How to replace failing Disk 1?
Our small office currently runs about a 3 year old ReadyNAS NV+ with two Western Digital WDC WD5001ABYS drives. It is set up in a Raid 1 configuration. Got a smart error about 2 weeks ago and another ...
NV+ supports hot swap.
Boot the array and either force a rsync view the front view or just yank #1 (paper click in earlier models is necessary) and screw in a new drive and push it home. The sync should happen automatically...
The critical thing is to not do anything major with the machine until the swap is completed. If any of the other 3 drives fail, you will loose data.
I recall reading a study by google 2% chance for a double failure in raid array (2 failling at once) but I feel like it jumps to 9 if you let the array continue to run on just 3.
