Ongoing Migration of a File System
The following example describes how to migrate a file system between on an ongoing basis. Some
of the following steps require a backup of the file system to be created. To simplify the process, you
can create one backup before performing any of the steps instead of creating multiple backups as
you go.
▼ To perform an ongoing migration
1. Ensure that there are no files in the file system that will be inaccessible after migrating the data
due to large file size or user/group id platform differences:
# fscdstask validate OS mount_point
If such files exist, move the files to another file system or reduce the files’ sizes.
Note There is no output if no limits are exceeded.
2. Add to the OS_list file:
3. Enforce the limits:
# fscdstask limit enforce mount_point
This is the last of the preparation steps. When the file system is to be migrated, it must be
unmounted, and then the storage moved and mounted on the target system:
4. Unmount the file system:
# umount mount_point
