man aoe-mkshelf (Administration système) - create special device files for one shelf address

NAME

aoe-mkshelf - create special device files for one shelf address

SYNOPSIS

aoe-mkshelf {device-dir} {shelf-address}
env n_partitions=1 aoe-mkshelf {device-dir} {shelf-address}

DESCRIPTION

The aoe-mkshelf command uses mknod to create the block special files necessary to access the AoE devices with the given shelf address.

If your aoe driver supports only one partition per device (whole-disk partitions), then the device files must match, and you should use the n_partitions environment variable described below.

Arguments

device-dir
This should be the name of the directory where the block device files will be created.
shelf-address
This is the AoE major address, or shelf address, for which to create device nodes. For example, specifying a shelf address of 1 means that the e1.* device nodes will be created in device-dir.

ENVIRONMENT VARIABLES

If the n_partitions variable is set in the environment, it will override the default number of partitions per aoe disk, namely 16.

EXAMPLE

In this example, the root user on a host named nai creates special files for using the aoe disks in shelf 7. Then he remembers that the driver doesn't have partition support, so the command is called again with n_partitions set to 1.

nai:~# aoe-mkshelf /dev/etherd 7 nai:~# ls /dev/etherd/e7.* | wc -l 160 nai:~# rm /dev/etherd/e7.* nai:~# n_partitions=1 aoe-mkshelf /dev/etherd 7 nai:~# ls /dev/etherd/e7.* | wc -l 10 nai:~#
