WD Red 3TB high RawReadErrorRate
Good day, Using a ReadyNAS Duo v2 I have almost reached my 3TB capacity in X-RAID2 mode. I was looking to expand, and upon checking the SMART status of the two discs, I have found, what I believe to...
Unfortunately you need to start fresh - the older NAS have no ability to switch between flexraid and xraid. OS6 does (with some limitations), of course you can only run 5.x.
My advice is to start with just the new disk installed in slot 1, and choose flexraid/jbod. After that setup completes, hot-insert the old disk in slot 2. There are two reasons
(a) if the initial setup fails for some reason, you still can fall back to your old setup by reinstalling the old disk in slot 1 with the NAS off.
(b) It makes it a little more difficult to accidentally end up in RAID1 (or RAID0)
