26.2 Migration from a GFS Local File System

For file system migration, move files and directories from the GFS Local File System to another location such as a backup device or another file system. After creating the new GFS Shared File System, the files should be restored as shown below.

1. Check that this GFS Local File System is not in use.
2. Move all the files on the GFS Local File System to a backup device or another file system by executing tar(1), cpio(1) and sfxcpio(1).
3. Create the GFS Shared File System on a disk, as described in "21.2 Creation", "22.2 Flow from file system creation to mount/umount."
4. Restore the saved files to the newly created GFS Shared File System.

- The user regulation values for the quota function on the GFS Local File System need to be set.

- When the ACL function is used on a GFS Local File System, the ACL information can be moved with tar(1), cpio(1), sfxcpio(1) and sfxdump(1M).

- When the GFS Local File System extent property is set, the extent information can be moved with sfxcpio(1) or sfxdump(1M). When the data is moved with sfxcpio(1), restore it with sfccpio(1). When it is moved with sfxdump(1M), restore it with sfxrestore(1M).

- When moving files on a GFS Local File System to a GFS Shared File System with tar(1), cpio(1) and sfxcpio(1), the files are defragmented because the addition memory that would be required if the files were found to be fragmented during restoration. Use sfxdump(1M) and sfxrestore(1M) if you wish to perform backup and restoration with the fragmented state maintained.
