man aoe-mkdevs (Administration système) - create special device files for aoe driver

NAME

aoe-mkdevs - create special device files for aoe driver

SYNOPSIS

aoe-mkdevs {device-dir}
env n_partitions=1 aoe-mkdevs {device-dir}

DESCRIPTION

The aoe-mkdevs command uses mknod to create the character special files necessary to control the aoe driver. It also uses aoe-mkshelf to create block special files.

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 special device files will be created.

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. After remembering that the driver doesn't have partition support, this sysadmin gets rid of the mismatching device nodes and calls aoe-mkdevs again with n_partitions set to 1.

nai:~# rm -rf /dev/etherd nai:~# aoe-mkdevs /dev/etherd nai:~# ls /dev/etherd | wc -l 1603 nai:~# rm -rf /dev/etherd nai:~# n_partitions=1 aoe-mkdevs /dev/etherd nai:~# ls /dev/etherd | wc -l 103
