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 is deprecated in favor of udev. Systems with
udev do not need to use the aoe-mkdevs or aoe-mkself commands, because
udev will create device nodes as needed.
Systems without udev use aoe-mkdevs to create the character special
files necessary to control the aoe driver. The aoe-mkdevs command uses
aoe-mkshelf to also create block special files.
The aoe drivers after version 49 support dynamic minor device numbers
so that a greater number of devices can be supported. The aoe-mkdevs
command is incompatible with dynamic device numbers. If your system
lacks udev, and you are using an aoe driver version 50 or above, use
the aoe_dyndevs=0 module option to force the aoe driver to use static
device numbers.
If you are not using dynamic device numbers, and you built your aoe
driver to support 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

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