• Change logs. These log files contain a history of the watched files and changes to those files during a single replication interval. There is a change log for each node. At the end of a replication interval, these logs are merged into one change log that specifies all of the files that are to be transferred to the destination cluster. (If a file already exists on the destination cluster, only the changes in the file will be transferred.) • Delete logs. These log files contain a history of the files that were deleted during a single interval. There is a delete log for each node. At the end of a replication interval, these logs are merged into one delete log that specifies all of the files that are to be deleted from the destination cluster. The log files are in a binary format and cannot be viewed with a text editor. Use the rpl_create_hr command as follows to convert the files into a readable format. rpl_create_hr [ ...] The following log files can be converted: • /replication/logs/ • /replication/logs/merge/change/rep_log. • /replication/logs/merge/delete/master_delete. • /replication/logs/merge/newdir/ • /replication/message/skip_log. Replication history file The rplmonitor program creates a history file containing a record of the nodes participating in replication and a record of the most recent replication intervals for each node. For each replication interval, the information in the file includes the IP addresses of the cluster nodes participating in replication and, for each replication interval, the interval switch times (when one interval ends and the next interval begins), the number of mounted directories that were replicated, and the number of acknowledgements from the worker threads performing the replication. The history file is located at /_adminfs/replication/messages/ rplclusterfile. The file is in a binary format and should not be edited directly. Use the following command to convert the file to a text format: # rplctldump [-o ] /_adminfs/replication/messages/ rplclusterfile The -o option specifies the name of the file that will contain the converted output. If this option is not specified, rplmonitor will generate a name for the output file. HP Scalable NAS File Serving Software administration guide 271
