10.3.1 Acquiring file system information

Information about a file system, including the usage status of disk blocks, the state of free disk blocks, and the number of files, can be acquired using sfcdf(8).

sfcdf(8) will display information about each area.

• Use of i-nodes (number of i-nodes, number of free i-nodes)
• Free extent status (maximum and unused leaves)
• V-data usage status(maximum and unused V-data blocks)

The following information items is displayed for a file data area:

• Total number of blocks and number of free blocks

Only the number of assigned blocks is displayed for an update log area.

The following example shows how to display the usage status of a file system using df(1) and sfcdf(8).
