Memory vs. Display Card
by Rick 28 Oct '25

28 Oct '25

Since memory has become quite cheap lately I decided to move from 2 GB to 6. When I installed the memory every thing was fine until I went to run level 5. At that point the screen turned to garbage and the system froze. Is there a way to fix this so I can use the memory I bought? Do I need a new display card?

SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
by Yannis Milios 01 Feb '25

01 Feb '25

Hello, I'm having a strange problem booting a new centos7 installation. Below some background on this. [I have attached the tech details at the bottom of this message] I started a new CentOS7 installation on a VM, so far all good, o/s boots fine. Then I decided to increase VM disk size (initially was 10G) to 13G. Powered off the VM, increased the vhd via the hypervisor, booted from CentOS livecd, selected "recover my centos installation". Then I used the following sequence of commands to make the new vhd size "visible" to the o/s ... - ran fdisk /dev/sda and deleted partition 2. (This is the LVM partition where the o/s is stored. The first partition is /boot [xfs] partition *non lvm*.) - created a new partition with same starting sector as before deleting it, but a different ending sector (to reflect to the increased space). - set partition type to 8e (lvm), saved settings and exit. - ran pvresize and lvresize to make new space visible to the o/s.All good, I can see the space increase on 'lvdisplay centos/root'. - ran 'mount /dev/mapper/centos-root /mnt/root' to temporarily mount the o/s partition. - ran 'xfs_growfs /mnt/root' to resize the o/s fs to the new size. It was successful and I could actually chroot to the o/s and verify new disk size. - rebooted and tried to boot from hdd this time. Grub menu shows up and loads default kernel (3.10.0-862.9.1.el7.x86_64). - after initial kernel boot up process, booting continues to initrd and then it's where the problem starts... - looks like dracut has issues locating/enabling /dev/mapper/centos-root (lv) and as a result it cannot boot to the 'real' root fs (/). - while in dracut shell, I execute the following command sequence: 1. lvm lvchange -ay /dev/centos/root 2. lvm lvchange -ay /dev/centos/swap 3. ln -s /dev/mapper/centos-root /dev/root 4. exit ...and the o/s boots fine...so looks like the pv,vg,lv is detected properly while in initrd, but somehow dracut has difficulties enabling the root,swap LVs ? - While in o/s, I rebuild initrd by using: 'dracut -f -v -a lvm' Note, I have to use '-a lvm' as for some reason, if don't, the lvm utils (lvm,lvm_scan) are not being included to the initrd, not sure why this happens. After rebooting, same thing happens, I have to manually boot the system via dracut shell. I'm a bit stuck at this point, any clues what I'm doing wrong in here ? As I previously said, this is a new installation, so I could simply reinstall the whole thing, but I would rather try to find out some answer to why is this happening ... :-) [curiosity] Some additional details: ================== I've attached /run/initramfs/rdsosreport.txt file [generated while in inird] here: https://privatebin.net/?fdc4052c0c402884#gdB/QYR3IeR55SxUbjfrkZPQfJ7jMxiUxq… o/s ver=CentOS Linux release 7.5.1804 (Core) [root@localhost ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 13G 0 disk ├─sda1 8:1 0 500M 0 part /boot └─sda2 8:2 0 12.5G 0 part ├─centos-root 253:0 0 11.5G 0 lvm / └─centos-swap 253:1 0 1G 0 lvm [SWAP] [root@localhost ~]# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rd.shell rhgb" GRUB_DISABLE_RECOVERY="true"

NFS Share fails to mount at boot time
by Felix Natter 15 Jan '22

15 Jan '22

hello fellow CentOS Users, on Scientific Linux 7 (_very_ similar to CentOS7), I get this when trying to mount NFS Shares (exported from Synology NAS) automatically at boot time: [root@HOST ~]# journalctl -b 0 | grep NAS[20] Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS0... Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS2... Jul 01 13:32:09 HOST systemd[1]: mnt-NAS0.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS0. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS0.mount entered failed state. Jul 01 13:32:09 HOST systemd[1]: mnt-NAS2.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS2. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS2.mount entered failed state. I read that enabling NetworkManager-wait-online.service can mitigate that, but it's already enabled: [root@HOST ~]# systemctl list-unit-files|grep wait chrony-wait.service disabled NetworkManager-wait-online.service enabled plymouth-quit-wait.service disabled /mnt/NAS2 is defined in /etc/fstab (/mnt/NAS0 is mounted analogously): NAS2HOST:/volume1/export/ /mnt/NAS2 nfs rw,vers=3,soft,bg,intr 0 0 This does not always occur, and it seems to be a race condition, because it did not occur a few months ago, before we moved offices (when only the networking changed slightly). Of course, once the computer is booted, I can always mount the shares without problems. Does someone have an idea? Many Thanks and Best Regards, -- Felix Natter

