Explanation

With two hard drives failed on a RAID 5 array, the server will not be fully operational until the data is restored from a backup. RAID 5 arrays are designed to tolerate a single drive failure, but if a second drive fails during the resynchronization process, the array will be unable to rebuild and the data will be lost.
