Show Cluster Information
Get cluster information, including cluster name, address, number of volumes, number of nodes, and usage rate, etc.
cfs-cli cluster info
Show Cluster Usage
Get usage, status, etc. of metaNodes and dataNodes by region.
cfs-cli cluster stat
Freeze/Unfreeze Cluster
Freeze the cluster. After setting it to true, when the partition is full, the cluster will not automatically allocate new partitions.
cfs-cli cluster freeze [true/false]
Set Memory Threshold
Set the memory threshold for each MetaNode in the cluster. If the memory usage reaches this threshold, all the metaPartition will be readOnly. [float] should be a float number between 0 and 1.
cfs-cli cluster threshold [float]
Set Volume Deletion DelayTime
Set the volDeletionDelayTime configuration, measured in hours, which represents the number of hours after enabling delayed volume deletion when the volume will be permanently deleted. Prior to that, it will be marked for deletion and can be recovered. default is 48 hours.
cfs-cli cluster volDeletionDelayTime [VOLDELETIONDELAYTIME]
Cluster Configuration Setup
Set the configurations of the cluster.
cfs-cli cluster set [flags]
Flags:
--autoRepairRate string DataNode auto repair rate
--batchCount string MetaNode delete batch count
--deleteWorkerSleepMs string MetaNode delete worker sleep time with millisecond. if 0 for no sleep
-h, --help help for set
--loadFactor string Load Factor
--markDeleteRate string DataNode batch mark delete limit rate. if 0 for no infinity limit
--maxDpCntLimit string Maximum number of dp on each datanode, default 3000, 0 represents setting to default
