Replace OSDs and Journal Disks
|
|
==============================
|
|
|
|
You can replace failed storage devices on storage nodes.
|
|
|
|
.. rubric:: |context|

|
|
|
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 standard, |AIO-SX|, and |AIO-DX| systems, use the following
|
|
alternative procedures to replace |OSDs| without reinstalling the host:

Follow the procedure located at |node-doc|: :ref:`Change

|
|
storage host is unlocked.
