Changing the storage pool assignment of a file
You can change the storage pool that a file is assigned to.
A root user can change the storage pool that a file is
assigned to by either:
- Running mmapplypolicy with an appropriate set of policy rules.
- Issuing the mmchattr -P command.
By default, both of these commands migrate data immediately
(this is the same as using the -I yes option
for these commands). If desired, you can delay migrating the data
by specifying the -I defer option for either
command. Using the defer option, the existing data does not get moved
to the new storage pool until either the mmrestripefs command
or the mmrestripefile command are executed.
