NAME gluster - Gluster Console Manager (command line interpreter) SYNOPSIS To run the program and display the gluster prompt: gluster To specify a command directly: gluster [COMMANDS] [OPTIONS] DESCRIPTION The Gluster Console Manager is a command line utility for elastic volume management. You can run the gluster command on any export server. The command enables administrators to perform cloud operations such as creating, expanding, shrinking, rebalancing, and migrating volumes without needing to schedule server downtime. COMMANDS Command Description Volume volume info [all | VOLNAME] Displays information about all volumes, or the specified volume. volume create NEW-VOLNAME [stripe COUNT] [replica COUNT] [transport tcp | rdma | tcp,rdma] NEW-BRICK ... Creates a new volume of the specified type using the specified bricks and transport type (the default transport type is tcp). volume delete VOLNAME Deletes the specified volume. volume start VOLNAME Starts the specified volume. volume stop VOLNAME [force] Stops the specified volume. volume rename VOLNAME NEW-VOLNAME Renames the specified volume. volume help Displays help for the volume command. Brick volume add-brick VOLNAME NEW-BRICK ... Adds the specified brick to the specified volume. volume replace-brick VOLNAME (BRICK NEW-BRICK) start | pause | abort | status Replaces the specified brick. volume remove-brick VOLNAME [(replica COUNT)|(stripe COUNT)] BRICK ... Removes the specified brick from the specified volume. Rebalance volume rebalance VOLNAME start Starts rebalancing the specified volume. volume rebalance VOLNAME stop Stops rebalancing the specified volume. volume rebalance VOLNAME status Displays the rebalance status of the specified volume. Log volume log filename VOLNAME [BRICK] DIRECTORY Sets the log directory for the corresponding volume/brick. volume log rotate VOLNAME [BRICK] Rotates the log file for corresponding volume/brick. volume log locate VOLNAME [BRICK] Locates the log file for corresponding volume/brick. Peer peer probe HOSTNAME Probes the specified peer. peer detach HOSTNAME Detaches the specified peer. peer status Displays the status of peers. peer help Displays help for the peer command. Geo-replication volume geo-replication MASTER SLAVE start Start geo-replication between the hosts specified by MASTER and SLAVE. You can specify a local master volume as :VOLNAME. You can specify a local slave volume as :VOLUME and a local slave directory as /DIRECTORY/SUB-DIRECTORY. You can specify a remote slave volume as DOMAIN::VOLNAME and a remote slave directory as DOMAIN:/DIRECTORY/SUB-DIRECTORY. volume geo-replication MASTER SLAVE stop Stop geo-replication between the hosts specified by MASTER and SLAVE. You can specify a local master volume as :VOLNAME and a local master directory as /DIRECTORY/SUB-DIRECTORY. You can specify a local slave volume as :VOLNAME and a local slave directory as /DIRECTORY/SUB-DIRECTORY. You can specify a remote slave volume as DOMAIN::VOLNAME and a remote slave directory as DOMAIN:/DIRECTORY/SUB-DIRECTORY. volume geo-replication MASTER SLAVE config [options] Configure geo-replication options between the hosts specified by MASTER and SLAVE. gluster-command COMMAND The path where the gluster command is installed. gluster-log-level LOGFILELEVEL The log level for gluster processes. log-file LOGFILE The path to the geo-replication log file. log-level LOGFILELEVEL The log level for geo-replication. remote-gsyncd COMMAND The path where the gsyncd binary is installed on the remote machine. ssh-command COMMAND The ssh command to use to connect to the remote machine (the default is ssh). rsync-command COMMAND The rsync command to use for synchronizing the files (the default is rsync). volume_id= UID The command to delete the existing master UID for the intermediate/slave node. timeout SECONDS The timeout period. sync-jobs N The number of simultaneous files/directories that can be synchronized. ignore-deletes If this option is set to 1, a file deleted on master will not trigger a delete operation on the slave. Hence, the slave will remain as a superset of the master and can be used to recover the master in case of crash and/or accidental delete. Other help Display the command options. quit Exit the gluster command line interface.
