Expanding a Silicon File System
A Silicon File System can be expanded at any time and without interruption of service if the
following conditions exist:
❑
There is sufficient available free space in its Storage Pool.
❑
The file system expansion will not cause the file system to exceed the maximum
allowable number of
chunks
in a file system.
❑
There are sufficient
chunks
available in the Storage Pool to support the desired
expansion.
There are two ways a Silicon File System can be expanded. One is manually, and the other is
automatically. File systems cannot be reduced in size.
To Manually Expand a Silicon File System
Manual expansion of Silicon File Systems is an operation supported through the Command Line
Interface. For detailed information on this process, run
man filesystem-expand
at the CLI.
To Automatically Expand A Silicon File System
The amount of space a file system occupies in a Storage Pool can be automatically increased
when needed. An overall size limit can also be set to control the amount of space it takes in a
pool. The change can be applied without removing the file system from service.

Reducing the Size of a Silicon File System
The size of a Silicon File System cannot be reduced. This is also the case with a Storage Pool.
Relocating a Silicon File System
Every Silicon File System must be associated with an EVS for it to be shared or exported,
making it available to network clients. The association between a file system and a particular
EVS is established when the file system is created. Over time, requirements for storage
