I am having trouble with an install of new hard drives into a clone machine running ver 8.3.2. The install was prompted by a bad HD that was corrupting files. The old drives that were were WD Blue series 1 TB were configured Raid Stripe.. The new drives are WD Red series 2 TB which I was trying to configure Raid Mirror. I am booting from a USB Stick. The problem I am having is that when I go to Create a Volume I get a message that an error occurred. There is no error number, just that an error has occurred. In my experimenting for a solution I have tried both Raid Mirror and Raid Stripe and no Raid. In each case I get the same error. The things I have done are: resetting the HD's in the raid bios when a change in the Raid config was being attempted, I have run fsck several times and errors have been found and fixed. The computer is confgured as follows: an ASUS Motherboard with 8GB RAM, a bios that supports raid technology, and the WD Red HD's are new out of the box. In addition to the 2 raid HD's there is a third 1 TB drive is configured to stand alone. This machine is used as a network storage device at a Lutheran elementary school with about 50 computers accessing the storage device. I plan to check the MB mfr for bios updates. Is the third HD causing problems ? Should I be upgrading to a more recent version of freenas? Are there any other ideas anyone has to share?
