What happens if a disk fails in RAID 6?
If a third disk in a RAID 6 disk array fails, the array is marked as Failed and its data is not accessible. If a third disk in a RAID 6 disk array fails, you must replace the failed disks, then delete and recreate the disk array.
How many disk can fail in RAID 6?
RAID 6 uses two parity stripes, the practice of dividing data across the set of hard disks or SSDs, on each disk. It allows for two disk failures within the RAID set before any data is lost.
