Problem creating simultaneous OpenStack cinder backups

Solution In Progress - Updated -

Issue

  • Unable to create several cinder backups (e.g. 20) using cinder backup-create command. Receiving this error:
Timed out waiting for a reply to message ID 6e0c4bf321254534b8b76434323f1faf
  • Increasing the value of rpc_response_timeout from 60 to 120 in /etc/cinder/cinder.conf results in a different error:
      ERROR oslo_messaging.rpc.dispatcher DBConnectionError: (pymysql.err.OperationalError) (2013, 'Lost connection to MySQL server during query')
  • When using a script calling cinder backup-create to create the backup, it fails with Lost connection to MySQL server during query
