This fork exists as a workaround to a specific problem I was having. I had a drive fail with 512 byte sector size, and the replacement that I purchased had 4K sectors. This would lead to an error in the zpool replace command:

sudo zpool replace tank oldDisk newDisk -f
cannot replace oldDisk with newDisk: devices have different sector alignment

I patched the code to use the logical sector size instead of the physical sector size, which then allowed the replacement to succeed.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg

To copy the kernel code inside your kernel source tree for builtin compilation:

$ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
$ ./copy-builtin /usr/src/linux-...

Full documentation for building, configuring, and using ZFS can be found at: http://zfsonlinux.org
