CCDCONFIG(8) NetBSD System Manager's Manual CCDCONFIG(8)
ccdconfig -- configuration utility for the concatenated disk driver
ccdconfig [-cv] ccd ileave [flags] dev [...] ccdconfig -C [-v] [-f config_file] ccdconfig -u [-v] ccd [...] ccdconfig -U [-v] [-f config_file] ccdconfig -g [ccd [...]]
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. -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. An interleave factor of 0 means that the devices are concatenated serially, not interleaved. 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 creat- ing 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.
/etc/ccd.conf - default ccd configuration file.
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
