通过数据库修改trove instance status

Posted 2020-09-07

由于测试mysql5.5的复制功能，默认trove使用gtid，instance 一直处于 BACKUP 状态，trove reset-status 不能在 BACKUP 状态下运行，手动修改数据库

修改 service_statuses 表中 status_id 字段为 0x16，十进为22

状态码查看文件

# trove/common/instance.py 97行
class ServiceStatuses(object):
    RUNNING = ServiceStatus(0x01, ‘running‘, ‘ACTIVE‘)
    BLOCKED = ServiceStatus(0x02, ‘blocked‘, ‘BLOCKED‘)
    PAUSED = ServiceStatus(0x03, ‘paused‘, ‘SHUTDOWN‘)
    SHUTDOWN = ServiceStatus(0x04, ‘shutdown‘, ‘SHUTDOWN‘)
    CRASHED = ServiceStatus(0x06, ‘crashed‘, ‘SHUTDOWN‘)
    FAILED = ServiceStatus(0x08, ‘failed to spawn‘, ‘FAILED‘)
    BUILDING = ServiceStatus(0x09, ‘building‘, ‘BUILD‘)
    PROMOTING = ServiceStatus(0x10, ‘promoting replica‘, ‘PROMOTE‘)
    EJECTING = ServiceStatus(0x11, ‘ejecting replica source‘, ‘EJECT‘)
    LOGGING = ServiceStatus(0x12, ‘transferring guest logs‘, ‘LOGGING‘)
    UNKNOWN = ServiceStatus(0x16, ‘unknown‘, ‘ERROR‘)
    NEW = ServiceStatus(0x17, ‘new‘, ‘NEW‘)
    DELETED = ServiceStatus(0x05, ‘deleted‘, ‘DELETED‘)
    FAILED_TIMEOUT_GUESTAGENT = ServiceStatus(0x18, ‘guestagent error‘,
                                              ‘ERROR‘)
    INSTANCE_READY = ServiceStatus(0x19, ‘instance ready‘, ‘BUILD‘)
    RESTART_REQUIRED = ServiceStatus(0x20, ‘restart required‘,
                                     ‘RESTART_REQUIRED‘)
