This chapter covers the use of disks under the GEOM framework in FreeBSD. This
includes the major RAID control utilities which use the framework for
configuration. This chapter will not go into in depth discussion on how GEOM handles or
controls I/O, the underlying subsystem, or code. This information is provided through the
geom(4) manual page
and its various SEE ALSO references. This chapter is also not a definitive guide to
RAID configurations. Only GEOM-supported RAID classifications will be discussed.
After reading this chapter, you will know:

RAID levels.

-
How to troubleshoot disks attached to the GEOM framework.
