Red Hat Enterprise Linux 6 is out

 | Wednesday, 10. November 2010 23:34

Red Hat Enterprise Linux 6 is out, at long last. Also IMHO lot of Code come from Fedora 13 not from Fedora 12 also there are lot of Kernel features from 2.6.32 until 2.6.34. The Release is pretty good beside some Problems with the Cluster we found ( it’s running but not really ready for Production ), hope they fix that very soon. Also certification is not there from the Major ISV’s.

Over 3.5 Years after RHEL5, RHEL6 came out. For me I think Red Hat will get into bigger Problems with the Major Releasecycle sooner or later. If they don’t Release a Major Release every 2 -max. 3! Years they don’t get the necessary Hardware update into they’re Kernel. From my side I don’t understand that they wait so long. So at the End the Releaseschedule for RHEL is complete not plannable from outside.Means also the ISV will have some Problems.

Also the Subscriptions have change significant ! http://www.redhat.com/rhel/purchasing_guide.html
Now you have to Subscribe per two – sockel ! also there are 3 diffrent Version for Virtual Guest inclusion. Then more or less all important packages are separate als Add-On ( don’t really understand what is where included )

–> conclusion we are back to RHEL 4 Times


Also the Add-On EUS has two variants EUS and ELS, where EUS extend the Lifecycle of a minor Release the ELS extend the Lifecycle of a Major Release ! BUT the exclusions are Big if you go to Site:

http://www.redhat.com/rhel/server/extended_lifecycle_support/exclusions/

http://www.redhat.com/f/pdf/RH_ELS_CustomerDatasheet.pdf

then you found out that Cluster and GFS for RHEL4 are not supported anyway –> How should buy such a ELS ? For which Server do I need a ELS ? Not for a Single Server, this I could maybe migrate.

Atix Open-Sharedroot in Fedora 12

 | Tuesday, 11. August 2009 23:07

End of July  the Open-Sharedroot Feature was accepted in Fedora 12:

–> https://fedoraproject.org/wiki/Features/Opensharedroot

That is really a good news for Open-Sharedroot Fans like me. So the possibility that OSR will be included in Red Hat Enterprise Linux 6 is 100% higher.

Also if it not included the Support Problematic is extrem lower.

I really hope that OSR make it to the final Fedora 12 in October

Hilti erhält Red-Hat-Auszeichnung für Linux Migration

Hilti wird fĂĽr die Migration seiner Applikationen SAP CRM und SAP ERP auf ein Red-Hat-System mit einem Innovation Award 2009 ausgezeichnet.

Ich denke wir haben diesen Award verdient durch harte Arbeit die letzten 3 Jahre. Trotz allen Widrigkeiten und vielen Steinen haben wir unsere Entscheidung nach Linux zu migrieren erfolgreich durchgezogen.

Red Hat Enterprise Linux 4.8 erschienen

 | Friday, 22. May 2009 0:28

Jetzt sollte es keine neuen Funktionen / Backports oder andere Feature mehr für RHEL4 geben, da wir uns  im Production 2 Phase befinden.

Wenn man sich so die Release Notes durchliest oder den changelog einzelner rpm’s anschaut fragt man sich wie das ĂĽberhaupt jemals funktoniert hat.

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/4.8/html/Release_Notes/index.html

Zum Glück können wir diesen Release auslassen da wir jetzt EUS Support haben. Auch frage ich mich ob alle unsere hotfixes im RHEL4.8 drin sind. Der rgmanager hat sicher noch nicht alle fixes erhalten. Was mir aufgefallen ist das scheinbar der OFED Stack 1.4 integriert wurde, heisst die Infinibandtreiber dürften recht aktuell sein.

RHEL 5.3 / RHEL 4.8 beta

 | Thursday, 26. March 2009 23:09

Die Minor update Version macht einen sehr guten Eindruck, ausser das sich wieder ein paar Fehler ( regressions ) eingeschlichen haben die wirklich nicht Lustig sind. Mit diesen wenigen Fehler wird die Arbeit vieler zunichte gemacht. Da nützen die schönsten neuen Features nichts wenn altes auf einmal nicht mehr geht.

Ich hoffe wirklich sehr das die Red Hat noch mehr in das Regression Testing investiert, den wiederkehrende Fehler oder Funktionen die auf einmal nicht mehr funktonieren sind einfach extrem schlecht.

Am 20.01.2009 haben wir uns wieder zu einem Erfahrungsaustausch in Adliswil getroffen. Wie immer ging es um Erfahrungen im Bereich Enterprise Linux. Da gibt es immer noch sehr wenig Informationen, darum war dieses Mal das Echo einfach überwältigend. Ich musste sogar einen neuen Raum organisieren.

Auch haben wir abgestimmt das wir uns dieses Jahr nochmal treffen wollen da das Bedürfniss recht gross ist.  es machen schon

Red Hat Cluster Suite fencing / Dump Problem

 | Tuesday, 30. September 2008 22:52

Because the Red Hat Cluster do fencing with Power off we have long-time ago a fencing Problem. Means if we fence one Member and this one has to write a dump we have only arround 120s to write his dump to the swap file, then he will be fenced with power-off. during this time the Cluster will be freezed because we don’t no the exact status from the member.

To reduce the freeze time, we need a extrem fast local swap storage. So I saw from fusionio.com that they sell a SSD internal disk with 600mb/s radom write ( http://www.fusionio.com/PDFs/Fusion specsheet_v16.pdf )! Thats extrem fast, so I thinking to buy one. But that is one drawback –> price are also very high around 30$/GB and I’m not sure if its works with diskdump.

Red Hat Enterprise Linux 4 update 6 / RHEL 4.6

 | Friday, 26. September 2008 0:00

We have all our Servers arround 100 migratated to RHEL 4.5, now with our Second Bigest System we must for Support Reason ( z-stream, extended support is not GA ! ) go for a newer Version we choice 4.6 because we don’t had the time to test all with 4.7.

But since we are live with the system and also a week befor we have a lot of Problems with this Version, it looks like the nightmare form 4.3 / 4.4 come back again.  One Point is better, we have a Red Hat TAM now and he do the complete org things for us now. We also go in proactive Testing for 4.7 now, because there maybe a lot of bugs fixed now.

But all in one I’m not really happy with the QA from Red Hat, I also try to get in touch with the QA responsible from the Red Hat Cluster Suite.
