i'm putting together a RAID10 array for an office file server**, and i'm curious as to what happens after N months. let's say i build it using an existing 2TB drive and 3 new 1TB drives. clearly, the final RAID10 array will only be 2TB in total since it's dictated by the smallest drive in the array.
months later, i might have to replace some of the drives as they fail, and rebuild the array. let's assume i replace any dead 1TB drives with new 2TB drives. during that time, the array is still 2TB due to smallest drive. once THAT drive gets swapped out for a 2TB drive, what happens?
does my final array grow from 2TB to 4TB on its own without any special additional rebuild? or does it stay locked at 2TB until i reset it and copy files from a backup?
initial: 2+1+1+1 = 2
then: 2+2+1+1 = 2
then: 2+2+2+1 = 2
final: 2+2+2+2 = ??
