recovery. Also explain why your system will operate correctly even if a
crash occurs in the middle of reconstruction.
10. Suppose you are willing to sacrice no more than 1% of a disk's bandwidth
to scrubbing. What is maximum frequency at which you could scrub a
1 TB disk with 100 MB/s bandwidth?
11. Suppose a 3 TB disk in a mirrored RAID system crashes. Assuming the
disks used in the system can sustain 100MB/s sequential bandwidth, what
is the minimum mean time to repair that can be achieved? Why might a
system be configured to perform recovery slower than this?
