box.info.ro_reason

box.info.ro_reason¶

Since 2.10.0. Show the current mode of an instance (writable or read-only). Contains nil if the instance is in writable mode. When the field is not nil, reports the reason why the instance is read-only.

Possible error reasons:

• election – the instance is not the leader. That is, box.cfg.election_mode is not off. See box.info.election for details.
• synchro – the instance is not the owner of the synchronous transaction queue. For details, see box.info.synchro.
• config – the server instance is in read-only mode. That is, box.cfg.read_only is true.
• orphan – the instance is in orphan state. For details, see the orphan status page.
