Description:
Help message is not formatted properly.
How to repeat:
Execute the "mysqlfabric help group command". For example,
$ mysqlfabric help group promote
group promote group_id [--SLAVE_UUID=NONE] [--UPDATE_ONLY=FALSE] [--SYNCHRONOUS=TRUE]
Promote a server into master.
If users just want to update the state store and skip provisioning
steps such as configuring replication, the update_only parameter
must be set to true. Otherwise, the following happens.
If the master within a group fails, a new master is either
automatically or manually selected among the slaves in the group.
The process of selecting and setting up a new master after
detecting that the current master failed is known as failover.
It is also possible to switch to a new master when the current one is
still alive and kicking. The process is known as switchover and
may be used, for example, when one wants to take the current
master off-line for maintenance.
If a slave is not provided, the best candidate to become the new
master is found. Any candidate must have the binary log enabled,
should have logged the updates executed through the SQL Thread and
both candidate and master must belong to the same group. The
smaller the lag between slave and the master the better. So the
candidate which satisfies the requirements and has the smaller lag
is chosen to become the new master.
In the failover operation, after choosing a candidate, one makes the
slaves point to the new master and updates the state store setting
the new master.
In the switchover operation, after choosing a candidate, any write
access to the current master is disabled and the slaves are
synchronized with it. Failures during the synchronization that do
not involve the candidate slave are ignored. Then slaves are
stopped and configured to point to the new master and the state
store is updated setting the new master.
