After Crash dracut kernel
by Tim 14 Jan '15

14 Jan '15

Hello, I have two identical servers in hardware. I installed both with CentOS. I did LVM snapshots before updating to test LVM merging. On one server I merged all filesystem's during boot because they where mounted when I merged. The other server I did the snapshots, made my installations and configurations and made no merge because it worked on the other server. But I forgot to delete the snapshots and: n the night the server crashed. It rebooted to recovery kernel because it can't find the lvm volumes (module dm_snapshots was missing). Both servers have a difference. When they start one says CentOS (Core) at the end of the loading bar. The other with the crash says sth. about a dracut-Kernel while loading. What do I have to look for? Partitioning scheme on both servers: /boot: sda1 /: lvm /usr: lvm /var: lvm Swap: lvm Thanks in advance Tim

Those > in control of RHEL get to say what enterprise means. This is, of which you are no-doubt quite cognisant, a straw-man augment. Nowhere in this discussion has anyone defined 'rules' or claimed that rules exist, in Merriam-Wester or elsewhere, in whatever form you imagine them to take. > > The time to argue about the merits of these changes is long past. > Muster whatever arguments you like, you cannot change the fact that > CentOS 7 includes these technologies.

This issue, as I see it, is not about CentOS-7 per se. It is about the path that RHEL seems to be following at the moment and what that might mean to current users sometime in the future. This forum is where I find those who share my interest in RHEL, albeit in the form of CentOS. I am seeking their views on the matter. I do not expect a solution here. Nor would I look for one on any of the multitudinous mailing lists associated with Fedora. A solution postulates a problem to solve. I am simply checking whether the RH environment suits our needs and whether it is likely to continue to suit; or is likely to change in ways that might prove most inconvenient, for us. We moved to RH5 (or 6 it was a long time ago, pre-RHEL) from HPUX. That change was driven equally by economics and a political change at HP with respect to its clients. It took the better part of five years to complete. If RHEL is changing such that 8 will be less useful than 7 or more considerably expensive to deploy than we can reasonably afford then we need to be looking now for a replacement. > >> I am not at all certain that >> back-porting security fixes to obsolescent software is a profitable >> activity when often for much the same effort, if not less, the most >> recent software could be made to run on the older release without >> adverse effects elsewhere. > > Please point to an example of an OS or OS-like software distribution > that does this. Why is that necessary? I am expressing my opinion about the value derived from the resources expended. I was not aware that I am not permitted to express such unless I can point to a representative distribution which somehow manifests an approach which affirms that opinion. That seems a little like saying only a tailor can comment on whether the emperor is wearing any clothes. In any case, it seems to me that the rather recent innovation of software collections indicates that perhaps I am not alone in that observation. As it happens a most useful, to me at least, piece of information was revealed in the course of this thread. That was the existence of a server based stream for Fedora. I have downloaded that ISO and intend to install it on a VM in the near future. If the results of that investigation prove satisfactory then that will go a long way to alleviating the doubts that my, admittedly limited, experience with CentOS-7 has engendered thus far. -- *** E-Mail is NOT a SECURE channel *** James B.

configure two bonding interfaces via kickstart
by Benninger Frédéric 14 Jan '15

14 Jan '15

hello, With CentOS 6.6, I try to configure two bonding interfaces via kickstart, but it works only with bond0, I don't understand why I can't configure bond1 the same way. I found this old post: http://lists.centos.org/pipermail/centos/2013-March/133439.html I have exactly the same problem. Who found the trick? best regards Frédéric Benninger

Re: [CentOS] Making custom USB install media
by Matt 14 Jan '15

14 Jan '15

Almost. I've read that, and I can get it to work. I guess I could phrase my question as "Given that the default image for 6.6 and 7.0 do this, how do I make custom media that does it to?" When I make custom media, it only works off an actual DVD. I need help making custom media that has that USB/EFI magic in it.

