Last modified: 2017-11-17 00:29:54 EST
Section Number and Name:
Describe the issue:
New tuned profiles have been added for RHGS on RHEL-7. They need to be documented in the admin guide
Bug 1242454 - RHGS tuned profiles incompatible with RHEL7 tuned
Bug 1243725 - Do not install RHEL-6 tuned profiles in RHEL-7 based RHGS
Suggestions for improvement:
Section 11.2.7 Performance tuning option in Red Hat Gluster Storage
[note that the current text applies to RHEL-6 tuned profiles]
[add the following at the end of the sub-section]
On RHEL 7, there are two tuned profiles available,
rhgs-sequential-io and rhgs-random-io. Choose between
these profiles based on your workload, as recommended in the
Workload | Profile Name
large-file, sequential I/O workloads | rhgs-sequential-io
small-file workloads | rhgs-random-io
random I/O workloads | rhgs-random-io
Activate the tuned profile using the command:
tuned-adm profile <profile-name>
tuned-adm profile rhgs-sequential-io
Section 11.4.1 Virtual Memory Parameters
[Add the following note immediately after the table 11.1]
Note: The RHEL-7 tuned profiles, rhgs-sequential-io and
rhgs-random-io, set the virtual memory parameter values as given
in table 11.1 The rest of this sub-section is necessary only on RHEL-6.
11.5. Small File Performance Enhancements
[change the note in para 2. to the following]
Note: On RHEL 7, for a small-file workload, activate the rhgs-random-io
tuned profile. On RHEL 6, for a small-file workload, see the
<previous section> for instructions on configuring virtual memory parameter values.
11.6 Number of Clients
[Note that this applies for RHEL-6 only]
The details are updated as suggested. Do share your review comments if any.
There are some spelling errors in the addition to 11.6 that needs fixing.
Rest seems fine. All changes are in the right place.
Also checked the doc as available in doclink provided in comment3.
As Manoj pointed out, the note under section 11.6 requires spelling correction.
Also it calls RHGS 3.1 as 'Red Hat Gluster 3.1', which could be termed as 'Red Hat Gluster Storage 3.1'
The changes are incorporated.
Please check the link after an hour to view the changes.
Verified with the doc-link available in comment3.
It looks good.
Marking this bug as VERIFIED
