Create CentOS 6 system as "clone" of another - with LVM and different disk sizes
by Toralf Lund 16 Apr '18

16 Apr '18

Hi, I just found myself having to set up a new CentOS 6 system with a nearly identical configuration to an existing host, so I thought I would just 1. Do a minimal install to set up partitions etc. on the new system. 2. Create an image of the existing system using Clonezilla (http://www.clonezilla.org) 3. Run a Clonezilla restore on the new system. - as I though it would be a lot simpler than replicating the exact package selection, installing the same users, doing the same manual config edits (which are required) etc. It turns out that it wasn't quite as easy, though. The problem is that the system use LVM2 volumes for the filesystems, and the new host has a slightly smaller disk than the other, and Clonezilla seems unable to restore to a volume that's smaller than the one that was cloned - even if the actual data fits. I guess I could temporarily reduce the LVM volume sizes on the existing units and clone again, but I'd rather not if I can avoid it. Just copying file-by-file could be an option, too, but I somehow feel less comfortable doing that than the above; there is something about the way I could end up with a mixture of my "minimal install" and the "cloned" data, I suppose. Does anyone have any other ideas about how I might achieve what I want? - Toralf

YUM4/DNF for CentOS updates announcement
by Marek Blaha 13 Apr '18

13 Apr '18

I am pleased to announce some significant updates to our ConfigManagement Special Interest Group for YUM4. This provides YUM4, based on DNF technology, for testing on CentOS Linux 7/x86_64. These updates are based on feedback from our prior test release last October. It includes signed packages, core DNF plugins, and uses a version of RPM very similar to and compatible with the upcoming version of CentOS 7.5. This initiative is based on a partnership with the upstream YUM and DNF maintainers for the future of package management. Our testing thus far indicates no major problems, but we would love to find out how it fits into your existing YUM 3 workflows. So please consider filling out the short survey - your feedback helps us all get better. YUM 4 provides significant improvements such as fast dependency resolution and a stable, documented API. See the references below for detailed improvements. We have made every effort to preserve the existing end-user experience that is available with YUM 3. This is the primary reason for making YUM 4 available for testing now. For detailed information and instructions to install YUM4 on your CentOS machine, please visit our wiki: https://wiki.centos.org/SpecialInterestGroup/ConfigManagementSIG/YUM4 And remember to submit feedback in the short survey to help us understand how it can be improved further: https://goo.gl/forms/H1SL1HaEjdV9EUGH3 Many thanks to the CentOS Project team for their assistance in making this happen! Regards, Marek Blaha

Help with yum
by Paul R. Ganci 13 Apr '18

13 Apr '18

I just did a fresh minimal install of centos 7 on new hardware. While playing around with window systems I removed X windows like so: >yum remove "X Window system" and then tried to re install >yum group install "X Window system" which gives this error: Maybe run: yum groups mark install (see man yum) No packages in any requested group available to install or upgrade I tried running: >yum groups mark install "X Window system" and get the same message. I tried different permutations removing the "s" on groups. Nothing seems to bring back the yum "X Window system" group. Can anyone help me resolve this issue and tell me what I did wrong? Thanks for your help. -- Paul (ganci(a)nurdog.com) Cell: (303)257-5208

motion
by m.roth＠5-cent.us 12 Apr '18

12 Apr '18

Got a CentOS 7 box running motion. Selinux is complaining that one of the scripts motion runs is mislabeled. Here's what it is. system_u:object_r:nfs_t:s0 /home/motion/bin/on_move_end Now, ~motion is NFS mounted, and we've got use_nfs_home_dirs --> on, so what *would* the proper label be, or do I really need to create a policy for this? mark

Windows PC PostScript printer driver -> CUPS data import fails
by Gary Stainburn 12 Apr '18

12 Apr '18

Hi all, For some years now I have been using a simple system I found online which allows me to easily import data from Windows Programs. Hopefully others out there are using the system and already have found the answer to my problem. I have installed on my Centos server a virtual CUPS printer which receives a PS file, and then runs 'ps2pdf' and 'pdftotext -layout' to end up with a text file. On the Windows PC's it's simply a case of installing a printer pointing to this server, and using the HP Colour Laster 2800 PS drivers. Now to my problem. We have finally moved onto Windows 10, and now when I try to install the printer that model printer is no longer available. When I try similar HP Colour Laser PS drivers the ps2pdf command fails. [root@lou inet]# ps2pdf 20180412_104403_tcards.ps GPL Ghostscript 9.14: Unrecoverable error, exit code 1 [root@lou inet]# The PDF contains: ERROR: invalidfileaccess OFFENDING COMMAND: .findfont OPERAND STACK: r /usr/share/X11/fonts/Type1/UTBI____.pfa --nostringval-- true NimbusMonL-Regu Courier --nostringval-- Courier 4544317 Courier Font Courier Has anyone else had this problem, and have they managed to find a solution?

Does Huawei break the license of CentOS?
by Genghuang Wang 12 Apr '18

12 Apr '18

Hello, CentOS team and everyone who cares about CentOS, Huawei release an Euler OS, which is an distribution based on CentOS. http://developer.huawei.com/ict/en/site-euleros/euleros-introduction According to CentOS's statement, CentOS is distributed under the GPLv2 License. http://mirror.centos.org/centos/7.4.1708/os/x86_64/EULA The GPL license requires the modified version to be open-source AND release in the GPL license, as well. However, Huawei break the GPL license by close-source and replace the license with their proprietary one. How do I find it? Well, I download the so-called Euler OS from http://developer.huawei.com/ict/site-euleros/euleros/repo/yum/2.2/os/x86_64… And install it in the virtual machine. From the following path: /usr/share/euleros-release/EULA /usr/share/eula/eula/eula.en_US I find that it is NOT the GPL license, but Huawei's own license. So is Huawei breaking the license of CentOS?

Ansible repository shenanigans in EL7
by James Hogarth 11 Apr '18

11 Apr '18

For those not aware ansible has been deprecated in RHEL7 from the extras repository. In the RHEL specific world it's now in an optional "product" (basically an optional subscription) that is part of any RHEL subscription, but it's opt in. As a result ansible is back in the EPEL7 repository for 2.5.0+ , having been removed for ansible 2.4.2 when it got introduced to the RHEL extras repo. I have no idea what, if anything, the CentOS team will do with the ansible in the CentOS7 extras repository.

Next major version of Firefox on RHEL/CentOS ?
by James Pearson 11 Apr '18

11 Apr '18

I know CentOS don't have inside info on what Redhat may or may not do in the future - plus Redhat don't usually announce publicly what their future plans are - but on the off-chance that someone on this list may know: Does anyone know what Redhat are likely to do with the next major release of Firefox on RHEL (and hence CentOS) ? The reason I ask, is that RHEL has been supplying the 'ESR' (Extended Support Release) version of Firefox - which Mozilla supports for about a year - and RHEL moves to each new ESR version before Mozilla drops support for the previous version. Up until the current version of ESR (52), the major versions have been mostly compatible, but the next release of ESR (60) has some major changes - which include: * No support for NPAPI plugins - except for Flash - i.e. no support for plugins like Java etc * No support for XUL/XPCOM/legacy add-ons - will only support 'WebExtensions' * Requires gtk3 run-time support - which isn't available with RHEL/CentOS 6 (currently Firefox for both el6 and el7 use the gtk2 run-time libraries) I know it's a long shot, but I'm just trying to work out what changes I will need to make when ESR 52 reaches its EOL in August this year ... Thanks James Pearson
