Known Problems in the ZFS FreeBSD port

Note that a much revised and newer port of ZFS exists in the 8.X series (8.1-RELEASE, 8.2-RELEASE) and 9-CURRENT, which has so far proven to be significantly better. Some parts of it were backported to 7-STABLE. Because of this, the list that was hosted on this page is obsolete. New items will appear here if problems in the new code are encountered.

• Note that i386 and other 32-bit architectures are still definitely not recommended for use with ZFS due to address space issues.

• tmpfs(5) isn't recommended for use with ZFS because it can suddenly run out of space due to interaction with the ZFS ARC. http://lists.freebsd.org/pipermail/freebsd-stable/2011-January/060867.html
