One-Time Migration of a File System
The following example describes a one-time migration of data from the . 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 a one-time migration
1. If the underlying Volume Manager storage is not contained in a CDS disk group, it must first
be upgraded to be a CDS disk group, and all other physical considerations related to migrating
the storage physically between systems must first be addressed as described in “Setting up
Your S y s tem” on page 11.
2. If the file system is using a disk layout version prior to 6, upgrade the file system to Version 6.
See the Storage Foundation Installation Guide for information on upgrading the file system to
disk layout Version 6.
3. 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.
4. Unmount the file system:
# umount mount_point
5. Use the fscdsconv command to convert the file system to the opposite endian, if required.
See “Converting a File System” on page 43.
6. Make the physical storage and Volume Manager logical storage accessible on the Linux system
by exporting the disk group from the source system and importing the disk group on the target
system after resolving any other physical storage attachment issues. See “Maintaining Your
System” on page 21 for more information.
