How Do I Do If Trust Relationships Between Nodes Are Abnormal?
If "ALM-12066 Inter-Node Mutual Trust Fails" is reported on Manager or there is no SSH trust relationship between nodes, rectify the fault by performing the following operations:
- Run the ssh-add -l command on both nodes of the trusted cluster to check whether there are identities.
- If no identities are displayed, run the ps -ef|grep ssh-agent command to find the ssh-agent process, kill the process, and wait for the process to automatically restart.
- Run the ssh-add -l command to check whether the identities have been added. If yes, manually run the ssh command to check whether the trust relationship is normal.
- If identities exist, check whether the authorized_keys file in the /home/omm/.ssh directory contains the information in the id_rsa.pub file in the /home/omm/.ssh of the peer node. If no, manually add the information about the peer node.
- Check whether the permissions on the files in /home/omm/.ssh directory are correct.
- Check the /var/log/Bigdata/nodeagent/scriptlog/ssh-agent-monitor.log file.
- If the home directory of user omm is deleted, contact MRS support personnel.
