B.1.2 df_sfxfs(1M) - Reports the free disk area of the GFS Local File System

[SYNOPSIS]

df -F sfxfs [ generic_options ] [ -o specific_options ] [ directory | special ]

[DESCRIPTION]

The df command displays the number of free disk blocks and of free i-nodes within the GFS Local File System. Note that the total area that is reported as being used or being ready for use is smaller than the actual area for the entire file system. This is because the system reserves a certain part of the file system area that is to be used for processing purposes of the file system allocation routine. This reserved area is generally 10% of the entire available area, but this size can be adjusted by sfxtune(1M). If the entire file system area is used with the exception of the reserved area, only the superuser can allocate the data blocks of new and existing files. If excessive space is allocated for the file system area in this way, the df reports that the file system area is used by more than 100%.

The special file or mounting point name can be specified. If it is omitted, information on each of the mounted file systems is displayed.

When a file system is configured with two or more partitions by the multi-partition function, specify the special file name with the path name of the representative partition.

When the GFS Local File System is configured with two or more partitions, information on each partition can be displayed.

• The following information is displayed for each meta partition:
  • i-node usage status (total number of i-nodes and number of free i-nodes)
  • Free extent status (total number of leaf and number of free leaf)
  • V data usage status (total number of blocks and number of free blocks)

• The following information is displayed for each data partition:
  • Free space in the data area

• The following information is displayed for each log partition:
  • Update log area size

The option generic_options is supported by the generic df command.

See the description of df(1M) options.
