I am trying to calculate how long the rebulid time will be on my clusters array.
I am expanding the array by upgrading the disks from 176 gb to 300gb drives
the drives are 10k rpm with 64 kb stipe size.
The array has 7 drives and is 683 gb in size and 95% full
The Raid controller has 128mb Ram cache
Current rebuild priority low.
Please let me know your predictions (I will do this out of hours with low disk IO)
