-#. [AArch64 specific] Configure MySQL WSREP SST provider
-
- **NOTE**: This option is only available for ArmbandFuel@OPNFV, since it
- currently only affects AArch64 targets (see *Reference 15*).
-
- When using some AArch64 platforms as controller nodes, WSREP SST
- synchronisation using default backend provider (xtrabackup-v2) might fail,
- so a mechanism that allows selecting a different WSREP SST provider
- has been introduced.
-
- In the FUEL UI of your Environment, click the <Settings> tab, click
- <OpenStack Services> on the left side pane (see figure below), then
- select one of the following options:
-
- - xtrabackup-v2 (default provider, AArch64 stability issues);
-
- - rsync (AArch64 validated, better or comparable speed to xtrabackup,
- takes the donor node offline during state transfer);
-
- - mysqldump (untested);

-Subject: [PATCH] Allow configuring MySQL WSREP SST provider
-
-On some arm64 platforms xtrabackup is broken due to an outdated
-MySQL/InnoDB code that it uses which is missing. To work around that
-this patch allows choosing which WSREP SST provider to use. Aside of
-already supported `xtrabackup-v2` and `mysqldump`, the `rsync` method
-has been added as it is comparable to xtrabackup in terms of speed (or
-is faster), has been validated to work on arm64 platforms where
-xtrabackup is broken and it doesn't rely on db mechanisms to perform the
-state transfer.
-
-This patch is tied to a patch in fuel-web that introduces configuration
-options for WSREP SST provider and in case nothing is specified, it
-will choose `xtrabackup-v2`.
