setting kernel IP boot values
by Jerry Geis 02 Jul '20

02 Jul '20

Hi I found this information: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/ht… Specifically: Set the configuration using the ip option on the kernel command line: ip<client-IP-number>:[<server-id>]:<gateway-IP-number>:<netmask>:<client-hostname>:<interface>:{dhcp|dhcp6|auto6|on|any|none|off} dhcp - DHCP configuration dhpc6 - DHCP IPv6 configuration auto6 - automatic IPv6 configuration on, any - any protocol available in the kernel (default) none, off - no autoconfiguration, static network configuration For example: ip=192.168.180.120:192.168.180.100:192.168.180.1:255.255.255.0::enp1s0:off but I am confused. I desire to set IP boot values with DHCP and name of machine say jerry. so I would use ip=::::jerry.domain:eth0:dhcp Is this correct ? Jerry

How to Mirror CentOS8 repository in CentOS7 Server via reposync
by psuresh 02 Jul '20

02 Jul '20

Hi I'm running CentOS7 server as ImageServer and local repository server. And i need to mirror CentOS8 repository (http://mirror.centos.org/centos-8/8.1.1911/AppStream/x86_64/os/ ) in my CentOS7 Server. If i mirror CentOS8 repository using repo sync command in CentOS7 it did not properly mirror centos8 repository, due to that when i install package from CentOS8 client machine getting following error. No available modular metadata for modular package 'python3-lldb-8.0.1-1.module_el8.1.0+215+a01033fb.x86_64', it cannot be installed on the system The downloaded packages were saved in cache until the next successful transaction. You can remove cached packages by executing 'dnf clean packages'. Error: No available modular metadata for modular package Can you please suggest proper way to mirror CentOS8 repository in CentOS7 Server? Regards, Suresh PanneerSelvam

Not getting bootloader installed with CentOS 8 + mdraid
by Chris Adams 01 Jul '20

01 Jul '20

I am trying to use a kickstart to install CentOS 8.2 on a server with a pair of drives with Linux software RAID 1. The install completes, but the resulting system will not boot - I get "Booting from Hard drive C:" from the BIOS (Dell in legacy BIOS mode, not UEFI) and it stops. If I then start the installer in rescue mode and run grub2-install on the two drives, it boots okay. If I take out the RAID config and just install on the first drive, it boots fine - it appears to just be an issue with RAID. I tried my kickstart in a KVM VM with two disks, and it works there (I get RAID and a bootloader). Anybody else run into this? Any ideas? I've been installing from kickstarts for ages, including software RAID, but not CentOS 8 with software RAID until now. -- Chris Adams <linux(a)cmadams.net>

[OT] Bacula offsite replication
by Alessandro Baggi 01 Jul '20

01 Jul '20

Hi everyone, I have updated my backup server to CentOS 8.2. It runs bacula performing backup on disks. I would like to replicate backups on another offsite machine. I read about the ability to configure a new storage daemon in the offsite location and create a Migration/Copy Jobs. If I'm not wrong, it replicates only volumes but not replicate the catalog. I will try this. Another way to replicate the volumes on another server is using rsync. What is your suggestion about this topic? Thank you in advance. Alessandro.

virt-manager guest display resize not keep
by Jerry Geis 01 Jul '20

01 Jul '20

Hi All, I have CentOS 7 has host and CentOS 8 as guest. I ran the command: virsh edit CentOS8 and changed the vgamem to 65536. I Now get higher resolutions in the guest - I select the 4K resolution, all works. Then when I reboot I am back to 1024x768. Any thoughts on getting the C8 guest to keep its screen resolution ? Thanks, Jerry

Force package install using yum?

RPMFusion and NVIDIA driver problem
by Alessandro Baggi 01 Jul '20

01 Jul '20

Hi list, I'm on C8.1 and I'm trying to install NVIDIA driver from rpmfusion-nonfree repository but it returns: package kmod-nvidia-3:440.82-2.el8.x86_64 requires kmod-nvidia-4.18.0-147.el8.x86_64 >= 3:440.82-2.el8, but none of the providers can be installed - conflicting requests - nothing provides kernel < 4.18.0-148.el8 needed by kmod-nvidia-4.18.0-147.el8.x86_64-3:440.82-2.el8.x86_64 (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) and uname -r returns: 4.18.0-193.6.3.el8_2.x86_64 Seems that RPMFusion needs an update. Waiting for this there is a way to install this package without fall in problems? Thank you in advance.

fdisk boot partition
by Jerry Geis 01 Jul '20

01 Jul '20

I am trying to use CentOS 8 host to boot an image (OS X) that I created using dd. First I tried fdisk -l image_file.img - all looks good so I did fdisk image_file.img - this works - but seems in CentOS 8 fdisk there is no longer a toggle bootable flag option. How do I do that ? Thanks, Jerry
