aoe-mkdevs - create special device files for aoe driver
aoe-mkdevs {device-dir}env n_partitions=1 aoe-mkdevs {device-dir}
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.
- device-dir
- This should be the name of the directory where
the special device files will be created.
If the n_partitions
variable is set in the environment, it will override the default number
of partitions per aoe disk, namely 16.
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.
