Fix unstable chain

1 Owner & Isolation node

1.1 Confirm that the chain synchronization is normal

View the log of the chain with the following command:

sudo crust logs chain

If the best block reaches the highest block (the highest can be viewed on APPs, and the gap between finalized block and best block is less than 5 blocks, that indicates the chain is in normal condition. As shown below:

If there is an abnormality, please shovel the chain data. It is recommended to use the db of the normal Owner node for synchronization acceleration, or you can use the following command to download the synchronized Owner db for replacement:

wget https://gw.crustapps.net/ipfs/QmdyD9QqAF9FLWFk1dvKzFnoQ4LH1nU4BrGQUtWu5bC3Q5
sudo crust stop chain
sudo rm -rf /opt/crust/data/chain/chains/crust/db/
sudo tar -xvf QmdyD9QqAF9FLWFk1dvKzFnoQ4LH1nU4BrGQUtWu5bC3Q5 -C /opt/crust/data/chain/chains/crust/
sudo crust start chain

1.2 Become a Validator again

Before performing this step, please double check whether the node is synchronized to the highest block, and the gap between finalized and best is less than 5 blocks. As shown below:

If the synchronization is completed successfully, execute the validate operation in APPs to become a validator again

Note: If you delete the complete chain folder "/opt/crust/data/chain/chains", need to re-acquire and set the sessionkey, wait for the chain to synchronize normally, and execute the validate operation again
