Dear All:
I have a question. When I have a large cluster, maybe more than 10PB
data, if a file have 3 copies and each disk have 1TB capacity, So we need about
30,000 disks. All disks are very cheap and are easily damaged. We must repair
a 1TB disk in 30 mins。As far as I know，in gluster architecture，all
data in the damaged disk will be repaired to the new disk which is used to replace
the damaged disk. As a result of the writing speed of disk, when we repair 1TB
disk in gluster, we need more than 5 hours. Can we do it in 30 mins?
