I recently had a failing disk replaced in my colo server. The server is running Centos 7.3.
After the replacement, I was following these instructions to rebuild the RAID array that the disk was part of.

Everything went fine until I reached the final section ("Grub Setup"). This section talks about running a command line program called "grub" to change the Grub configuration. And that program doesn't seem to be installed on this server.
grub2 install /dev/sda grub2 install /dev/sdb
should do it, assuming the two actual physical disks are seen as /dev/sda and /dev/sdb
Thanks. That's what my independent research was showing me too.
I assume it's already installed to /dev/sda (as it was sdb which was recently replaced and the system is rebooting quite happily). Is there a command that shows which disks already have Grub2 installed?