Microsoft Teams on CentOS 7. Does the latest version work?
by Toralf Lund 03 Dec '21

03 Dec '21

Does anyone else run Microsoft Teams on CentOS 7? I've used it for a while now, and it's generally worked reasonably well. However, after upgrading to the latest version from the Microsoft repos, it doesn't start up properly. Processes start and remain active until I give up and kill them, but I can't see a window or a tray icon or anything. Has anyone else seen this? Is there anything I can do to make the GUI appear? This is not a big deal as everything just works fine if I revert to the previous release, but it would be interesting to know if this is a general problem with the software, or I have some weird issue with my system. The release that doesn't work is 1.4.00.13653. The one that does is 1.4.00.7556. - Toralf

MATE 1.20 test build for CentOS 7 available
by Greg Bailey 14 Oct '21

14 Oct '21

Hi everyone, There's been discussions in the past about updating MATE RPMs in EPEL-7: https://bugzilla.redhat.com/show_bug.cgi?id=1436260 https://lists.centos.org/pipermail/centos/2019-August/173154.html (and lots of others...) As a proof-of-concept, I've written some scripts that clone specific commits from the Fedora master branches, and then runs a tool to re-apply RPM scriptlets that are required by EL7 but removed from the Fedora .spec files. The scripts are available at: https://github.com/gebailey/mate-rpms/tree/master/1.20/el7 There's also instructions there if you want to try upgrading to MATE 1.20 w/o rebuilding them yourself. If these packages work for others, perhaps we can revisit the idea of updating the epel7 branches of the Fedora git repos and submitting an official update. There's nothing here (yet) about building MATE 1.22 (which might require a newer gcc for EL7), or building anything on CentOS 8, but thought the CentOS 7 users might find this helpful. -Greg

GNOME UI / gnome-shell broken
by Felix Natter 11 Sep '21

11 Sep '21

hello CentOS7 users, I have an up-to-date Scientific Linux 7 (_very_ similar to CentOS7). The problem is that if one user (we have central homes) logs into any machine, we only see a desktop with icons, but no window decorations or top/bottom bars ("panels") (for both gnome-classic and gnome3). I can fix the window decorations by running "metacity --replace", but the other problem remains. I tried to remove .gnome, .gnome2, .gconf, .metacity, .cache, .dbus, .dmrc. I noticed that when starting "gnome-shell --replace" from a terminal, I get "Failed to migrate monitor configuration for ... Empty Configuration", and when running gnome-control-center, the option "Displays" shows "Could not get screen information" and the console shows: 'Name "org.gnome.Mutter.DisplayConfig" does not exist'. This happens both when logging in physically and when logging in virtually using VNC. How can I fix this? Do I need to reset more of GNOME's config? Many Thanks and Best Regards!

Mirror problem
by isdtor 05 Sep '21

05 Sep '21

Updating my local mirror, I noticed x86_64/Packages/exiv2-0.27.0-4.el7_8.src.rpm x86_64/Packages/firefox-78.13.0-2.el7.centos.src.rpm x86_64/Packages/thunderbird-78.13.0-1.el7.centos.src.rpm which seem have been pushed into the wrong repo by accident. Confirmed by checking another random mirror in the US from https://www.centos.org/download/mirrors/.

