Accidentally nuked my system - any suggestions ?
by Nicolas Kovacs 05 Dec '18

05 Dec '18

Hi, My workstation is running CentOS 7 on two disks (sda and sdb) in a software RAID 1 setup. It looks like I accidentally nuked it. I wanted to write an installation ISO file to a USB disk, and instead of typing dd if=install.iso of=/dev/sdc I typed /dev/sdb. As soon as I hit <Enter>, the screen froze. I tried a hard reset, but of course, the boot process would stop short very early in the process. Now, I have backups of the important stuff of course, so no real catastrophe. But it would be nice if I could get back the data from my disk directly. I booted a rescue disk (Slax 9.6.4) and I can see my disks as well as raid arrays /dev/md125, /dev/md126 and /dev/md127. Oh, my partitioning scheme is manual and quite simple. Everything is RAID 1, I have a /boot array on /dev/sda1 + /dev/sdb1, swap on /dev/sda2 + /dev/sdb2 and / on /dev/sda3 + /dev/sdb3. I tried to mount /dev/sda3 directly from the rescue disk: # mount /dev/sda3 /mnt But I only get this: mount: unknown filesystem type 'linux_raid_member' I'd be very grateful for suggestions.

7.5 -> 7.6 problems
by Gregory P. Ennis 05 Dec '18

05 Dec '18

To all, I started the process of updating some of our systems from 7.5 to 7.6. Most of the servers had no problems, but several of the desktops had some difficulties. I was required to perform several yum commands to update as much as possible in the format of yum update a* then b* etc. Then after I got everything updated that would update in this manner and after the use of "rpm -Va --nofiles --nodigest" and with the use of yum update --skip-broken I am getting the following that would not update : Packages skipped because of dependency problems: libvirt-bash-completion-4.5.0-10.el7_6.3.x86_64 from updates libvirt-client-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-config-network-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-config-nwfilter-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-interface-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-lxc-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-network-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-nodedev-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-nwfilter-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-qemu-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-secret-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-core-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-disk-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-gluster-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-iscsi-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-logical-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-mpath-4.5.0-10.el7_6.3.x86_64 from upd libvirt-daemon-driver-storage-rbd-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-driver-storage-scsi-4.5.0-10.el7_6.3.x86_64 from updates libvirt-daemon-kvm-4.5.0-10.el7_6.3.x86_64 from updates libvirt-devel-4.5.0-10.el7_6.3.x86_64 from updates libvirt-libs-4.5.0-10.el7.x86_64 from base libvirt-libs-4.5.0-10.el7_6.2.x86_64 from updates libvirt-libs-4.5.0-10.el7_6.3.x86_64 from updates libvirt-python-4.5.0-1.el7.x86_64 from base Is there something I can do to finish this process or is this just related to a repository problem. -- Greg Ennis

by Jerry Geis 05 Dec '18

05 Dec '18

Hi all... Great work on 7.6! I updated a number of boxes - all good! This "one" server I lost connection through the internet or something... Anyway 702 transactions left and its not happy. When I run yum-complete-transaction I get "many" Removing man-db.x86_64 0:2.6.3-9.el7 - ud from the transaction Removing man-db.x86_64 0:2.6.3-11.el7 - u from the transaction Removing python-ethtool.x86_64 0:0.8-5.el7 - ud from the transaction Removing python-ethtool.x86_64 0:0.8-7.el7 - u from the transaction Removing iprutils.x86_64 0:2.4.15.1-1.el7 - ud from the transaction Removing iprutils.x86_64 0:2.4.16.1-1.el7 - u from the transaction Removing strace.x86_64 0:4.12-6.el7 - ud from the transaction Removing strace.x86_64 0:4.12-9.el7 - u from the transaction and then nothing happens.... (This is just a short list) many are printed. Thoughts? What next? Jerry

Hi list, I'm trying to understand SELinux on C7. I encountered problem running bacula when system is enforced. The problem is when bacula try to run BeforeJobScript. In this script there is an occourrence to systemctl stop httpd and hostname command and I got error on permission on this 2 commands. Reading RHEL 7 SELinux Guide seems that I need a domain transaction but I don't know how to solve this. Can someone put me in the right direction? Thanks in advance.

