In place upgrade of RHEL 8 Beta to CentOS 8?
by Benjamin Smith 10 Apr '19

10 Apr '19

I'm about to rebuild a server, currently running CentOS 6. If I have to do an OS reinstall, my intention is to upgrade, as it's the oldest OS server under my purview. As this server is pretty low visibility, I'd like to see if I can start using EL 8 instead of 7.x. In the past, I was able to switch between different OS variants by simply changing out the yum.d files; EG: RHEL 6.x becomes CentOS 6.x by replacing a single RPM and doing a `yum -y clean all; yum -y update` without issue. How likely is it that similar functionality will exist switching from RHEL 8 Beta to CentOS 8 final? Google pounding provided little info. I couldn't even find useful information for the transition from RHEL 7 Beta. Ben

MegaRAID, and creating a RAID 1 while live
by mark 10 Apr '19

10 Apr '19

I've started searching, but if anyone here has a link.... I *just* discovered yesterday, to my dismay, that a previous admin built a box that has four hot-swap bays as two as RAID 1... and the other two as RAID 0. Honest, I thought I was pulling the failing drive out of a RAID 1, not that the RAID 0 contained all the websites for a production box.... So, what I want to do is this: it's a Dell, with a PERC 710. Let's call the two drives I'm dealing with sdb and sdc. With mdadm, what I'd do is 1. copy what's on the the RAID 0 of sdc to the RAID 0 of sdb, 2. create sdc as RAID 1, with a drive missing. 3. copy everything from sdb to sdc, and finally. 4. kill the RAID 0 of sdb, and add it as the missing drive to the new RAID 1. And, all with MegaCli64.... Links? mark

Kernel panic after removing SW RAID1 partitions, setting up ZFS.
by Benjamin Smith 10 Apr '19

10 Apr '19

System is CentOS 6 all up to date, previously had two drives in MD RAID configuration. md0: sda1/sdb1, 20 GB, OS / Partition md1: sda2/sdb2, 1 TB, data mounted as /home Installed kmod ZFS via yum, reboot, zpool works fine. Backed up the /home data 2x, then stopped the sd[ab]2 partition with: mdadm --stop /dev/md1; mdadm --zero-superblock /dev/sd[ab]1; Removed /home in /etc/fstab. Used fdisk to set the partition type to gpt for sda2 and sdb2, then built *then destroyed* a ZFS mirror pool using the two partitions. Now the system won't boot, has a kernel panic. I'm remote, so I'll be going in tomorrow to see what's up. My assumption is that it has something to do with mdadm/RAID not being "fully removed". Any idea what I might have missed? Here's a screenshot of the panic http://effortlessis.com/images/IMG_0705.JPG

We will once again be holding the CentOS Dojo at Boston University, on the day before DevConf.US 2019. The details of DevConf.US are at https://devconf.us/ and the details of the CentOS Dojo are at https://wiki.centos.org/Events/Dojo/DevConfUS2019 The call for presentations is now open, and will close May 1st. Registration is now open. It's free to attend, but we need an attendee count for planning purposes. You can see last years schedule - https://wiki.centos.org/Events/Dojo/DevConfUS2018 - for an example of what kind of presentations we might have. And we'd love to hear from you - your stories of running your infra on CentOS, the projects that you're working on, and interesting challenges you've had. Please do submit your talk proposals! Based on requests last year, we expect to do a lightning talks session, with 5-minute impromptu talks for those who don't have a full presentation.

Just remove xapps (yum remove xapps) and note which packages are removed with it.On my systems these packages were removed: Packages Altered: Erase python2-xapps-overrides-1.0.4- 13.el7.x86_64 @epel Erase python34-xapps-overrides-1.0.4- 13.el7.x86_64 @epel Erase xapps-1.0.4- 13.el7.x86_64 @epel Erase xed-1.6.2- 3.el7.x86_64 @epel Then reinstall xapps, xed, python2-xapps-overrides andinstall python36- xapps-overrides like so: Packages Altered: Install python2-xapps-overrides-1.0.4- 14.el7.x86_64 @epel Install python36-xapps-overrides-1.0.4- 14.el7.x86_64 @epel Install xapps-1.0.4- 14.el7.x86_64 @epel Install xed-1.6.2- 3.el7.x86_64 @epel <(*) Jyrki

Automatic updates applying after reboot
by Gestió Servidors 08 Apr '19

08 Apr '19

Hello, I have noticed something I consider "a bug". Running a CentOS-7-x86_64 with kernel 3.10.0-327.13.1 and Gnome 3.14.x, my systems detects some available updates, notifies me at top bar and, if I close session, Gnome ask me if I want to apply these "pending" updates and, then, execute "shutdown" or "restart". My questions/problems are two: * this automatic updates check runs in both root session and not a root session, so if a "normal" user login, that user could logout and APPLY updates (system reboots and, during boot, updates system). I consider these situation VERY DANGEROUS, because a normal user should not be able to apply updates * what daemon controls automatic updates? pakagekit? What RPM? gnome-packagekit-updater? I NEED to disable this feature. By the moment, the only solution I have found is disablinig packagekit daemon (systemctl disable packagekit) and remove RPM "gnome-packagekit-updater". Thanks.

Issues when updating CentOS 7
by Stelian Iancu 05 Apr '19

05 Apr '19

Hi all, I wanted to update my CentOS 7 install this morning and I started getting the errors from below. Any ideas on a fix? They seem to be related to cinnamon which I actually don't use at all (the machine was prepared by our IT at work and they install both Gnome and Cinnamon by default). Since I don't use it, I guess an option would be to remove it altogether and then I will probably not have the update issues anymore. But I would still try to find a proper way to solve this Thanks in advance!

Seek some help on operating system drivers. Thanks!
by JICHUN LIU 05 Apr '19

Hello, I am a user of CentOS 7.6. I came here for help. I recently bought a microserver called HPE Proliant MicroServer Gen10(X3216 APU). CentOS 7.6 was installed for it. I found that the fan of the machine would keep turning and the noise was very loud. I searched everywhere but I couldn't find any way out. Pardon my ignorance showing. I don’t know where to seek help. When I use sensors-detect: Sorry, no sensors were detected. Either your system has no sensors, or they are not supported, or they are connected to an I2C or SMBus adapter that is not supported. If you find out what chips are on your board, check http://www.lm-sensors.org/wiki/Devices for driver status.
