NSS allows you to temporarily deactivate individual storage pools to fix volume problems instead of bringing down the server. However, when you deactivate a storage pool, users do not have access to any of the volumes in that pool. You cannot rebuild or verify an NSS volume independently of other volumes in the same pool. For more information, see Section 11.11, Verifying and Rebuilding NSS Pools and Volumes.
IMPORTANT:A pool rebuild does not restore the data itself. Instead, it restores consistency to the data structure itself after data corruption. Data is likely to be lost during a rebuld so rebuild pools only as a last resort.