Upgrading (?) from legacy boot to UEFI
by Rob Kampen 30 Aug '21

30 Aug '21

After three days of effort I have failed to find a way of shifting a server from legacy boot to UEFI boot. I have made my way through the 400+ pages of RH installation manual for EL7, plus their similarly large system administrators manual. Dozens of pages searched via google and yet none of the layouts for the /boot and /boot/efi have worked in my case. System is a Lenovo 3650 M5 with UEFI bios. Due to RH / CentOS design my initial install onto the two 600GB HDD partitioned these using MBR and legacy boot. I have just obtained two SAS SSD drives of 3.8TB and thus MBR is no longer an option. I have successfully migrated all the system and data from the HDD to the SSD, complete with GPT and RAID1 and all works as expected - except the HDD was still needed to boot the system. That's when the fun / agony started. Each system reboot is almost five minutes just to get to the <F1> for system setup option. Thus testing is a very slow process. I am now at the point where I have a "bios boot" partition (1024K type ef02) as the first partition on each GPT partitioned SSD and have grub2-install onto the drives the bios boot junk needed for legacy boot. Thus I can at least legacy boot from one of the SSD and all comes up as expected. (no idea yet why it only works from one of the SSD and not the other). Unfortunately the server is remote and the CentOS7 USB device I left plugged into the machine refuses to boot from UEFI mode. Thus a rescue mode boot has not been possible. I have two 300MB partitions, one on each SSD suitably formatted (type ef00 and vfat) and set up with the files as follows: -rwx------. 1 root root 134 Aug 1 2020 BOOT.CSV -rwx------. 1 root root 134 Aug 1 2020 BOOTX64.CSV drwx------. 2 root root 4096 Aug 27 16:22 fonts -rwx------. 1 root root 6597 Aug 27 21:33 grub.cfg -rwx------. 1 root root 1024 Aug 26 23:22 grubenv -rwx------. 1 root root 1122120 Mar 17 07:24 grubx64.efi -rwx------. 1 root root 19378672 Aug 26 20:29 initramfs-3.10.0-1160.36.2.el7.x86_64.img -rwx------. 1 root root 1154640 Aug 1 2020 mmx64.efi -rwx------. 1 root root 1154640 Aug 1 2020 MokManager.efi -rwx------. 1 root root 1243864 Aug 1 2020 shim.efi -rwx------. 1 root root 1237824 Aug 1 2020 shimx64-centos.efi -rwx------. 1 root root 1243864 Aug 1 2020 shimx64.efi -rwx------. 1 root root 6777448 Aug 26 20:27 vmlinuz-3.10.0-1160.36.2.el7.x86_64.efi unfortunately grub2-mkconfig sets up the grub.cfg as for legacy boot because the /sys/firmware/efi does not exist, thanks to running from a legacy boot. I tried a few manual edits to the grub.cfg to deal with linux16 -> linuxefi and initrd16 -> initrdefi but to little avail. Can someone point me to what needs to happen for UEFI boot to work successfully. I am unsure what file I need to point the UEFI bios disk manager setup at, I have tried shim.efi and shimx84-centos.efi The message I get is that linux16 and initrd16 cannot find their files. The change to linuxefi and initrdefi also fail but the system reboot happens before I can see what flashes on screen. Is a USB based UEFI booted rescue mode the only way I can fix this? TIA for your pointers / suggestions.

Annoying shortcut

For at least this year, I'm finding that whether I'm in LibreOffice, or Thunderbird, or Firefox, if I do *something*, and I haven't identified what, backspace will delete the entire word, though I haven't hit ctrl-bkspc. In system settings, it should only be the ctrl-bkspc. Has anyone else seen this behavior? mark

The latest version of git for C7 is 1.8.3 and in SCL it's 2.18 although the repository claims 2.9 is also available. I am looking to upgrade to 2.23 since i need the --no-overlay option. Is anyone running this version (or later)? If so, from which repository? Thanks.

Minimising a CentOS installation
by Anand Buddhdev 21 Aug '21

21 Aug '21

Hi folks, After doing a minimal CentOS 8.4 installation, I found the following packages to be useful for a simple server, so I removed them: cronie-anacron (replaced with cronie-noanacron) alsa-firmware ivtv-firmware iwl*-firmware sssd-common (along with all packages that depended on it) What other things do folk usually remove to make their installation smaller? Regards, Anand

Re: [CentOS] A Blast from the past
by Mark Woolfson 18 Aug '21

18 Aug '21

Hello, Can you please help with an interesting problem. I have an Intel Haswell based processor with CentOS 7.0 with an early kernel booting and running perfectly. I changed the processor to an Ice Lake and I get the problem below when I boot the working Haswell disk. The boot process hangs almost immediately and when I remove the 'quiet' boot parameter I see that it hangs randomly, usually with a high CPU number, when SMPBOOT is starting up the cores. The only solution I have found is to boot with the 'nr_cpus=8 (could be any low number), update to the latest kernel then reboot with the 'nr_cpus=8' parameter removed. On examination there are no problems with CentOS 7.4 and above but there are with CentOS 7.3 and below. Mark -- This email has been checked for viruses by AVG. https://www.avg.com

centos 8 stream / last yum update / VirtualBox 6.1.26
by Mathy Froeyen 06 Aug '21

