23.3.4 File Data Allocation Attribute Information

You can specify the allocation of specific file data from specific file data partitions. This is effective when you want to specify disk devices in a unit of directory in a file system composed of several file data partitions.

Use sfcsetvolume(1) to set file data allocation information. When file data allocation attribute information is set for a directory, that allocation information is automatically reflected for the files and directories created under the directory.

There are forced and suggested specifications in file data allocation attribute information setup. In forced specification, an error (ENOSPC) occurs when there's insufficient space on a file data partition that is specified when new data allocation is performed, even if the free space exists in other file data partitions. In the suggested specification, data allocation is done from other file data partitions when there's insufficient area in a specified file data partition.

For details on sfcsetvolume(1), see Appendix F.3.8, "sfcsetvolume(1)."
