Problems with CentOS 8 kickstart

Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file. Then I see the following message "kickstart install Started cancel waiting for multipath siblings for nvme0n1" This is what I have in the kickstart file # Clear the Master Boot Record zerombr # Partition clearing information clearpart --all --initlabel autopart --nohome --type=lvm --fstype=xfs ================ When I install from a USB drive it works OK and I have the following in /dev/disk/by-id lrwxrwxrwx. 1 root root 13 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810 -> ../../nvme0n1 lrwxrwxrwx. 1 root root 13 Jul 5 10:28 nvme-eui.002538b11102f46d -> ../../nvme0n1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 lvm-pv-uuid-5Dg4mg-saHa-hJJ6-n5a8-MxBS-gdFi-5jPoNn -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part2 UNG_MZVL2512HCJQ-0-> ../../nvme0n1p2 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part2 -> ../../nvme0n1p2 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part2 -> ../../nvme0n1p2 drwxr-xr-x. 2 root root 400 Jul 5 10:28 . lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkKtEdtLjwJQyIdxJcSvPv8TEAjwYGMv6yU -> ../../dm-0 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkKAooqrczySYJyiHvUAUji9oScPN2cVi7J -> ../../dm-1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-swap -> ../../dm-1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-root -> ../../dm-0 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkK5HZXbR2ow5xKGuD7jVe4UPzZm2qRLLXI -> ../../dm-2 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-home -> ../../dm-2 It's looks like that I am not doing the disk drive stuff in the config file correctly. -- Gerard Hooton.

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
by Yannis Milios 02 Feb '25

02 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"

Installing mdadm and C7 on new computer
by H 20 Oct '22

20 Oct '22

I have a new computer with 2 x 2TB SSDs where I wanted to install C7 and use mdadm for RAID1 configuration and encrypting the /home partition. On the net I found https://tuxfixer.com/centos-7-installation-with-lvm-raid-1-mirroring/ which I adopted slightly with respect to partition sizes, using RAID1 for /boot and /root as well and added the /home partition with RAID1 and chose to have /home encrypted. Is there an "official/recommended/suggested" page for installing C7 and using mdadm for RAID1 in combination with LUKS encryption? As far as I can tell things seem right but would like to check before proceeding to install lots of other software. Thanks.

OT:: Multiple PHP versions
by TE Dukes 22 Aug '22

22 Aug '22

Hello, Been trying to get multiple versions of PHP on a CentOS 7 machine, off and on for the past couple months. I have followed 5 or 6 different howtos but none work. They are very similar and they seems to be done on a fresh install as most do an apache install is the steps. I setup two virtualhosts one for PHP5.6 and one for PHP 7.4. When I create a file with phpinfo, it reports back 5.6.xxx on both sites. So, I'm wondering if I need to remove the existing PHP version that is included with CentOS? Any suggestions or a better way to do this? TIA

Raspberry Pi 4 and C++ 17
by Will 30 Apr '22

30 Apr '22

Hi, I have a program I want to run on a Raspberry PI 4 that was written on an x86_64 architecture. So I downloaded the Raspberry PI image of CentOS 7 and now I'm on armv7hl. Unfortunately, there doesn't appear to be any devtools for arm at all. Is there an easy(ish) way to get c++ 17 this architecture? Thank you! --- Will

Where can I find more information on the recent update to the 4.18.0-373 kernel
by Kay Schenk 29 Apr '22

29 Apr '22

Hello folks -- Is there any write up for the most recent update to kernel 4.18.0-373 specifically with respect to sound setup or anything really? I had been using an "alpha" driver for my Intel sound that was appended to my boot line up until this latest. This not only did not work but caused continual hangs. Edited the 4.18.0-373 kernel line and things got somewhat better...but....this version is loading A LOT of modules and do I really need them, etc. I am going through a lot of grief with this recent upgrade. Thanks for any help... -- Kay

Kernel rebuild failling on Centos 7: missing libbpf-devel and dwarves rpm too old

Hi, I'm trying to rebuild the kernel specifically on Centos7 from src.rpm but some packages are missing or too old. I managed to get them and compile on Centos8 though. Any advice? # yumdownloader --source kernel.src # rpm -ivh ./kernel-4.18.0-348.20.1.el7.src.rpm # rpmbuild -bb --target=`uname -m` ~/rpmbuild/SPECS/kernel.spec Building target platforms: x86_64 Building for target x86_64 error: Failed build dependencies: libbpf-devel is needed by kernel-4.18.0-348.20.1.el7.x86_64 rpm < 4.13.0.1-19 conflicts with kernel-4.18.0-348.20.1.el7.x86_64 dwarves < 1.13 conflicts with kernel-4.18.0-348.20.1.el7.x86_64 # rpm -q dwarves dwarves-1.10-1.el7.x86_64 # rpm -q rpm rpm-4.11.3-48.el7_9.x86_64 # yum search libbpf-devel Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: de.mirrors.clouvider.net * centos-sclo-rh: ftp.tu-chemnitz.de * centos-sclo-sclo: centos.mirrors.psw.services * epel: ftp.uni-kl.de * extras: mirror.imt-systems.com * updates: centos.mirror.iphh.net Warning: No matches found for: libbpf-devel No matches found # yum info rpm Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: de.mirrors.clouvider.net * centos-sclo-rh: ftp.tu-chemnitz.de * centos-sclo-sclo: mirror.softaculous.com * epel: mirror.nextlayer.at * extras: mirror.imt-systems.com * updates: centos.mirror.iphh.net Installed Packages Name : rpm Arch : x86_64 Version : 4.11.3 Release : 48.el7_9 Size : 2.5 M Repo : installed >From repo : updates Summary : The RPM package management system URL : http://www.rpm.org/ License : GPLv2+ Description : The RPM Package Manager (RPM) is a powerful command line driven : package management system capable of installing, uninstalling, : verifying, querying, and updating software packages.