06 Aug '21

Hi all Till this morning, I ran Windows 10 client on VirtualBox 6.1.24 on host Centos 8 stream kernel 4.18.0-315.el8 without problem (desktop). I took the risk to do a "yum update" and as well as the kernel as the VirtualBox were updated: kernel going from 4.18.0-315.el8 to 4.18.0-326.el8 VirtualBox going from 6.1.24 to 6.1.26 But yum complained already : ...

I also tried to install VirtualBox 6.0 and 5.2 with the same kind of error in yum. I rebooted then the computer and started a previous kernel 4.18.0-310.el8 and reinstalled Virtualbox 6.1.26 now without those errors and it runs smooth as before. (Kernel 315 had the same vbox errors.) However, when I went back to kernel 4.18.0-326 and tried starting there VirtualBox 6.1.26 again, he complained with : ... Failed to open a session for the virtual machine Windows10. Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing '/sbin/vboxconfig' as root. ... (I tried that "/sbin/vboxconfig" but that tells me nonsense about registering because of EFI secure boot, but I did not change anything in the BIOS.) or there is some conflict between the last kernels and VirtualBox? cheers mathy

Transition test report going from CentOS8 to Debian 10.
by Lamar Owen 06 Aug '21

06 Aug '21

Sorry for the length.... I'm posting this here since this particular transition has been mentioned on-list as one possibility for a path forward for current CentOS Linux users. AlmaLinux, the Developer Subscription RHEL, Rocky, CentOS Stream, Springdale, upgrading to full RHEL; all these are also possibilities, too, and all have different strengths and weaknesses. The transition to Debian has a lot of strengths, including a long track-record of support (even if the support time for a particular release is shorter), a fully-open development model with no 'corporate overlord' that I know of, a large set of supported packages, and a huge community of developers and users. For the CentOS user the main weakness is having to learn a few areas of difference in the way the system is setup and maintained; of course, if a ten-year 'stable' timeframe is really that important to you the lack of that is also a weakness. So, last week I transitioned, as a test of sorts, my working CentOS 8 main laptop to Debian 10. I kept a complete backup of the C8 install should I wish to go back to it, and installed Buster to a new mSATA SSD, but ported the two SATA drives (Dell Precision M6700 - has an mSATA slot plus two SATA bays) straight over after making full backups. I posted a pretty complete rundown on the scientific linux users mailing list, so I won't recap it all here. The bottom line was the the transition was not any more difficult, really, than moving from CentOS 7 to CentOS 8. The software versions in Buster are pretty close to what is in CentOS 8, although I have yet to need any third-party repository (PPA) for anything I've needed to install. All the packages I have worked with so far have worked fine with a little bit of massaging. These include commercial (and costly) software such as Harrison Consoles' Mixbus32C, Qoppa's PDFStudio2019 Professional, and others. So if you were to decide that this is the route for you to take, it does work and I found it to be not nearly as hard as I had thought it might be. If you install GNOME 3 you get GNOME 3; it feels pretty much the same as a non-Classic CentOS GNOME 3, just with a different set of extensions installed by default. That's on the workstation. On the server side, I'm evaluating Proxmox for the virtualization solution, and so far I'm finding it to be a pretty easy migration. I'm using the 'non-subscription' repository, so this is a no-cost option. Even getting the box registered to our EMC Clariion SAN was relatively easy; EMC provides the Unisphere Server Utility for Linux x64 in RPM form; the latest I have is "ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm" (which is fairly old, but I did say Clariion arrays, so they're pretty old, too). Debian has provided the 'alien' tool for some time; after installing alien, a simple 'alien -i ServerUtil-Linux-64-x86-en_US-1.0.55.1.0044-1.x86_64.rpm' installed the EMC RPM in the correct place. Proxmox already included everything that serverutilcli requires; on a plain Buster install I had to install dm-multipath and the device mapper libraries and tools before serverutilcli would find the arrays; but it ran just like it did on CentOS 8 (and 7). I haven't decided whether to stay on Debian or not; too early to tell. I have time to test and evaluate. My CentOS 7 installs aren't goin anywhere, though, at least until late 2023. And I've registered for a Developer subscription of RHEL so that I can properly evaluate that option, too. This is the beauty of open source: we have OPTIONS.

