What: /sys/bus/rbd/add |
|
Date: Oct, 2010 |
|
KernelVersion: v2.6.37 |
|
Contact: Sage Weil <[email protected]> |
|
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. |

What: /sys/bus/rbd/remove |
|
Date: Oct, 2010 |
|
KernelVersion: v2.6.37 |
|
Contact: Sage Weil <[email protected]> |
|
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.) |

What: /sys/bus/rbd/add_single_major |
|
Date: Dec, 2013 |
|
KernelVersion: v3.14 |
|
Contact: Sage Weil <[email protected]> |
|
Description: |
|
(WO) Available only if rbd module is inserted with single_major |
|
parameter set to true. |
|
|
|
Usage is the same as for /sys/bus/rbd/add. If present, this |
|
should be used instead of the latter: any attempts to use |
|
/sys/bus/rbd/add if /sys/bus/rbd/add_single_major is available |
|
will fail for backwards compatibility reasons. |

unsupported features that need to be disabled. |
