152 Chapter 7 Solving SAN Problems
You’re Unable to Add LUNs to a Storage Pool
You can’t add a new LUN to an existing storage pool unless the LUN is at least as large
as the common LUN size for the pool. (The common LUN size is the same as the size of
the smallest LUN you added when you created the pool.) You can add a larger LUN, but
space beyond the common LUN size is not used.
Also, you can’t add a LUN to an existing storage pool if the storage pool is used to store
journal data or metadata. This applies to any storage pool set to be used for “Journaling
and metadata only” or “Any data.”
