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"

Re: [CentOS] upg. CentOS 7.5 to 7.6: unable to mount smb shares - samba NT domain member using ldap

If you're using a real NT4 domain, then you shouldn't need a passdb backend at all. If you're not in an NT4 domain, then you should set "security = USER". The man page for smb.conf notes "This mode will only work correctly if net(8) has been used to add this machine into a Windows NT Domain." Did you add this host to a Windows NT domain, using "net join ..."?

CentOS 7.6 1810 vs. VirtualBox : bug with keyboard layout selection
by Nicolas Kovacs 20 Jan '20

20 Jan '20

Hi, I'm currently working on my next Linux book, which will be an elementary course about CentOS administration. I'm using VirtualBox for all the installer screenshots. Since CentOS has recently been upgraded to version 7.6, I thought I might as well base all book references on this version. So I downloaded the 7.6 1810 minimal ISO and started a fresh installation in VirtualBox. I'm using a Swiss French keyboard layout (ch-fr or fr_CH-latin1), so one of the first things I do in the installer is replace the default French AZERTY keyboard (since I use the french language) by a swiss french QWERTZ layout. Now when I reach this dialog in the installer and try do define my new layout, the slider in the selection window doesn't appear, and clicking on any of the first layouts doesn't do anything, so I'm basically stuck there. I'm running OpenSUSE Leap 15.0 KDE on my workstation, so I tried the same thing with the previous CentOS 7.5 1804 minimal ISO, and the keyboard selection dialog works perfectly. So my intuition would tell me that there's a nasty bug in the CentOS 7.6 installer. Maybe it went unnoticed, since most folks stick to the default keyboard layout selected in their language. Any suggestions ?

CentOS 7 as a Fibre Channel SAN Target
by Steffan A. Cline 02 Jan '20

02 Jan '20

For quite some time I’ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It’s time for me to replace my hardware and I have a new R720XD that I’d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I’m doing virtualization and this will allow me to have failover from one node to the other since they’ll all be sharing the same export rather than me simply backing up to the FreeNAS server the way I am now. Does anyone know of any really good current articles that explain how to set up CentOS 7 as the target in such a configuration and also setting up CLVMd so they can all share an export over Fibre Channel from CentOS 7?

UEFI and PXE
by isdtor 25 Oct '19

25 Oct '19

We have a working PXE setup. I've tried to adapt it to UEFI as per RHEL6 manual, but the client won't boot. Strangely, tcpdump shows that the client tries to download all files via tftp from the dhcp server rather than the tftp server (they are different). next-server is pointing to the tftp server. Any clues?

/boot partition too small
by KM 02 Oct '19

02 Oct '19

First off - let me say I am not an administrator. I need to know if there is an easy way to increase my /boot partition. When I installed CentOS 6 after running 5, it was my oversight not to increase the /boot size. it's too small and I can't do yum updates. if it's not easy to actually increase it, is it safe to take a chunk in my root filesystem (like /new.boot or something) and just mount it as /boot from now on so it uses the space or is that not a good idea? I am sure I could easily copy the rpms/kernel stuff over to it and then unmounts the real /boot and mount this new area as /boot. Can you administrators let me know what you think of all this? Thanks in advance. KM

CentOS 7 hibernation laptop
by H 10 Jul '19

10 Jul '19

I have a recent Dell Inspiron laptop on which I installed CentOS 7. I have, however, failed somewhere since I do not have a hibernate option when shutting down, only a suspend option. I believe I created the necessary hibernation partition large enough for the RAM the machine has, 16 Gb if I remember correctly. How do I identify where the problem lies?

raid 5 install
by Nikos Gatsis - Qbit 02 Jul '19

02 Jul '19

Hello list. The next days we are going to install Centos 7 on a new server, with 4*3Tb sata hdd as raid-5. We will use the graphical interface to install and set up raid. Do I have to consider anything before installation, because the disks are very large? Does the graphical use the parted to set/format the raid? I hope the above make sense. Thank you in advance.

iptables - how to block established connections with fail2ban?

28 Jun '19

I am working to a CentOS 6 server with nonstandard iptables system without rule for ACCEPT ESTABLISHED connections. All tables and chains empty (flush by legacy custom script) so only filter/INPUT chain has rules (also fail2ban chain): Chain INPUT (policy ACCEPT) target prot opt source destination f2b-postfix tcp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 192.168.0.0/16 0.0.0.0/0 ACCEPT all -- 127.0.0.0/8 0.0.0.0/0 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:25 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:443 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:587 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:993 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:995 DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp flags:0x17/0x02 Chain f2b-postfix (1 references) target prot opt source destination REJECT all -- 200.23.235.30 0.0.0.0/0 reject-with icmp-port-unreachable REJECT all -- 177.11.167.57 0.0.0.0/0 reject-with icmp-port-unreachable RETURN all -- 0.0.0.0/0 0.0.0.0/0 When fail2ban block a IP address, established connections are allowed to continue, but with no rule to accept established connections how is that possible?

