Creating and managing volumes
You can create and delete FlexVol volumes, change their basic attributes, and display information about how their space is being used.
- Creating a volume
You can create a volume and specify its junction point and other properties by using the volume create command. - Understanding SAN volumes
ONTAP provides three basic volume provisioning options: thick provisioning, thin provisioning, and semi-thick provisioning. Each option uses different ways to manage the volume space and the space requirements for ONTAP block sharing technologies. Understanding how the options work enables you to choose the best option for your environment. - Displaying file or inode usage
FlexVol volumes have a maximum number of files that they can contain. Knowing how many files are contained by your volumes helps you determine whether you need to increase the number of (public) inodes for your volumes to prevent them from hitting their maximum file limit. - Controlling and monitoring I/O performance to FlexVol volumes by using Storage QoS
You can control input/output (I/O) performance to FlexVol volumes by assigning volumes to Storage QoS policy groups. You might control I/O performance to ensure that workloads achieve specific performance objectives or to throttle a workload that negatively impacts other workloads. - Deleting a FlexVol volume
You can delete a FlexVol volume that is no longer required or if it contains corrupted data. - Deleting directories
Beginning in ONTAP 9.8, you can delete large directories with lower latencies. This improved method of directory delete can be implemented through a new REST API or using the ONTAP command line interface (CLI). - Commands for managing FlexVol volumes
There are specific commands for managing FlexVol volumes using the ONTAP CLI. - Commands for displaying space usage information
You use the storage aggregate and volume commands to see how space is being used in your aggregates and volumes and their Snapshot copies.
