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.
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.
