Apple Xsan 1.1 - Manual (Page 41)

Chapter 2 Setting Up a Storage Area Network 41
Step 10: Add Storage Pools to the Volumes
1 Select a volume in the list and click the New Storage Pool button (next to the list).
2 In the storage pool dialog, provide the following information.
Storage Pool Name: Type a name for the storage pool. If the OK button is disabled
after you type a name, the name is reserved. For a list of reserved names, see “You’re
Unable to Add a Storage Pool” on page 98.
Use for: Choose the type of data to store in the storage pool. Journal data is used by
the controller to ensure the integrity of files in the volume. Metadata is file system
information used by the controller. Journal data and metadata are always stored at
least on the first storage pool in a volume. If this is not the first storage pool in the
volume, you can choose “User data only.” To allow only files saved in a folder that has
an affinity for this storage pool, enable “Only data with affinity.”
Important: If you’re using a version of Xsan earlier than 1.1, be sure to store metadata
and journal data only on the first or the first and second storage pools in the volume.
