I have (what is _now_) a cold spare drive that was previously used as part of a test raid group a long time ago...and that raid group no longer exists, so there is no actual data on this drive at all, aside from the old / stale RAID config data
I wish to use this drive again to rebuild a group that failed over the weekend, but I can't figure out how to wipe the previous raid config data from the drive so that it can actually be used for the rebuild.
Can someone please help me with this? I can't believe this is so hard, lol.
There has to be a one line CLI command to wipe the old RAID config, you'd think anyway?
