Description Jan Ščotka 2011-05-04 10:12:35 UTC

In section tuned, there should be mentioned arch specific variants (for s390x) isn't able to start tuned

In section tuned-adm I didn't find description of enterprise-storage profile.
What I expected that is more important.
And also spindown-disk profile, which can be harmfull for discs.

in 3.11. Optimizations in User Space
is still written Initscript audit, is BlueZ as example of improvements, but BlueZ is only one what is iproved :-)

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

We will not be releasing an update to the Power Management Guide in the 6.2 timeframe; moving to 6.3.

Hi Jan Vcelak,

I've tried to locate descriptions of the enterprise-storage and spindown-disk profiles in order to resolve this bug, but have not had much success.

I have assembled the following description of enterprise-storage from what little I could find:

"A profile that tunes large-scale storage performance by enhancing the performance of the CFQ I/O scheduler."

I have not been able to find anything for spindown-disk.

I need descriptions similar to those on the following page:

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Power_Management_Guide/tuned-adm.html

Are you able to comment on or provide an alternative to my description of enterprise-storage above, and either link me to or provide a description of spindown-disk?

Thanks for your time.
