OR: • Use the ssh-keygen command to create the custom key pair. Then run the rplkeys -i command to import the key pair into the mxds datastore and publish it for replication use. The rplkeys -c and -i commands attempt to publish the key on the destination cluster. If the command is not successful (for example, because of ssh connection issues), you can use rplkeys -d to install the key on the destination cluster after the issues are fixed. Hard link behavior Because of the way that replication handles file change events, there is some odd behavior if multiple hard links to a single file are created in the same directory during a single interval. Each link will be given the same ID, and therefore only one of the objects will be included in the master replication log. This means that only that object will be replicated to the destination. (The hardlink instance that will be replicated is the last one to be modified on the node with the lexically highest IP address.) All of the user data will be on the destination, but the file structure will look different (it will be missing some hard links to the file). Later changes to these links will cause them to show up on the destination, as will any event that causes a sub-tree containing the links to be walked. Troubleshooting The following information may be useful for resolving replication issues. Replication files The following logs and files may be helpful when troubleshooting replication issues. Replication logs The replication log files created by rplwatch are located in the /_adminfs filesystem under the directory /replication/logs. The following types of logs are created: • Path logs. These log files contain the inodes and absolute paths of the directories included in the replica set. Replication uses this information internally to find the absolute paths for modified files in the directories. 270 Configure and manage replication
