Both are no brainer to activate (noatime is a superset of nodiratime, see https://lwn.net/Articles/244941/) for every mount point, unless you really know why you need exact atime. If you want to be super-safe, use relatime. You will get not-exact but usable atime, to know if a file was acceded after write.

Hi !
Is it safe to turn on these options (noatime, nodiratime) in oVirt node fstab for these mount points? /home / /tmp /var /var/log /var/log/audit
Node 4.2 installed on CentOS, not with node DVD.
Thanks.
