show space grain_alloc
Parameters
Parameter |
Description |
Value |
|---|---|---|
| file_system_id=? | File system ID. | To obtain the value, run the "show file_system general" command. |
| controller=? | Controller ID. | The value is in the format of "XA" or "XB" or "XC" or "XD", where the "X" is an integer ranging from 0 to 3, for example: "0A", "1C". |
Usage Guidelines
Before running this command, check whether the working controller ID of the file system is correct.
Example
Query information about distributive tree.
