ZFS can be installed by using instructions supplied on the Solid Run wiki, with caveats. Essentially, the steps are this:
cd / wget http://lundman.net/ftp/cubox/zfs-0.6.0-rc8.arm7.tar.gz tar -zxf zfs-0.6.0-rc8.arm7.tar.gz rm zfs-0.6.0-rc8.arm7.tar.gz ldconfig sh /usr/local/README.sh zpool status
under RedSleeve, however, "zpool status" returns the following error:
error while loading shared libraries: libnvpair.so.1: cannot open shared object file: No such file or directory
The solution here is to edit /etc/ld.so.conf - there should already be one line:
include /etc/ld.so.conf.d/*.conf
add this line:
/usr/local/lib #path to zfs shared libraries
then save and run ldconfig again
NOTE: README.sh loads the kernel modules needed for zfs to work. If you have to reboot or lose power, you should execute this script again or you will get missing module errors.
Once zfs is working, you can work with it, as per the ZFS Admin Guide
