Creating MVS File Systems

After a volume set is created, creating a VxFS file system is the same as creating a file system on a raw device or volume. You must specify the volume set name as an argument to mkfs as shown in the following example:

After the file system is created, VxFS allocates space from the different volumes within the volume set. You can list the component volumes of the volume set using of the fsvoladm command:

To add a new volume, first add the volume to the volume set, then add it to the file system:

A volume must be empty before you can remove it from the file system. With the exception of volume additions and deletions, file system commands operate the same on volumes within a volume set.
