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"

Apache mpm itk
by Gionatan Danti 17 May '23

17 May '23

Hi all, the EPEL repository for CentOS7 contains httpd-itk, an apache module for running different vhosts under specific user/group ID. For RHEL8 I can find it only in 3rd party repos, while I misses it entirely for RHEL9. Is the module deprecated? Can it be re-included into EPEL? Regards. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti(a)assyoma.it - info(a)assyoma.it GPG public key ID: FF5F32A8

Installing mdadm and C7 on new computer
by H 19 Oct '22

19 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.

CentOS Stream 8: ISOs an Docker images
by Carel Combrink 20 Sep '22

20 Sep '22

Dear CentOS, Regarding the Docker images on https://quay.io/repository/centos/centos?tab=tags&tag=stream8: What are the plans or expectations about the tags uploaded there and the ISOs published to https://www.centos.org/download/ (or rather the mirrors)? For example: From a mirror for Centos 8 Stream the current ISO is "CentOS-Stream-8-x86_64-20220915-dvd1.iso" (dated 5 days ago). And in the docker repo the current one has a LAST MODIFIED time of 10 hours ago. Would it be possible to consider labeling the docker images to match the ISO that they correspond to (if they do correspond to some ISO)? For example have a "quay.io/centos/centos/stream8:20220915" image? Regards, Carel

Fedora EPEL vs Oracle EPEL
by Anand Buddhdev 08 Sep '22

08 Sep '22

Hi folks, Are there any Oracle Linux users here? What are you doing with EPEL? Do you use Fedora EPEL, or Oracle EPEL? What are your reasons for using one or the other? I am aware that these two repos are quite similar, but not identical. Regards, Anand

CentOS 9 Stream on Workstation with Ver. 1 x86_64 cpu
by Mike 05 Sep '22

05 Sep '22

Hello All, RHEL9 deprecated version 1 x86_64 cpus. My old testbench HP workstation has such a version 1 cpu. I've tested install of Rocky Linux 9 and CentOS9Stream but no go upon reboot after install -- kernel panic. Is there a way to recompile the kernel to handle the legacy cpu after install -- via some other live cd, perhaps? Due to the fact I can't reboot after install, I'm not able to build a kernel using the following: https://wiki.centos.org/HowTos/Custom_Kernel Sidenote: I'd also like to include support for btrfs too, but first things first. Thank you.
