23.6.1 Acquiring file system information

Information about a file system, including the use of disk blocks, the state of free disk blocks, and the number of files, can be acquired using df_sfcfs(1M).

If a file system consists of multiple partitions, df_sfcfs(1M) will display information about each partition.

The following information is displayed for a meta-data partition:

• Use of i-nodes (number of i-nodes, number of free i-nodes)
• Free extent status (maximum number of leafs and amount used)
• Use of V-data (maximum number of V-data blocks and number used)
• unused area (size of the unassigned area)

The following information items are displayed for a file data partition:

• Total number of blocks and number of free blocks

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

In the following example, df_sfcfs(1M) is used to display how a file system is being used.
