RAIDframe has been been capable of autoconfiguration of components
originally configured on opposite endian systems. The current label
endianness will be retained.

.Pp
RAIDframe was ported to
.Nx
by Greg Oster in 1998, who has maintained it since.
In 1999, component labels, spares, automatic rebuilding of parity, and
autoconfiguration of volumes were added.
In 2000, root on RAID support was added (initially, with no support for
loading kernels from RAID volumes, which has been added to many ports since.)
In 2009, support for parity bimap was added, reducing parity resync time
after a crash.
In 2010, support for larger the 2TiB and non-512 sector devices was added.
In 2018, support for 32-bit userland compatibility was added.
In 2021, support for autoconfiguration from other-endian raid sets was added.
.Pp
Support for loading kernels from RAID 1 partitions was added for the
alpha, pmax and vax ports in 2000, the the sgimips port in 2001,
the x86 ports in 2003, the arc port in 2005, the landisk, sparc, and
sparc64 ports in 2006, the cobalt port in 2007, the ofppc port in 2008,
the bebox port in 2010, the emips port in 2011, and the sandpoint port
in 2012.

The
