So my experience with RAID is minimal. So I figured I’d come and ask here. We have a 16 drive RAID system that have 15 drives in RAID 5 with a hot spare left over. Recently one of the drives in the RAID was giving errors so I cloned it over to the hot spare and put a new drive in it’s spot. I made the new drive the hot spare as I was told. I was told to rebuild the array after putting in the new drive as a hot spare so I tried and wasn’t able to. So my question is do I need to rebuild it and if so why did it tell me I couldn’t. Thanks!
UPDATE: So I’ve come back up to work and looked at the RAID and it pulled in the hot spare into the raid and kicked out another drive.
My answer:
The rebuild is meant to occur when you begin using the existing hot spare in an array, not when you add a new hot spare. After all, it’s “spare” and should be unused until needed.