virt-manager and windows quest
by Jerry Geis 05 Aug '21

05 Aug '21

I am trying to get a windows guest on CentOS 7.9 to have more than 800x600 display. I started the Windows client, I downloaded Virtio 0.1.196.iso, went to the Device Manager, Display, right clicked - updated the driver - installed the qxldod driver, Rebooted. The Device Manager shows RedHat QXL Controller but I still only get 800x600 ghosted on Display Settings. Properties - shows "Windows has stopped this device as it reported a problem (Code 43)". What do I do with that ? This is the same error I had with I first tried VirtIO 0.1.185.iso Thanks, Jerry

hosts.deny, fail2ban etc.
by H 04 Aug '21

04 Aug '21

|Running CentOS 7. I was under the impression - seemingly mistaken - that by adding a rule to /etc/hosts.deny such as ALL: aaa.bbb.ccc.* would ban all attempts from that network segment to connect to the server, ie before fail2ban would (eventually) ban connection attempts. This, however, does not seem correct and I could use a pointer to correct my misunderstanding. How is hosts.deny used and what have I missed? Is it necessary to run: iptables -I INPUT -s aaa.bbb.ccc.0/24 -j DROP to drop incoming connection attempts from that subnet? Thank you! |

CentOS 8: two external network adapters, two ISPs - routing problems
by Konstantin Boyandin 02 Aug '21

02 Aug '21

Hello! Given: a CentOS 8-powered computer with three network adapters. eth0, eth2: external, connected to two different ISPs eth1: faces home network (intranet) The task: allow accessing certain internal services from either ISP. There are several services, I only mention SSH below. In the configs below: IP1: external IP at first ISP (ISP1), assigned to eth0 Gateway1: IP of gateway provided by ISP1 Network1,Netmask1: related to IP1 IP2: external IP at second ISP (ISP2), assigned to eth2 Gateway2: IP of gateway provided by ISP2 Network2,Netmask2: related to IP2 LocalSSHIP: IP in intranet (eth1) where SSH server is running Current configs follow. Routing tables: echo "200 isp1" >> /etc/iproute2/rt_tables echo "201 isp2" >> /etc/iproute2/rt_tables Routing policies: /etc/sysconfig/network-scripts/route-eth0 Network1 dev eth0 src IP1 table isp1 default via Gateway1 dev eth0 table isp1 /etc/sysconfig/network-scripts/route-eth2 Network2 dev eth2 src IP2 table isp2 default via Gateway2 dev eth2 table isp2 Routing rules: /etc/sysconfig/network-scripts/rule-eth0 from IP1/32 table isp1 /etc/sysconfig/network-scripts/rule-eth2 from IP2/32 table isp2 iptables snippets. External traffic forwarded to local SSH server from both interfaces: iptables -A PREROUTING -t nat -i eth0 -p tcp -d IP1 --dport 22 -j DNAT --to LocalSSHIP:22 iptables -A PREROUTING -t nat -i eth2 -p tcp -d IP2 --dport 22 -j DNAT --to LocalSSHIP:22 iptables -A FORWARD -p tcp -d LocalSSHIP --dport 22 -j ACCEPT eth0 is default gateway: $ ip route default via Gateway1 dev eth0 proto static metric 100 default via Gateway2 dev eth2 proto static metric 101 ... $ ip rule 0: from all lookup local 32764: from IP2 lookup isp2 32765: from IP1 lookup isp1 32766: from all lookup main 32767: from all lookup default SNAT is applied for the traffic originating from eth1: iptables -t nat -A POSTROUTING -i eth1 -o eth0 -j SNAT --to-source IP1 Current situation: - All services forwarded from eth0 are working normally. - All traffic originating from intranet passes out and back normally. - All the attempts to access services from eth2 time out. There are no obvious hints in /var/log/messages (such as complaints about "martian IPs"). I am somewhat at a loss here, all the pieces of advice would be very welcome. -- Sincerely, Konstantin Boyandin
