A two disk raid 5 is "degraded", and it will complain till you complete it.
Where have you go this idea?
Several sources. For instance: https://en.wikipedia.org/wiki/RAID#Standard_levels «RAID 5 RAID 5 consists of block-level striping with distributed parity. Unlike in RAID 4, parity information is distributed among the drives. It requires that all drives but one be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost. RAID 5 requires at least three disks.[11] RAID 5 is seriously affected by the general trends regarding array rebuild time and the chance of drive failure during rebuild.[22] Rebuilding an array requires reading all data from all disks, opening a chance for a second drive failure and the loss of entire array. In August 2012, Dell posted an advisory against the use of RAID 5 in any configuration on Dell EqualLogic arrays and RAID 50 with "Class 2 7200 RPM drives of 1 TB and higher capacity" for business-critical data.[23]» Notice the «RAID 5 requires at least three disks.» - -- Cheers / Saludos, Carlos E.
