The consistency check on a RAID1 system simply compares the contents of the two mirrored partner disks, which normally should be identical (well, it's a mirror...).
Since one cannot determine beforehand whether the RAID inconsistency exists in a yet unused area of the disks, the best option is to install new, from scratch.
Should you declare the data you read from the disks right now to be ok, you could set one of the disks to failed, then perform a rebuild. This will copy all data from the remaining disk to the 'failed' one. After that process, you should start another concistency check. If this fails again, then there's probably something wrong with the hardware.
Please note that you should not start any OS in this process sequence!
