+.Sh NAME
+.Nm ccd
+.Nd Concatenated disk driver
+.Sh SYNOPSIS
+.Cd pseudo-device ccd
+.Sh DESCRIPTION
+The
+.Nm
+driver provides the capability of combining one or more disks/partitions
+into one virtual disk.
+.Pp
+This document assumes that you're familiar with how to generate kernels,
+how to properly configure disks and pseudo-devices in a kernel
+configuration file, and how to partition disks.
+.Pp
+Note that the
+.Sq raw
+partitions of the disks
+.Pa must not
+be combined.
+Each component partition should be offset at least one cylinder
+from the beginning of the component disk.
+This avoids potential conflicts between the component disk's
+disklabel and the
+.Nm Ns 's
+disklabel.
+The kernel will only allow component partitions of type
+.Dv FS_CCD .
+But for now, it allows partition of all types since some port
+lacks support of an on-disk BSD disklabel.
+The partition of
+.Dv FS_UNUSED
+may be rejected because device driver of component disk will refuse it.
+.Pp
+In order to compile in support for the
+.Nm ,
+you must add a line similar
+to the following to your kernel configuration file:
+.Bd -unfilled -offset indent
+pseudo-device	ccd	# concatenated disk devices
+.Ed
+.Pp
+The
+.Nm Ns s
+are allocated dynamically as needed.
+.Pp
+A
+.Nm
+may be either serially concatenated or interleaved.
+To serially concatenate the partitions, specify the interleave factor of 0.
+.Pp
+If a
+.Nm
+is interleaved correctly, a
+.Dq striping
+effect is achieved, which can increase performance.
+.\" The optimum interleave factor is typically the size of a track,
+.\" see
+.\" .Dq sectors/track
+.\" value in
+.\" .Xr disklabel 8
+.\" output.
+Since the interleave factor is expressed in units of
+.Dv DEV_BSIZE ,
+one must account for sector sizes other than
+.Dv DEV_BSIZE
+in order to calculate the correct interleave.
+The kernel will not allow an interleave factor less than the size
+of the largest component sector divided by
+.Dv DEV_BSIZE .
+.Pp
+Note that best performance is achieved if all component disks have the same
+geometry and size.
+Optimum striping cannot occur with different disk types.
+.Pp
+Also note that the total size of concatenated disk may vary depending on
+the interleave factor even if the exact same components are concatenated.
+And an old on-disk disklabel may be read after interleave factor change.
+As a result, the disklabel may contain wrong partition geometry and
+will cause an error when doing I/O near the end of concatenated disk.
+.Pp
+There is a run-time utility that is used for configuring
+.Nm Ns s .
+See
+.Xr ccdconfig 8
+for more information.
+.Sh WARNINGS
+If just one (or more) of the disks in a non-mirrored
+.Nm
+fails, the entire file system will be lost.

+The concatenated disk driver was originally written at the University of Utah.
