That makes more sense. Have you measured the write load on the disks from just the hypervisor processes. I have included a screen shot from mine, and the load is very low.... in the Kilobytes/sec

I am not sure of the implications of changing these parameters, and I do not see an perceivable benefits from doing so.

What is the purpose in putting these directives in for the hypervisor?

I have small node where system and data domains located on the same RAID.
Data domains are on separate partitions.
These options allow minimise disk access activity.

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.
