Capacity Expansion

Scenarios

You can expand the capacity of a file system if it is insufficient.

Notes and Constraints

SFS Turbo file systems support online capacity expansion. During an expansion, mounting the file system may fail. This is because the connection used for mounting may experience an I/O delay about 30 seconds (max. 3 minutes). You are advised to expand capacity during off-peak hours. Note that only In-use file systems can be expanded.

The capacity of an SFS Turbo file system cannot be reduced. You can buy a new file system with a smaller capacity and migrate your data to the new file system.

Expanding the Capacity of a Yearly/Monthly SFS Turbo File System

1. Log in to the SFS Turbo console.
2. In the file system list, locate the SFS Turbo file system you want to expand capacity and click Expand Capacity in the Operation column to open the Expand Capacity page.

   Table 1 Capacity expansion parameters

   Parameter	Description
   Current Capacity	Current storage capacity of the file system
   New Capacity	New storage capacity of the file system Constraints: For a Standard–Enhanced (Discontinued), Standard, Performance–Enhanced (Discontinued), or Performance file system, the expansion increment is 100 GB. A Standard or Performance file system can be expanded to up to 32 TB, and a Standard-Enhanced or Performance-Enhanced file system can be expanded to up to 320 TB. For a 20 MB/s/TiB, 40 MB/s/TiB, 125 MB/s/TiB, 250 MB/s/TiB, 500 MB/s/TiB, or 1,000 MB/s/TiB file system, the expansion increment is 1.2 TB, and a file system can be expanded to up to 1 PB.

3. Enter a new capacity based on service requirements and then click Next.
4. Confirm the resource information and click Submit.
5. Complete the payment as instructed and return to the file system list. Click the name of the expanded file system and check that the capacity has been expanded.
