .deb and ebuild packages in the Gentoo tree.

With the assembly and installation of problems did not arise, with the launch - too.

Tests

Under tests, I selected a whole section on the screw; I performed the mirroring tests in the pool created from the files.

Fully work:

• Arrays
• Mirroring
• Creating and restoring snapshots
• FS cloning
• Compression (lzo and gzip supported)
• Connect and disconnect FS
• Connect and disconnect devices
• FS check

Does not work:

• Send and receive
• If the daemon is disconnected incorrectly, there are problems with pool reconnection.

Work buggy:

• The demon itself (sometimes freezes on shutdown and waits for the kill).
• Quota
• Rights level FS.

Conclusion : you can use, though carefully. However, the project is actually frozen, changes are rarely made :(
