3.18.22 Kernel RPM Contribution to CentOS
by gayathri.madda＠wipro.com 19 Jan '16

19 Jan '16

Hi Team, As there was no official Linux kernel RPM (version 3.18.22) for CentOS 7 in any of their distribution versions, we have customized spec file for creating 3.18.22 kernel RPM for CentOS-7 Minimal version by taking 3.18.12 kernel spec file STEPS for Generating Kernel RPM 1. Downloaded the latest 3.18.22 kernel source code "linux-3.18.22.tar.gz<https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.22.tar.gz>" from https://www.kernel.org/pub/linux/kernel/v3.x/ 2. Customized the 3.18.12 kernel spec file w.r.t 3.18.22 kernel SPEC and created RPM for CentOS 7 Minimal Version Regards, Gayathri The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.

Use of PTPd on CentOS 6
by Claudio Scordino 19 Jan '16

19 Jan '16

I need to create a reliable and accurate synchronization between two CentOS 6 machines connected through a direct Ethernet connection. I've seen that on Linux several implementation of the IEEE 1588 Precision Time Protocol (PTP) <https://en.wikipedia.org/wiki/Precision_Time_Protocol> exist: - PTPd <http://ptpd.sourceforge.net>: - Apparently, this is the original implentation - Apparently, it is still maintained <http://www.github.com/ptpd/ptpd> - PTPd2 <http://ptpd2.sourceforge.net>: - A new version meant to supersede the previous implementation - Apparently unmaintained - For CentOS 6, available only in the EPEL repositories - PTPv2d <http://code.google.com/p/ptpv2d>: - A further implementation - Unmaintained as well - linuxptp <http://linuxptp.sourceforge.net>: - A specific implementation for Linux - Maintained - Available on the CentOS repositories - Suggested by the RedHat documentation for both RedHat 6 <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht…> and RedHat 7 <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/ht…> My questions follow: - Why does the RedHat documentation suggest the use of linuxptp <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht…> for RedHat 6 (based on Linux kernel 2.6) despite the linuxptp documentation says that a Linux kernel version 3.0 or newer is needed <http://linuxptp.sourceforge.net/> ? - Which are differences between PTPd2 and Linuxptp in terms of reliability and timing accuracy ? - Which one should I prefer on CentOS 6 and on CentOS 7, respectively ? - Why either PTPd2 and Linuxptp do not synchronize immediately and often need me to start/stop the service several times or manually change system time through date to make the machine synchronize ? Many thanks for any hint.

Introduction for SCLo SIG and PHP package - remi
by Remi Collet 19 Jan '16

19 Jan '16

Howdy, CentOS account (FAS) : remi PHP packages maintainer in various places. Goal: I'd like to build various additional packages for the various PHP SCL which are not available in upstream RHSCL. Those packages will use "sclo-php5#" prefix, but are really part of the (rh-)php5# collection, different prefix used to avoid user confusion. Notice: most of those, are already built in 'morephp5#' community repository. So I need CBS access to be able to build them. Remi.

Yes, in case someone would like to include different set of packages or deliver different version, then it effectively become a new SCL, that needs to be treated that way. Honza

CentOS ppc64le hypervisor support
by James Nash 15 Jan '16

15 Jan '16

Is there a list of "supported" methods for deployment of CentOS 7.2 on Power8? I know folks with VMs behind VIO servers with PowerVM. I understand VMs under PowerKVM with OPAL are also supported. Any ideas on bare metal CentOS under OPAL, Power8 with either latest firmware levels (FW840 or OP810)?

Wiki Correction?
by Brian (bex) Exelbierd 13 Jan '16

13 Jan '16

On this page: https://wiki.centos.org/Cloud/AWS <https://wiki.centos.org/Cloud/AWS> Should this line, "All images have root logins which are enabled only via a ssh key." actually reference the fact that login is accomplished via the userid "centos" ? I'll fix it, if so. If not, then it must be from my use case. regards, bex -- Brian (bex) Exelbierd P: +1-919-414-8915 <tel:+1-919-414-8915> (US) | P: +420 606 055 877 <tel:+420%20606%20055%20877> (CZ) | E:bex@pobox.com <mailto:bex@pobox.com> (preferred) IM: Google: bcexelbi(a)gmail.com <mailto:bcexelbi@gmail.com> | QQ: 1927508627 <tel:1927508627> | Skype: bcexelbi | MSN: bex(a)pobox.com <mailto:bex@pobox.com> | WeChat: bcexelbi

Ceph/Storage SIG

Hi, In order to be truly independent from EPEL, the Cloud SIG/OpenStack is looking to consume Ceph from Storage SIG repo. Seems that the only builds are from oVirt and testing build targets, so I'd like to confirm what are the plans to deliver Ceph if there are any? Regards,