Dell server dropping packets
by Jerry Geis 04 Dec '18

04 Dec '18

Hi All - I have a Dell R430 server running CentOS 7.5 that is dropping packets on the network. Its connected to Cisco switch at AUTO for the port. The server reports 1000M on the network. I even changed the setting for the switch to 1000M full, that did not seem to make a difference either. What else might I look at as to why its dropping packets? Its mainly 90'ish percent idle. so not doing much at this time. I have no idea what else is happening on the network. I set a windows box on the same network and just did a "ping" to the server and once in a while it lost the packets or my putty connection dropped etc... Thoughts? Ideas? Thanks! Jerry

Today's Topics: 1. Release for CentOS Linux 7 (1810) on the x86_64 Architecture (Johnny Hughes) 2. Release for CentOS Linux 7 (1810) on aarch64 i386 ppc64le and power9 (Pablo Sebasti?n Greco) 3. Release for CentOS Linux 7 (1810) on armhfp (Pablo Sebasti?n Greco) ---------------------------------------------------------------------- Message: 1 Date: Mon, 3 Dec 2018 09:18:22 -0600 From: Johnny Hughes <johnny(a)centos.org> To: CentOS-Announce <centos-announce(a)centos.org> Subject: [CentOS-announce] Release for CentOS Linux 7 (1810) on the x86_64 Architecture Message-ID: <1cf9af45-fd45-b32e-0aea-eae0ff9966d1(a)centos.org> Content-Type: text/plain; charset="utf-8" We are pleased to announce the general availability of CentOS Linux 7 (1810) for the x86_64 architecture. Effectively immediately, this is the current release for CentOS Linux 7 and is tagged as 1810, derived from Red Hat Enterprise Linux 7.6 Source Code. As always, read through the Release Notes at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7 - these notes contain important information about the release and details about some of the content inside the release from the CentOS QA team. These notes are updated constantly to include issues and incorporate feedback from the users. ---------- Updates, Sources, and DebugInfos Updates released since the upstream release are all posted, across all architectures. We strongly recommend every user apply all updates, including the content released today, on your existing CentOS Linux 7 machine by just running 'yum update'. As with all CentOS Linux 7 components, this release was built from sources hosted at git.centos.org. In addition, SRPMs that are a byproduct of the build (and also considered critical in the code and buildsys process) are being published to match every binary RPM we release. Sources will be available from vault.centos.org in their own dedicated directories to match the corresponding binary RPMs. Since there is far less traffic to the CentOS source RPMs compared with the binary RPMs, we are not putting this content on the main mirror network. If users wish to mirror this content they can do so using the reposync command available in the yum-utils package. All CentOS source RPMs are signed with the same key used to sign their binary counterparts. Developers and end users looking at inspecting and contributing patches to the CentOS Linux distro will find the code hosted at git.centos.org far simpler to work against. Details on how to best consume those are documented along with a quick start at : http://wiki.centos.org/Sources Debuginfo packages are also being signed and pushed. Yum configs shipped in the new release file will have all the context required for debuginfo to be available on every CentOS Linux install. This release supersedes all previously released content for CentOS Linux 7, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes. Note that older content, obsoleted by newer versions of the same applications are trim'd off from repos like Extras/ and Plus/ However this time we have also extended this to the SIG content hosted at mirror.centos.org, and some older End of Life content has been dropped. Everything we ever release, is always available on the vault service for people still looking for and have a real need for it. ---------- Download In order to conserve donor bandwidth, and to make it possible to get the mirror content sync'd out as soon as possible, we recommend using torrents to get your initial installer images: Details on the images are available on the mirrors at http://mirror.centos.org/centos/7/isos/x86_64/0_README.txt - that file clearly highlights the difference in the images, and when one might be more suitable than the others. sha256sum x86_64: 3213b2c34cecbb3bb817030c7f025396b658634c0cf9c4435fc0b52ec9644667?

CentOS-7-x86_64-NetInstall-1810.iso Information for the torrent files and sums are available at http://mirror.centos.org/centos/7/isos/x86_64 -------- Additional Images The container, Vagrant, Cloud and Atomic Host images are being prepared and will be released in the next few days. Look for an announcement posted to the centos-announce list for more information on availability for these in the coming days. ---------- Getting Help The CentOS ecosystem is sustained by community driven help and guidance. The best place to start for new users is at http://wiki.centos.org/GettingHelp We are also on social media, you can find the project: on Twitter at? : http://twitter.com/CentOSProject on Facebook at : https://www.facebook.com/groups/centosproject/ on LinkedIn at : https://www.linkedin.com/groups/22405 And you will find the core team and a majority of the contributors on irc, on freenode.net in #centos ; talking about the finer points of distribution engineering and platform enablement. ---------- Contributors This release was made possible due to the hard work of many people, foremost on that list are the Red Hat Engineers for producing a great distribution and the CentOS QA team, without them CentOS Linux would look very different. Many of the team went further and beyond expectations to bring this release to you, and I would like to thank everyone for their help. We are also looking for people to get involved with the QA process in CentOS, if you would like to join this please introduce yourself on the centos-devel list (http://lists.centos.org/mailman/listinfo/centos-devel ). Finally, please join me in thanking the donors who all make this possible for us. Enjoy the fresh new release! Thanks, Johnny Hughes
