Subject: Palo Alto VM-Series Firewall is based on CentOS Linux Good day from Singapore, I have discovered that Palo Alto VM-Series Firewall is based on CentOS Linux. How can I find out what version of CentOS Linux is being used? I am interested in the Linux kernel version being used as well.

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"

What is the reason for xxhash removal from C10S? (CS-2476)
by Fredrik Nyström 06 Sep '24

06 Sep '24

Reason I'm asking is rsync. In a high bandwidth environment rsync is generally ~3 times slower and consumes more than 3 times as much CPU with md5 compared to xxhash. Kind Regards, -- Fredrik Nyström, NSC

Where can I find the archive kernel rpm packages for Centos stream 9
by wj523＠126.com 05 Sep '24

05 Sep '24

I can only find the Centos stream 9 kernel rpm package from kernel-5.14.0-479.el9.x86_64.rpm to kernel-5.14.0-503.el9.x86_64.rpm, which were created in two months period? Where is the kernel which is older, such as 5.14.0-419.el9.x86_64, 5.14.0-457.el9.x86_64. Do we have a archive site or something like centos-vault to find the old centos 9 stream rpm packages? Thank you.

Problem installing c10s
by Orion Poplawski 16 Aug '24

16 Aug '24

I'm attempting a kickstart install of c10s and I'm seeing it try to download the following URL: https://infrastructure.fedoraproject.org/repo/centos/centos-10/AppStream/x8… which fails due to being behind a proxy. This URL is not any of the repo URLs that I specified in my kickstart file. What's up here? -- Orion Poplawski he/him/his - surely the least important thing about me Manager of IT Systems 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/

CentOS 7 Installer Dual Stack via Kernel Params
by fetch＠posteo.nl 02 Aug '24

02 Aug '24

Hi all, I know I'm a bit late to ask this, but did the CentOS 7 installer kernel (here now https://vault.centos.org/7.9.2009/os/x86_64/images/pxeboot/) ever support setting an IPv4 AND an IPv6 address on the same interface? I've done some testing in a VM where setting EITHER IPv4 OR IPv6 works, but not both on the same interface, but is it possible to have dual stack settings applied to one interface via the kernel parameters? Assume that I have no ability to have a kickstart file locally, otherwise this could be worked around :/ Thanks
