12.6. Geo-replication Logs

The following log files are used for a geo-replication session:

Master-log-file - log file for the process that monitors the master volume.
Slave-log-file - log file for process that initiates changes on a slave.
Master-gluster-log-file - log file for the maintenance mount point that the geo-replication module uses to monitor the master volume.
Slave-gluster-log-file - If the slave is a Red Hat Gluster Storage Volume, this log file is the slave's counterpart of Master-gluster-log-file.

To view the Master-log-file for geo-replication, use the following command:

# gluster volume geo-replication MASTER_VOL SLAVE_HOST::SLAVE_VOL config log-file

For example:

# gluster volume geo-replication Volume1 example.com::slave-vol config log-file

To view the log file for geo-replication on a slave, use the following procedure. glusterd must be running on slave machine.

On the master, run the following command to display the session-owner details:

# gluster volume geo-replication MASTER_VOL SLAVE_HOST::SLAVE_VOL config session-owner

For example:

# gluster volume geo-replication Volume1 example.com::slave-vol config session-owner 5f6e5200-756f-11e0-a1f0-0800200c9a66

On the slave, run the following command with the session-owner value from the previous step:

# gluster volume geo-replication SLAVE_VOL config log-file /var/log/gluster/SESSION_OWNER:remote-mirror.log

For example:

# gluster volume geo-replication slave-vol config log-file /var/log/gluster/5f6e5200-756f-11e0-a1f0-0800200c9a66:remote-mirror.log
