ccd.conf — concatenated disk driver configuration file

ccd.conf

The ccd.conf file defines the configuration of concatenated disk devices, or ccds. It is used by ccdconfig(8) when invoked with the -C option and at system boot time. For more information about the concatenated disk driver, see ccd(4).

Each line of the configuration file contains arguments as per the -c argument to ccdconfig(8):

ccd ileave [flags] dev [...]
ccd
The name of the ccd.
ileave
The interleave, expressed in units of DEV_BSIZE. For serial concatenation, specify ‘0’.
flags
The flags for the device, which may be represented as a decimal number, a hexadecimal number, a comma-separated list of strings, or the word “none”.
dev [...]
The component partitions to be concatenated, which should be of type FS_CCD.

A ‘#’ is a comment, and everything to end of line is ignored. A ‘\’ at the end of a line indicates that the next line should be concatenated with the current. A ‘\’ preceding any character (other than the end of line) prevents that character's special meaning from taking effect.

/etc/ccd.conf

An example /etc/ccd.conf:

#
# /etc/ccd.conf
# Configuration file for concatenated disk devices
#

# ccd           ileave  flags   component devices
ccd0            16      none    /dev/sd2e /dev/sd3e

The ccd.conf configuration file first appeared in NetBSD 1.1.
