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?

The workstations with E5-2609, E5-2650 or E5-2630 are not affected - all of them run qemu-kvm VM under kernel-3.10.0-1160.80.1.el7.x86_64 without problems. Any ideas?

CentOS 7: Missing Thunderbird Updates
by Chris Schanzle 21 Nov '22

21 Nov '22

Hi, Looks like CentOS 7 hasn't shipped Thunderbird updates for a while. The latest I see in repos is: Sep 1 15:22 thunderbird-91.13.0-1.el7.centos.x86_64.rpm Perusing through the RHEL announcements, that was from the RHSA-2022:6169-01 on 2022-08-24. Seems none of the 102.x versions have shipped: 2022-09-26 RHSA-2022:6710-01 thunderbird-102.3.0-3.el7_9.x86_64.rpm 2022-10-18 RHSA-2022:6998-01 thunderbird-102.3.0-4.el7_9.x86_64.rpm 2022-10-25 RHSA-2022:7184-01 thunderbird-102.4.0-1.el7_9.x86_64.rpm And for completeness, just announced today: 2022-11-21 RHSA-2022:8555-01 thunderbird-102.5.0-2.el7_9.x86_64.rpm Thanks in advance for efforts to find and clear the blockage!

CentOS 9 Stream mirrorlist url's
by Jos Vos 19 Nov '22

19 Nov '22

Hi, I'm trying to port a CentOS 8 Stream kickstart file to CentOS 9 Stream, but I cannot find what repo mirrorlist url's I now have to use. For CentOS 8 Stream I had: repo --name=centos-baseos --mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=BaseOS repo --name=centos-appstream --mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream repo --name=centos-extras --mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=Extras repo --name=centos-powertools --mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=PowerTools Just replacing the 8 by 9 does not work, as those url's produce an "Invalid release/repo/arch combination" error. UNfortunately I couldn't find info about this on the CentOS site so far.

Hi! So, i have nvme which reports the following (lsblk -t): NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED RQ-SIZE RA WSAME nvme0n1 0 131072 131072 32768 4096 0 none 1023 256 0B the nvme ns is formated with LBA=1 (4k) option (which is the second option after 512) but both lsblk and parted report sector size logical/physical as 4k/32k The question is : what block size should i use (is optimal) for file-system? Should i try a 32k blocksize? Thanks a lot! Adrian

Trouble with kernel-3.10.0-1160.80.1.el7.x86_64
by Orion Poplawski 10 Nov '22

Is anyone else experiencing trouble with kernel-3.10.0-1160.80.1.el7.x86_64? I'm seeing a kernel panics in the kvm module on one of our VM hosts with it. I did notice a new libvirt update as well, but it seems to work fine with the older kernel (.76.1). -- Orion Poplawski IT Systems Manager 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

set default permission to deployuser:deployuser for nfs common mount point /mnt/test
by Kaushal Shriyan 09 Nov '22

09 Nov '22

Hi, I am running two GCP GCE VM instances running CentOS Linux release 7.9.2009 (Core) behind https load balancer. I am using https://cloud.google.com/filestore#documentation to mount the nfs server common mount point to both client servers. #mount 10.0.0.2:/vol1 /mnt/test I did chown -Rc deployuser:deployuser (user:group) /mnt/test. When the php code uploads any file to the /mnt/test folder, the file permission is owned by php-fpm:php-fpm (user:group) Please guide and let me know how to set it to the default permissions of deployuser:deployuser (user:group) for all files and folders created in nfs server common point /mnt/test. Thanks in advance. Best Regards, Kaushal
