Maintaining the list of target operating systems
When a file system is migrated on an ongoing basis between multiple systems,
the types of operating systems that are involved in these migrations are maintained
in a target_list file. Knowing what these targets are allows VxFS to determine
file system limits that are appropriate to all of these targets. The file system limits
that are enforced are file size, user ID, and group ID. The contents of the
target_list file are manipulated by using the fscdsadm command.
Adding an entry to the list of target operating systems
To add an entry to the list of target operating systems
■ Type the following command:
# fscdsadm -o add -t target mount_point
See “Specifying the migration target” on page 487.
Removing an entry from the list of target operating systems
To remove an entry from the list of target operating systems
■ Type the following command:
# fscdsadm -o remove -t target mount_point
See “Specifying the migration target” on page 487.
Removing all entries from the list of target operating systems
To remove all entries from the list of target operating systems
■ Type the following command:
# fscdsadm -o none mount_point
Displaying the list of target operating systems
To display a list of all target operating systems
■ Type the following command:
# fscdsadm -o list mount_point
Enforcing the established CDS limits on a file system
By default, CDS ignores the limits that are implied by the operating system targets
that are listed in the target_list file.
