Increasing File System Capacity

Increase a File Storage with Lustre file system's capacity.

File system capacity can be increased by specific increments. If the file system's capacity is at least 31.2 TB and less than or equal to 124.8 TB, it must be increased in 10.4 TB steps. If the file system's capacity is 124.8 TB or greater, it must be increased in increments of 41.6 TB.

You can't decrease the capacity of a file system.

Note

File system performance might be impacted for a few hours after an increase in capacity while existing file system data is rebalanced.
    1. On the Lustre file systems list page, find the file system that you want to work with. If you need help finding the list page, see Listing File Systems.
    2. From the Actions menu (Actions Menu) for the file system, select Increase capacity.
    3. In the Increase capacity panel, select a File system capacity value.
    4. Select Update.

  • Use the oci lfs lustre-file-system update command and the --capacity-in-gbs parameter to update a file system's capacity:

    oci lfs lustre-file-system update --capacity-in-gbs <capacity>

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the UpdateLustreFileSystem operation with the capacityInGBs attribute to update a file system's capacity.
