Removing RAID MetaData from disks when reusing
Nice post about removing the RAID metadata from a disk that won’t allow you to partition after reuse. I ran into this problem when trying to reuse disks from an older LSI/PERC raid configuration. CentOS 7.3 and RedHat just would not detect them. Running the below command in console of the installer removed the metadata so that I could reuse them. Thanks Randy!
