Type: unix-block
¶
Note
The unix-block
device type is supported for containers.
It supports hotplugging.
Unix block devices make the specified block device appear as a device in the instance (under /dev
).
You can read from the device and write to it.
Device options¶
unix-block
devices have the following device options:
Key: | required |
Type: | bool |
Default: |
|
See Hotplugging for more information.
Configuration examples¶
Add a unix-block
device to an instance by specifying its source and path:
lxc config device add <instance_name> <device_name> unix-block source=<path_on_host> path=<path_on_instance>
If you want to use the same path on the instance as on the host, you can omit the source
option:
lxc config device add <instance_name> <device_name> unix-block path=<path_to_the_device>
See Configure devices for more information.
Hotplugging¶
Hotplugging is enabled if you set required=false
and specify the source
option for the device.
In this case, the device is automatically passed into the container when it appears on the host, even after the container starts. If the device disappears from the host system, it is removed from the container as well.
