NAME
ccd.conf -- concatenated disk driver configuration file SYNOPSIS
ccd.conf DESCRIPTION
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. 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. FILES

NAME
ccdconfig -- configuration utility for the concatenated disk driver SYNOPSIS
ccdconfig [-cv] ccd ileave [flags] dev [...] ccdconfig -C [-v] [-f config_file] ccdconfig -u [-v] ccd [...] ccdconfig -U [-v] [-f config_file] ccdconfig -g [-M core] [-N system] [ccd [...]] DESCRIPTION
ccdconfig is used to dynamically configure and unconfigure concatenated disk devices, or ccds. For more information about the ccd, see ccd(4). The options are as follows: -c Configure a ccd. This is the default behavior of ccdconfig. -C Configure all ccd devices listed in the ccd configuration file. -f config_file When configuring or unconfiguring all devices, read the file config_file instead of the default /etc/ccd.conf. -g Dump the current ccd configuration in a format suitable for use as the ccd configuration file. If no arguments are specified, every configured ccd is dumped. Otherwise, the configuration of each listed ccd is dumped. -M core Extract values associated with the name list from core instead of the default /dev/mem. -N system Extract the name list from system instead of the default /netbsd. -u Unconfigure a ccd. -U Unconfigure all ccd devices listed the ccd configuration file. -v Causes ccdconfig to be verbose. A ccd is described on the command line and in the ccd configuration file by the name of the ccd, the interleave factor, the ccd configuration flags, and a list of one or more devices. The flags may be represented as a decimal number, a hexadecimal number, a comma-separated list of strings, or the word ``none''. The flags are as follows: Symbolic Numeric Comment CCDF_UNIFORM 0x02 Use uniform interleave. The size of all components is clamped to that of the smallest component. CCDF_NOLABEL 0x04 Ignore raw disklabel. Useful when creating a new ccd. /etc/ccd.conf The file /etc/ccd.conf is used to configure ccdconfig if -C or -U is used. Each line of the configuration file contains arguments as per the -c argument: ccd ileave [flags] dev [...] 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. See EXAMPLES for an example of /etc/ccd.conf. FILES
/etc/ccd.conf - default ccd configuration file. EXAMPLES
The following command, executed from the command line, would configure ccd0 with 4 components (/dev/sd2e, /dev/sd3e, /dev/sd4e, /dev/sd5e), and an interleave factor of 32 blocks. # ccdconfig ccd0 32 0 /dev/sd2e /dev/sd3e /dev/sd4e /dev/sd5e 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 SEE ALSO
