You can replace failed storage devices on storage nodes.

|
For best results, ensure the replacement disk is the same size as others in
|
|
the same peer group. Do not substitute a smaller disk than the original.
|
|
|
|
.. note::
|
|
Due to a limitation in **udev**, the device path of a disk connected through
|
|
a SAS controller changes when the disk is replaced. Therefore, in the
|
|
general procedure below, you must lock, delete, and re-install the node.
|
|
However, for an |AIO-DX| system, use the following alternative procedure to
|
|
replace |OSDs| without reinstalling the host:
|
|
:ref:`Replace OSDs on an AIO-DX System <replace-osds-on-an-aio-dx-system-319b0bc2f7e6>`.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
Follow the procedure located at |node-doc|: :ref:`Change
|
|
Hardware Components for a Storage Host <changing-hardware-components-for-a-storage-host>`.
|
|
|
|
The replacement disk is automatically formatted and updated with data when the
|
|
storage host is unlocked.