Making custom USB install media
by Matt 14 Jan '15

14 Jan '15

Hey List, I apologize for how broad this may be, but hopefully someone here can help me out. I need to make custom kickstart installers to be used in the field to install microservers (Intel NUCs, EFI boot) that don't have optical drives and may not have internet connections. I can make a custom ISO just fine using the pretty common steps, specifically following what's here: http://smorgasbork.com/component/content/article/35-linux/151-building-a-cu… My custom kickstart is on the disk, and along with all my packages, and everything works great on a VM as a CD image. The problem is I can't get this to install from USB. I can get it to boot from USB using the isohybrid tool, but the installer fails, can't find the squashfs image. I don't think this is the right way to do it. I know the CentOS 7 (and I believe 6.5) images have a "special" EFI partition that I believe is why USB works with the base image. The problem is I can't really find any information on how this works or how to recreate it. When I run fdisk -l on the image (as a loopback device) I see that the main image is on a partition marked as none, and then there's an EFI partition with start and end points actually inside the first partition? I'm afraid I don't really know what this is doing, or how to go about recreating. Can anyone explain this to me or point me at some documentation? Am I missing something obvious, like say the old Revisor tool that I should be using to make my life much easier? Any help would be much appreciated, -Matt

Scope of testing done by CentOS Development Team
by Somers-Harris, David | David | OPS 14 Jan '15

14 Jan '15

Hello, What types of tests does the CentOS Development Team do for software in its repositories? Where does it get its test catalog from? I want to create a testing process which is equal to if not more rigorous that the CentOS process for any third party software we use. For example, if I install the php-mysqlnd package from the Remi repository, I want to test it just as carefully as the php-mysql package has been tested before I get it from the CentOS repository. If somebody can point me in the right direction I'd appreciate it. Thanks! David

When will CentOS Publish Errata?
by Somers-Harris, David | David | OPS 14 Jan '15

14 Jan '15

Hello, Currently The CentOS project publishes errata on its CentOS Announce mailing list. In order to import this into a package management system (like Katello on The Foreman), one needs to parse the mailing list and convert it into XML before importing it. This is done to some extent on http://cefs.steve-meier.de/ but some more legwork needs to be done before The Foreman can understand the errata like it does natively for RHN. I have heard rumour that The CentOS project is planning to publish Errata in the same way that Red Hat does, but I haven't been able to find anything on the Internet about this. Does anybody know if The CentOS Project has indeed declared such intention, and when they plan to do this? Side Note: Interestingly enough, I've noticed that EPEL has started to add errata data to their repositories. Thanks, David

2460x1440 video card recommendation
by Frank Cox 13 Jan '15

13 Jan '15

Can someone recommend a video card that's capable of driving a monitor at 2560x1600 or 2560x1440 and just works with Centos 7 without requiring any outside video drivers? I would prefer to stay with the built-in video drivers that are included with Centos 7 if possible; I don't play games and such, so I'm not looking for high performance 3D -- I just want a high resolution desktop. I'm currently looking at a BenQ GW2765HT which is 2560x1440, though I might end up with something else in the end. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

CentOS 6.6 64-bit won't install on a 3 TB disk
by Gilbert Sebenste 13 Jan '15

13 Jan '15

Hello everyone, I'm having an issue getting a C6.6 install to work on a 3 TB dual hard drive system, raid 0. I'm hoping that someone here can help. So, I install as normal, but then reboot, and it comes to a grub prompt. Going into the system via Linux rescue, I see that most of the files dealing with the kernel haven't been installed. I asked the maker of the server and he said that they have noticed this happen recently. A solution is to put the kernel files on a thumb drive, and then point the OS to look for them there. I have yet to try it, but is there a better way to deal with this issue that anyone else has done?

You will see the same effect on MicroSoft Domains with users using roaming profiles. They leave one host with FF open and go to another, log on and try, vainly, to start FF in the new session. I presume this has to do with preventing destructive overwrites of the user's profile but it is annoying. Not a Linux problem though. -- *** E-Mail is NOT a SECURE channel *** James B.
