Why are Spacewalk packages removed from CentOS?
by Luc de Louw 18 May '10

18 May '10

Dear all, After filing a bug (http://bugs.centos.org/view.php?id=4315) Karan made me aware of a discussion held in January 2010. There was no conclusion, no decision. The origin was from Miroslav he was requesting to include rhnlib and friends as I made is on the bug report, and I totally agree with him. Let me pick up the pros and cons discussed in January: Quoting Miroslav @ http://lists.centos.org/pipermail/centos-devel/2010-January/005319.html <quote> Partialy true. Recent upstream version will not hit accidentaly rhn.redhat.com That version included in RHEL will do that by default. But these change: https://fedorahosted.org/spacewalk/changeset/cd925d940357d145c7106c1c3ed6ed… is only one which are required to prevent from accidental check of rhn.redhat.com So my recomendation is: take this patch and apply it on current rhel5 package and include all of them in CentOS. </quote> As I stated, I agree with Miroslav, the only thing we need to care is not to bother people with "click-trough-installations" with "install-numbers" and stuff (This is in anaconda, right?) Lets have a look at http://lists.centos.org/pipermail/centos-devel/2010-January/005321.html Quoting Marcus: <quote> Spacewalk development is much faster which may lead into missing features as they are not yet implemented in the version that is meant to be used with rhn. </quote> From my point of view this does not matter that much.I was able to register a RHEL 5.4 to a spacewalk server (0.8? Dont remember, it was just for the sake, not for production). Since spacewalk is the upstream of the RHN satellite, Red Hat will be careful to break API compatibility between rhn-client and RHN Satellite/Spacewalk. Recently I replaced a RHN Sat 5.0 with 5.3. (AFAIR the base of 5.3 was spacewalk 0.5). The only thing that changed from the client side was the activation key. There also have been a change for RHEL5.5 and sat 5.3 (too lazy to search for the errata). The yum errata was published weeks before RHEL5.5 hits the street. @Miroslav and the other RHN Sat/Spacewalk developers: Can you promise to announce incompatible changes early enough? If yes, CentOS can include the stuff immediately. Quoting Karan @ http://lists.centos.org/pipermail/centos-devel/2010-January/005361.html <quote> A very large number of pople who use centos, do so with little or no previous understand of linux or even the basics of systems management - we need to keep those people in mind as well. The problem that we have had, in the past, is that installing yum-rhn-plugin brought in loads of rhn\* packages as well, which in turn would cause traffic to rhn.r.c. Also, given that rhn itself is a rhel connected service, the view we took was that there is no need for that functionality in the distro at all. </quote> This is partially true. Another fact about CentOS is IMHO, that a lot of people and companies are using CentOS as a testbed for RHEL. I guess that even more users of spacewalk are using it a a replacement for a RHN sat, since RH does only provide 30 days test licences for RHN sat. Companies have (more or less) large test-environments with CentOS. For those companies it would be a great benefit to have those packages in stock CentOS. Benefits for my self: My daily work is with RHEL and RHN Satellite. In meanwhile I have quite a good to excellent knowledge of RHN sat and its future (I'm a git reader). This is mainly due to the existence of spacewalk. At the moment implementing a complete testbed consisting of CentOS AND spacewalk means quite a lot of work, due to to missing rhnlibs and friends in CentOS. Conclusion: With a very small patch as Miroslav suggested to avoid bothering rhn.redhat.com we can have a OS with is attracting to more people. If I can help maintaining the stuff, let me know, I'll do my best.... Thanks, Luc

two kickstarts I use around here
by Manuel Wolfshant 10 May '10

10 May '10

hello As asked by Karanbir, please find attached two kickstart files that I use. One is used for servers and does an [almost] minimal install (with support for ssh -Y); the other one is almost 100% the actual ks that I use for the workstations (it adds some 3rd party software, beyond what Centos provides).

Talk about existing forums
by Karanbir Singh 07 May '10

07 May '10

hi guys, One of the things that came up from the last chat about the language specific websites, was that there was no one on that call who actually used the forums. With the help of Akemi, I've been able to setup a meeting for the existing english forum moderators to come together and have a chat about: 1) what we have right now 2) Whats broken 3) whats really good 4) where they would like the forums to be in the next 6 months 5) Where they would like the forums to be in the next 12 months 6) The idea of 'English' as being just another language Its a bit short notice, but the meeting is setup to happen on Wednesday 9th Dec at 2300 UTC. Its the only time that worked for all concerned - in the next few weeks period. Apart from the existing forum moderators, anyone interested in the conversation is more than welcome to come along. Lets all sync up at 22:50 on #centos-devel(a)irc.freenode.net and take it from there. Also, lets try and timebox initial discussion to 40 min with a further 10 min after that to summarise and plan future actions. - KB

removing inaffective SAN partitions from the system .....
by Jagan Kommineni 19 Apr '10

19 Apr '10

Dear All, I have installed CentOS release 5.2 (Final). EMC SAN partition is mounted by using EMC Powerpath for resolving multiple paths. I was able write and read data over to SAN partition without any issues. Subsequently I have unmounted EMC SAN partition from the system and deleted LUN using Navisphere user interface. After rebooting system, I still see SAN mappings in system. Here is the affected partition mappings .... ============================== cat /proc/partitions ============================== major minor #blocks name 8 16 1048576 sdb 8 48 1048576 sdd 8 80 1048576 sdf 8 112 1048576 sdh ============================ When I try to print information using parted, I am getting the following information .... ========================================================================================= #parted /dev/sdb GNU Parted 1.8.1 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Error: Unable to open /dev/sdb - unrecognised disk label. (parted) ============================================= I would like to get rid of partition mappings from the system. Anyone has any solution for this problem please. with regards, Dr. Jagan Kommineni Ludwig Institute for Cancer Research Parkville Dr. Jagan Kommineni Ludwig Institute for Cancer Research Parkville This communication is intended only for the named recipient and may contain information that is confidential, legally privileged or subject to copyright; the Ludwig Institute for Cancer Research Ltd does not waive any rights if you have received this communication in error.
