In the RHGS v3.2 Admin Guide I read "Red Hat Gluster Storage includes tuned profiles tailored for its workloads.".
However, these profiles (rhgs-random-io and rhgs-sequential-io) seem not to be present on the Gluster nodes in /etc/tuned (check with ls).
So, setting the profile fails:
$ tuned-adm profile rhgs-random-io
Requested profile 'rhgs-random-io' doesn't exist.
We are using a layered install (instead of ISO) on RHEL7.3.
Is that the reason? Or how are these profiles installed?
