The dual management node database is not synchronized

[nexus]

Problem description:
The dual management node database is not synchronized

Problem cause analysis:
After the management node runs for a period of time, the primary and standby database data may be inconsistent due to various problems.

Problem handling process:

1. Use the zsha2 command to check the database synchronization status, zsha2 db-status
2. Execute zsha2 stop-node on the two management nodes
3. Execute zsha2 db-sync -p [database password] -top on the vip to see the data size of each table
4. On the vip, depending on the situation, execute zsha2 db-sync -p [database password] -k (skip the backup of the standby database)
5. After completion, check that it is correct (execute zsha2 db-status) and restart the dual management node.
