I am wondering whether the raid rebuild process will impact the system performance significantly or not. Will the server be able to respond with a reasonable delay during the rebuild process?
Another question came to my mind. Is there any way we can give priority to the disk rebuild process? For example, can we limit the rate at which the data is read/written? Of course, this may be risky because we may have another failure during the rebuild. Let us focus on the performance aspect and ignore this risk!
I am talking about Linux raid mdadm.
