I have 5 9gb drives setup in a raid 5 config. I would like to dd a 6th. Although I cannot find a 9gb drive. Could I use say an 18.4gb drive without messing up the raid config.

Thanks for the help

Generally the answer is yes. You need to review the documentation for your specific RAID controller. Generally what will happen is that if the drive is larger than the other drives, it will be "coerced" to a size that matches the other drives. All extra space will be unusable.
