If your zFS file system runs out of space, you have several options to increase its size:

• You can grow the aggregate. For more information, see Growing a compatibility mode aggregate.
• If you cannot grow the aggregate (because, for example, there is no more room on the volume), you can add a volume to the aggregate. For more information, see Adding a volume to a compatibility mode aggregate.
• If you cannot grow the aggregate and you cannot add a volume (because, for example, you do not have any more volumes available), you can copy the aggregate into a larger VSAM linear data set. There are two ways to copy the data:
  • You can copy each file and directory of the zFS aggregate to a larger data set.
  • You can copy the physical blocks of the zFS aggregate to a larger data set.
