ccd.conf
—
concatenated disk driver configuration file
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.
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.