Replacing kernel-headers with custom compiled version (from kernel.org) - safe?
by Bagas Sanjaya 27 Jun '19

27 Jun '19

Hello CentOS users, Currently I have compiled kernel version 4.19.37, which the source is from kernel.org. I compiled the kernel by following steps: - get the kernel tarball and unpack it - install prerequisties as described in https://wiki.centos.org/HowTos/Custom_Kernel (in addition bc and openssl-devel) - copy the kernel configuration: $ cp /boot/config-3.10.0-957.21.3.el7.x86_64 ~/linux-4.19.37/.config - create configuration: $ cd ~/linux-4.19.37 $ make olddefconfig $ make nconfig - compile and create RPM package: $ make vmlinux $ make modules $ make rpm-pkg - install kernel RPM: # yum install ~/rpmbuild/RPMS/x86_64/kernel-*.rpm However, in the last step (installing kernel RPM), I got following notice: ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: kernel x86_64 4.19.37_sentinel_custom-1 /kernel-4.19.37_sentinel_custom-1.x86_64 209 M kernel-devel x86_64 4.19.37_sentinel_custom-1 /kernel-devel-4.19.37_sentinel_custom-1.x86_64 817 M kernel-headers x86_64 4.19.37_sentinel_custom-1 /kernel-headers-4.19.37_sentinel_custom-1.x86_64 4.6 M replacing kernel-headers.x86_64 3.10.0-957.21.3.el7 Transaction Summary ================================================================================ Install 3 Packages There, the compiled kernel-headers package (4.19.37_sentinel_custom-1) is about to replace stock version (3.10.0-957.21.3.el7). Is it safe to continue installing from compiled RPM package above, or install kernel manually? Regards, Bagas

OK, I recently ugraded to the current ESR release of Firefox for CentOS 6. And I am having problems with the user interface (basically it has become hard [for me] to use).

About PCYNLITX project and its innovations ( for C+++ multi-threading )
by Erkam Murat Bozkurt 27 Jun '19

27 Jun '19

Previously, I have presented my project to you. The current name of my project is PCYNLITX. PCYNLITX platform offers completely new programming technology which can be named as Programmable Meta-Programming System and PCYNLITX platform is just a particular application of this new programming methodology. Basically, PCYNLITX is an intelligent integrated development environment ( IDE ) which can produce an application-specific multi-threading library based on your needs and assists you in multi-thread software development process. PCYNLITX is not a multi-threading library. Instead, it is a multi-threading library generator. You can find out very comprehensive documentation about pcynlitx project from both project web site and source code repository. The addresses of the project web page and source code repository are given in below links. www.pcynlitx.tech https://sourceforge.net/projects/pcynlitx The outcome of the PCYNLITX platform acts as an autonomous thread management system provides deterministic scheduling of the threads. You can control the thread with the numbers given by you and determine the relation of the threads. In other words, different from the other multi-threading tools, you can directly schedule the threads independently from the operating system. The scientific journal of the project is under review on IEEE Transactions on Software Engineering. Currently, the PCYNLITX platform only works on Linux based operating systems and the other versions ( Windows and McOSx ) are under development. The License of the PCYNLITX platform is GNU GPLv3 Free Software License. You can find out many other documents including scientific introduction of the project (“Technical Introduction” ), code examples and GUI tutorial form the project web sites. You can also find out a documents introducing std::thread programming, pthread programming and OpenMP programming on the web sites. I am always waiting your valuable comments and contributions. Thanks and best regards. Erkam Murat Bozkurt M.Sc in Control Systems

mplayer
by Chris Olson 25 Jun '19

25 Jun '19

We recently installed CentOS 7 from DVD. Our install selection was the GNOME desktop option. yum update yielded about 465 megabytes of updates all of which were successful with no warnings. The multi media option was not chosen because KDE was listed. GNOME was not apparent in the software list for the multi media workstation install. Google searches led us to instructions for installing mplayer. The repo update appears to be successful as indicated below. Dependency resolution at the time of mplayer installation yielded twelve errors. Are there other packages that could be installed prior to another attempt at mplayer installation that might provide the missing items? Might these errors have been avoided by choosing the multi media workstation install?

