The purpose here is about adding the 'noatime' property in /etc/fstab. We're running CentOS5.
On both servers A and B, we called a maintenance window with our users and stopped MySQL and Apache services.
On Server A, my client properly installed /var/lib/mysql and /home into separate partitions when I checked /etc/fstab. I was able to set the noatime property and remount the volumes, and when I checked with "mount -l" they showed the noatime property. Indeed, the server performance was much snappier when we fired up MySQL and Apache and told the users to get back on.
On Server B, however, my client just put everything on /. Is there an easy way at command line to break up /home and /var/lib/mysql from / so that we can apply noatime?
I'm just wanting to avoid having to do a complete server OS reinstall and then restoring cPanel accounts again.
