I'm trying to move to CentOS 7. One of my concerns is how to make the changes to grub that supports booting from either of the disk partitions that make up /dev/md0 (/dev/sda1 and /dev/sdb1) or whatever it would be under CentOS 7. Is there some document or tutorial available on making the move from CentOS 6 to CentOS 7? -- Eugene Poole Woodstock, Georgia
