Description
Hi,
We just upgrade our DB cluster to MariaDB 10.5.12. Found below unexpected Galera desync when using "backup stage block_commit" command. We leverage storage technology for backup. Backup stage commands are used to ensure data consistency in snapshot.
Rejoin cluster when running "backup stage end".
mysql> backup stage start ;
<<no message in error log which is normal>>
mysql> backup stage block_commit ;
