The pool cannot be imported, because is formatted using an incompatible version

Question

I can't access my zfs pool on Debian as it's saying that my version is too old:

root@Microknoppix:~# zpool import
  pool: WD_4TB
    id: 12726205736285302822
 state: UNAVAIL
status: The pool is formatted using an incompatible version.
action: The pool cannot be imported.  Access the pool on a system running newer
    software, or recreate the pool from backup.
   see: http://www.sun.com/msg/ZFS-8000-A5
config:

    WD_4TB                                                       UNAVAIL  newer version
      disk/by-id/ata-WDC_WD40EZRX-00SPEB0_WD-WCC4E0184707-part1  ONLINE

In addition, the provided sun's link is broken.

I've installed the latest zfs-fuse via:

root@Microknoppix:~# apt-cache madison zfs-fuse
  zfs-fuse |   0.7.0-12 | http://ftp.de.debian.org/debian/ testing/main i386 Packages
  zfs-fuse |   0.7.0-12 | http://ftp.de.debian.org/debian/ unstable/main i386 Packages
  zfs-fuse |    0.7.0-8 | http://ftp.de.debian.org/debian/ stable/main i386 Packages
root@Microknoppix:~# apt-get install zfs-fuse=0.7.0-12
root@Microknoppix:~# zfs upgrade
This system is currently running ZFS filesystem version 4.

But upgrading didn't help much.

How I can access my pool or how to upgrade zfs to the recent version that would be compatible with above pool?

Answer 1

Uninstall zfs-fuse and install ZFS on Linux: http://zfsonlinux.org, and for Debian specifically: http://zfsonlinux.org/debian.html

The instructions from the links above are pretty straight forward, however, a couple of caveats I ran into that aren't mentioned:

• /etc/hostid file wasn't there which resulted in a failed initramfs image build, the fix is easy: hostid > /etc/hostid and choose to install maintainers /etc/hostid further in the process.

• make sure build-essential package is installed

• increase vmalloc size to at least 512M
