This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Storage Functions: OSDs and SSD-backed Journals
|
|
===============================================
|
|
|
|
Disks on storage hosts are assigned storage functions in |prod| to provide
|
|
either OSD storage or Ceph journal storage.
|
|
|
|
Rotational disks on storage hosts are always assigned as object storage
|
|
devices (OSDs) to provide storage for Application disks. Solid-state disks
|
|
\(SSDs) can be assigned as OSDs, or as journal functions to provide space for
|
|
Ceph transaction journals associated with OSDs. NVMe-compatible SSDs are also
|
|
supported.
|
|
|
|
To assign storage-host disks as OSDs, see :ref:`Provision Storage on a
|
|
Controller or Storage Host Using Horizon
|
|
<provision-storage-on-a-controller-or-storage-host-using-horizon>`.
|
|
|
|
To create SSD-backed journals, see :ref:`Add SSD-Backed Journals Using
|
|
Horizon <add-ssd-backed-journals-using-horizon>`.
