Binutils-2.30-98.el8.aarch64 broken on raspberry Pi4
by Maurice Smulders 07 Apr '21

07 Apr '21

The recent update of binutils/binutils-devel on aarch64 totally breaks gcc. When running gcc over a simple program with main - executing it results in a SIGSEGV, as the _start prologue calls a NULL pointer. I haven't figured out yet how to build a new build using git.centos.org, but I noticed that there is a -99 variant out there... -90 worked fine. What's the quickest way to get this back to being operational? The instructions to build a new package look to be a bit scattered - and how can I build a working one if any update picks up a borked one... Maurice

Anyone looked into almalinux? I was sort of waiting for rocky, but I see from over the weekend on slashdot that almalinux stable is released. mark

Automatic clean /tmp folder
by Gestió Servidors 07 Apr '21

07 Apr '21

Hello, I have found some files/folders in /tmp that I thought they had to be deleted because of age. My /usr/lib/tmpfiles.d/tmp.conf is: # Clear tmp directories separately, to make them easier to override v /tmp 1777 root root 10d v /var/tmp 1777 root root 30d # Exclude namespace mountpoints created with PrivateTmp=yes x /tmp/systemd-private-%b-* X /tmp/systemd-private-%b-*/tmp x /var/tmp/systemd-private-%b-* X /var/tmp/systemd-private-%b-*/tmp And my /usr/lib/systemd/system/systemd-tmpfiles-clean.timer is: [Unit] Description=Daily Cleanup of Temporary Directories Documentation=man:tmpfiles.d(5) man:systemd-tmpfiles(8) [Timer] OnBootSec=15min OnUnitActiveSec=1d With these files I supposed that a file with more than 10 days in /tmp would be automatically deleted, but today I have found some files/folders with more than 10 days. What I have done wrong? Thanks.

Prevent Anaconda from switching root and swap partition
by Nicolas Kovacs 07 Apr '21

07 Apr '21

Hi, More often than not, when installing CentOS, I choose manual partitioning and then apply the KISS principle, with a very simple partitioning scheme that looks more or less like this: * /boot partition: 500 MB, ext2 * swap partition: equivalent to amount of RAM * root partition: available space, ext4 Now when I do this, Anaconda insists on switching my swap and root partitions, so instead of this: * /dev/sda1: boot partition * /dev/sda2: swap partition * /dev/sda3: root partition ... I get this: * /dev/sda1: boot partition * /dev/sda2: root partition * /dev/sda3: swap partition Up until now this hasn't bothered me much. But for my needs right now it does, because I need my root partition to be at the end of the disk, so it can be expanded later on. Anyone knows how I can prevent Anaconda from switching my root and swap partitions? What I'm doing right now is switching to a text console with Ctrl-Alt-F5, manually partition using fdisk, switch back to Anaconda and then rescan the disk, but it's quite a PITA. These are the moments where I miss the good old bone-headed Slackware installer. :o) Cheers, Niki -- Microlinux - Solutions informatiques durables 7, place de l'église - 30730 Montpezat Site : https://www.microlinux.fr Blog : https://blog.microlinux.fr Mail : info(a)microlinux.fr Tél. : 04 66 63 10 32 Mob. : 06 51 80 12 12

Problem with chromium 89.0.4389.82
by H 06 Apr '21

06 Apr '21

I am running CentOS 7 and just updated chromium to version 89.0.4389.82 from EPEL. Although this version was released a few weeks ago, I had had the previous version of chromium (88.0.4324.150) running for several weeks but it crashed and the new version was then loaded. The older version worked fine but this new one refuses to load certain, ie most, websites that the old version did not have a problem with - it is jus stuck waiting for the domain in question. Further, the version of Firefox I also have installed loads all of them without any problems which suggests there is not a problem with those sites, the DNS resolution, nor with my system apart from chromium. Rpm does not allow me to downgrade to the previous version and cannot find the previous version. I remember having a similar problem loading websites at least a year ago which, if I remember correctly, was due to some bug in chromium. Does anyone have a similar problem?

RHEL/Centos 8 power off issue
by R C 05 Apr '21

05 Apr '21

Hello, I have a laptop, in a docking station. When running RHEL/Centos 7 I could shut it down and power it off by using 'shutdown -h now' In did a new install of Centos 8 (and also RHEL 8) and when I do a "shutdown -h now" it just reboots (behaves the same as if I'd do a reboot). Is that a known issue? thanks, Ron

CentOS 8 issues.
by Frank Ramaekers 05 Apr '21

Okay, I made a foolish mistake a few months ago and upgraded my perfectly running CentOS 7 to CentOS 8 and have been struggling ever since. Looking to upgade to AlmaLinux or Rocky Linux.

KVM vs. incremental remote backups
by Nicolas Kovacs 04 Apr '21

04 Apr '21

Hi, Up until recently I've hosted all my stuff (web & mail) on a handful of bare metal servers. Web applications (WordPress, OwnCloud, Dolibarr, GEPI, Roundcube) as well as mail and a few other things were hosted mostly on one big machine. Backups for this setup were done using Rsnapshot, a nifty utility that combines Rsync over SSH and hard links to make incremental backups. This approach has become problematic, for several reasons. First, web applications have increasingly specific and sometimes mutually exclusive requirements. And second, last month I had a server crash, and even though I had backups for everything, this meant quite some offline time. So I've opted to go for KVM-based solutions, with everything split up over a series of KVM guests. I wrapped my head around KVM, played around with it (a lot) and now I'm more or less ready to go. One detail is nagging me though: backups. Let's say I have one VM that handles only DNS (base installation + BIND) and one other VM that handles mail (base installation + Postfix + Dovecot). Under the hood that's two QCOW2 images stored in /var/lib/libvirt/images. With the old "bare metal" approach I could perform remote backups using Rsync, so only the difference between two backups would get transferred over the network. Now with KVM images it looks like every day I have to transfer the whole image again. As soon as some images have lots of data on them (say, 100 GB for a small OwnCloud server), this quickly becomes unmanageable. I googled around quite some time for "KVM backup best practices" and was a bit puzzled to find many folks asking the same question and no real answer, at least not without having to jump through burning loops. Any suggestions ?

SELINUX blocks procmail from executing perl script without logging
by Radu Radutiu 04 Apr '21

04 Apr '21

Hi, I'm upgrading our request tracker from Centos 7 to 8 and found some unexpected SELINUX issues with procmail. Even after I create a policy which allows all denied operations, procmail is still not allowed to run a perl script (in my case rt-mailgate). I get the following error in the procmail log: "Can't open perl script "/opt/rt5/bin/rt-mailgate": Permission denied" but I have no denied audit entry in /var/log/audit/audit.log. If I set selinux to permissive, everything works fine. Any idea how to debug this? Best regards, Radu

Migrating to nvme and expand
by Jerry Geis 02 Apr '21

02 Apr '21

I have older SATA disks (2 of them size 2T) in a software raid config running CentOS 7. /dev/md127 is / and xfs /dev/sda2 is swap /dev/md126 is /home and xfs I desire to get a new (single) NVME 4T disk. What is the correct way to copy the software raid to a single "new" NVME disk ? then expand the /home file system to All the remaining space? Thanks, Jerry
