What: /sys/bus/rbd/add
|
|
Date: Oct, 2010
|
|
KernelVersion: v2.6.37
|
|
Contact: Sage Weil <sage@newdream.net>
|
|
Description:
|
|
(WO) Add rbd block device.
|
|
|
|
Usage: <mon ip addr> <options> <pool name> <rbd image name> [<snap name>]
|
|
|
|
Example::
|
|
|
|
$ echo "192.168.0.1 name=admin rbd foo" > /sys/bus/rbd/add
|
|
|
|
The snapshot name can be "-" or omitted to map the image
|
|
read/write. A <dev-id> will be assigned for any registered block
|
|
device. If snapshot is used, it will be mapped read-only.

|
|
Description:
|
|
(WO) Remove rbd block device.
|
|
|
|
Usage: <dev-id> [force]
|
|
|
|
Example::
|
|
|
|
$ echo 2 > /sys/bus/rbd/remove
|
|
|
|
Optional "force" argument which when passed will wait for
|
|
running requests and then unmap the image. Requests sent to the
|
|
driver after initiating the removal will be failed. (August
|
|
2016, since 4.9.)

/sys/bus/rbd/add if /sys/bus/rbd/add_single_major is available
