Cause: Because the usvr-211 was obtained through the vmware clone replication usvr-210, the two devices are exactly the same.

Some people say that because the uuid of the two machines is different, the uuid must be regenerated. The uuid file is installed in/var/lib/heartbeat by default. uninstallation is not deleted. If you do not delete it manually, the original uuid file will still be used for reinstallation.

So it is OK to delete it and reinstall it.
