Command Description
General Commands:
status [<node>] Retrieve status of every node (default)
Retrieve status of a specified node
whereis <file-path> Retrieve an assigned object by a file path
Storage Operation:
detach <storage-node> Remove a storage node in a LeoFS' storage cluster
Current status: running OR stop
suspend <storage-node> Suspend a storage node for maintenance
This command does NOT detach a node from a LeoFS' storage cluster
While suspending, it rejects any requests
Current status: running
resume <storage-node> Resume a storage node for finished maintenance
Current status: suspended OR restarted
start Start LeoFS after distributing a RING from LeoFS Manager to LeoFS Storage and LeoFS Gateway
rebalance Commit detached and attached nodes to join a cluster
Rebalance objects in a cluster based on updated cluster topology
mq-stats <storage-node> See statuses of message queues used in a LeoStorage node
mq-suspend <storage-node> <mq-id> Suspend a process consuming a message queue
Active message queues only can be suspended
While suspending, no messages are consumed
mq-resume <storage-node> <mq-id> Resume a process consuming a message queue
Recover Commands:
recover-file <file-path> Recover an inconsistent object specified by a file-path
recover-node <storage-node> Recover all inconsistent objects in a specified node
recover-ring <storage-node> Recover RING, a routing table of a specified node
recover-cluster <cluster-id> Recover all inconsistent objects in a specified cluster in case of using the multi datacenter replication
Compaction Commands:
compact-start <node> <num-of-targets> [<number-of-compaction-procs>] Remove unnecessary objects from a specified node
num-of-targets: It controls a number of containers in parallel
num-of-compaction-procs: It controls a number of procs to execute the data compaction in parallel
compact-suspend <storage-node> Suspend a data compaction processing
compact-resume <storage-node> Resume a data compaction processing
compact-status <storage-node> See current compaction status
Compaction’s status: idle, running, suspend
diagnose-start <node> Diagnose data of a specified storage node
Disk Usage Commands:
du <storage-node> See current disk usages
du detail <storage-node> See current disk usages in detail
Gateway Operation:
purge-cache <file-path> Remove a cache from each LeoFS gateway
remove-gateway <gateway-node> Remove a specified LeoGateway node, which is already stopped
Manager Maintenance:
backup-mnesia <backup-filepath> Copy LeoFS’s Manager data to a filepath
restore-mnesia <backup-filepath> Restore LeoFS’s Manager data from a backup file
update-managers <manager-master> <manager-slave> Update LeoFS Manager nodes
Destribute a new LeoManager nodes to LeoStorage and LeoGateway
dump-ring <node> Dump RING, a routing table to a local disk
update-log-level gateway/storage-node> <log-level> Update log level of a specified node
log-level: debug, info, warn, error
update-consistency-level <write-quorum> <read-quorum> <delete-quorum> Update current consistency level of R-quorum, W-quorum and D-quorum
Watchdog Operation:
update-property <node> <property-name> <property-value> Update watchdog properties of a specifid node, which includes as below:
- watchdog.cpu_enabled <boolean>
- watchdog.cpu_raised_error_times <integer>