Disk Performance Issue
by Chris Olson 25 Jun '19

25 Jun '19

We have a very old Dell desk top machine that has been running CentOS 6 for the past five years. It received a new, 1 TB disk and additional memory before the OS installation. It has been the primary Linux machine in our smallest and most remote field office. It has been updated at least once a week and has all current dates installed. Boot-up this morning lasted about six times as long as usual. Disk access, as indicated by the disk activity light, is almost continuous and for extended periods of time when ever something is done that requires the disk. Everything observed happens whether or not the machine is connected to our network. All of our files appear to be accessible if one is patient. One theory put forward is that some application is running that uses up CPU and disk bandwidth. Another theory is that thereare disk errors, mostly corrected by EDCS features. We do not see any rogue applications and error logs show no disk issues. This is a mysterious issue that we hope to circumvent by putting a new disk and installing CentOS 7 from DVD. Our hope is that the current disk can be mounted externally on the new CentOS system using a USB to SATA adapter and that data can be moved off of the old disk. Advice regarding this issue and any possible diagnostic methods will be greatly appreciated. df -k output: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_delle520-lv_root 51475068 12110896 36742732 25% / tmpfs 1928152 176 1927976 1% /dev/shm /dev/sda1 487652 211073 250979 46% /boot /dev/mapper/vg_delle520-lv_home 905124888 246856176 612284356 29% /home +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Issue with dvd/cdrom drive
by doug schmidt 24 Jun '19

24 Jun '19

Hi, I'm having an issue with my Thinkpad P70 laptop/workstation. This system is a dual boot, windows 10 pro and centos 7. I have not needed to use the cdrom until now, however the system does not see it in /dev. I know the cdrom works as I can use it in windows 10 and when initially installing centos 7, I installed from dvd media. I'm not sure what to check. I do not see anything related in dmesg. I have previous copies of kernel on the system and tried booting with 3.10.0-957.el7.x86_64 but I'm seeing the same. ---------- # uname -r 3.10.0-957.21.3.el7.x86_64 # lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers (rev 07) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics P530 (rev 06) 00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31) 00:14.2 Signal processing controller: Intel Corporation 100 Series/C230 Series Chipset Family Thermal Subsystem (rev 31) 00:16.0 Communication controller: Intel Corporation 100 Series/C230 Series Chipset Family MEI Controller #1 (rev 31) 00:16.3 Serial controller: Intel Corporation 100 Series/C230 Series Chipset Family KT Redirection (rev 31) 00:17.0 RAID bus controller: Intel Corporation SATA Controller [RAID mode] (rev 31) 00:1c.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #1 (rev f1) 00:1c.2 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #3 (rev f1) 00:1c.4 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #5 (rev f1) 00:1d.0 PCI bridge: Intel Corporation 100 Series/C230 Series Chipset Family PCI Express Root Port #13 (rev f1) 00:1f.0 ISA bridge: Intel Corporation CM236 Chipset LPC/eSPI Controller (rev 31) 00:1f.2 Memory controller: Intel Corporation 100 Series/C230 Series Chipset Family Power Management Controller (rev 31) 00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31) 00:1f.4 SMBus: Intel Corporation 100 Series/C230 Series Chipset Family SMBus (rev 31) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM (rev 31) 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M600M] (rev a2) 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) 05:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:00.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:01.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:02.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 06:04.0 PCI bridge: Intel Corporation DSL6540 Thunderbolt 3 Bridge [Alpine Ridge 4C 2015] 07:00.0 System peripheral: Intel Corporation DSL6540 Thunderbolt 3 NHI [Alpine Ridge 4C 2015] (rev ff) 3b:00.0 USB controller: Intel Corporation DSL6540 USB 3.1 Controller [Alpine Ridge] 70:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Vulnerabilities to bind-libs bind-utils - possible to remove these on webservers
by Peda, Allan (NYC-GIS) 24 Jun '19

24 Jun '19

I think the subject says it all. We don't run named. It seems there are chronic issues with bind. Can these packages be removed? We locally authenticate. I see this: Removing for dependencies: bind-utils ipa-client sssd sssd-ad sssd-ipa We shouldn't need any of that with local authentication (/etc passwd and /etc/shadow) right?

Danger, Will Robinson: Visual Studio with CentOS
by mark 24 Jun '19

24 Jun '19

Had a manager come by, to tell me one server seemed to be running slow, but nothing much was on it. Well, it turned out to be a user who was using Visual Studio on his Win10 laptop to edit files on the server. And VS used sftp to get to the files. Yeah, about that: ssh in about 4 times a second.... Things sped up with he killed that. Be warned. mark
