Oops. It's probably a fairly close approximation to just mkfs.btrfs -f (or xfs) the entire block device for the SSD. If the kernel sees it as non-rotational, it'll issue a whole device trim first, then write out scant amount of metadata (btrfs writes out a tiny amount of metadata at mkfs time, xfs a bit more, ext4 a lot and then even more after mounting). For most people this is probably a lot easier than the multistep process using hdparm and secure erase. -- Chris Murphy _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
