Capacity Expansion

Scenarios

You can expand the capacity of a file system when needed.

Constraints

SFS Turbo file systems can only have their capacities expanded, not reduced. And only in-use file systems can be expanded.

Procedure

1. Log in to the SFS console.
2. In the file system list, click Expand Capacity in the row of the desired file system. A dialog box is displayed.
3. Enter a new capacity for the file system based on service requirements, and click OK. Table 1 describes the parameters.

   Table 1 Parameter description

   Parameter	Description
   Current Capacity	Current storage capacity of the file system
   New Capacity	Target storage capacity of the file system after the expansion is complete Value constraints: For a Standard, Standard-Enhanced, Performance, or Performance-Enhanced file system, the minimum 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, or 250 MB/s/TiB file system, the expansion increment is 1.2 TB, and the increment must be an integer multiple of 1.2 TB. The new capacity can be no more than 1 PB.

4. Enter a new maximum capacity of the file system based on service requirements, and click OK. Table 2 describes the parameters.

   Table 2 Capacity expansion parameters

   Parameter	Description
   Used Capacity (GB)	Used capacity of the current file system
   Maximum Capacity (GB)	Maximum capacity of the current file system
   New Maximum Capacity (GB)	Target maximum capacity of the file system after expanding The value ranges from 1 GB to 512,000 GB.

5. In the displayed dialog box, confirm the information and click OK.
6. In the file system list, check the capacity information after resizing.
