anyone know of a list or wiki for GWC?
by Fred Smith 26 Feb '20

26 Feb '20

Hi! totally OT... Hoping there is a mailing list or wiki (or other help forum) for GWC, but haven't found one yet. I'm working on converting a bunch of my LPs to CDs, and am using GWC (Gnome Wave Cleaner, or GTK Wave Cleaner) to clean up the noise. It works great, but I can't figure out how to deal with certain types of pressing flaws that create a thump every time around. Anyone know of such a resource? Thanks in advance!

Downgrade Mariadb 10.3 on centos 8 ?
by Ian B 25 Feb '20

25 Feb '20

We've just got a new server running centos 8 and mariadb 10.3.17, so there's no real data loss issues currently on that server. We've also got some older servers running mysql 5.1.7 which can't be upgraded currently. We can't connect to the old mysql servers using libmysqlclient (to be more precise Perl using DBD::mysql which uses that to my understanding). We get a 'handshake error', and digging about it suggests that it's mysql version incompatibilities. Really we need the new servers connecting to the old and vice versa. So I'm wondering how I get around this. Is downgrading Mariadb on Centos 8 the only (or possible) route here ? If so, any idea how we can go about this (I can't seem to find any information on what version would work either)? Happy to explore any other routes, other than changing the old servers currently. Thanks, Ian

dbus/systemd failure on startup (CentOS 7.7)
by James Pearson 25 Feb '20

25 Feb '20

We are seeing a problem that occurs ~5% of the time when rebooting CentOS 7.7 where systemd gets a 'Connection timed out' to D-Bus just after the D-Bus service starts - from 'journalctl -x' : ... Jan 21 16:09:59 linux7-7.mpc.local systemd[1]: Started D-Bus System Message Bus. -- Subject: Unit dbus.service has finished start-up -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit dbus.service has finished starting up. -- -- The start-up result is done. Jan 21 16:10:24 linux7-7.mpc.local systemd[1]: Failed to register match for Disconnected message: Connection timed out Jan 21 16:10:24 linux7-7.mpc.local systemd[1]: Failed to initialize D-Bus connection: Connection timed out ... This then has a knock-on effect that causes other services to fail - e.g. -- Unit gdm.service has begun starting up. Jan 21 16:10:39 linux7-7.mpc.local dbus[817]: [system] Activating systemd to hand-off: service name='org.freedesktop.login1' unit='dbus-org.freedesktop.login1.service' Jan 21 16:10:50 linux7-7.mpc.local dbus[817]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out Jan 21 16:10:50 linux7-7.mpc.local systemd-logind[1221]: Failed to enable subscription: Failed to activate service 'org.freedesktop.systemd1': timed out Jan 21 16:10:50 linux7-7.mpc.local systemd-logind[1221]: Failed to fully start up daemon: Connection timed out Jan 21 16:10:50 linux7-7.mpc.local systemd[1]: systemd-logind.service: main process exited, code=exited, status=1/FAILURE Jan 21 16:10:50 linux7-7.mpc.local systemd[1]: Failed to start Login Service. -- Subject: Unit systemd-logind.service has failed -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit systemd-logind.service has failed. -- -- The result is failed. Whatever the issue is, it appears that polkit might be involved - if we restart the polkit service, things appear to return to normal (e.g. gdm starts up etc) We can't find any similar reports of this happening elsewhere with CentOS 7.7 - but we were wondering if anyone else had come across a problem like this? Thanks James Pearson

Nested Virtualization with CentOS 7 host and CentOS 8 guest
by Chris Card 25 Feb '20

25 Feb '20

I'm not sure whether this is a specific CentOS question, but I'm hoping someone here can give me some pointers. I have an OpenStack compute node running CentOS 7.4.1708 and kernel 3.10.0-693.17.1.el7.x86_64 which is configured for nested virtualization; this has been set up for a few years and works fine when running CentOS 7 guests which themselves are using virt-create / virt-customize etc. Nova is set up on the compute node so that guests have cpu mode host-passthrough. I have been trying to run a CentOS 8 guest on the compute node so that I can build CentOS 8 images for OpenStack (there is an issue using a CentOS 7 server to build a CentOS 8 image related to xfs options which are only supported read-only by CentOS 7). However, every time I try to build a CentOS 8 image using a CentOS 8 guest, the CentOS 8 guest crashes with a kernel panic, not immediately but usually near the end of the image build process. (I have also seen similar behaviour using a Fedora 31 guest to build a CentOS 8 image, but the crashes are less frequent, and some image builds have succeeded). The CentOS 8 guest is running CentOS 8.1.1911 (Core) and kernel 4.18.0-147.3.1.el8_1.x86_64. Any ideas?

Problems with reposync and createrepo on CentOS 7 for RHEL8/CentOS8 repo?

OwnCloud vs NextCloud
by H 25 Feb '20

25 Feb '20

I am planning to install either ownCloud or NextCloud on a CentOS 7 VPS server I control. I have previously used ownCloud on another server but have not updated the host application for quite some time. On this new server, I am not sure which one is the "best" and since I am doing a new install I need to decide which one to use. Looking at the Android apps for these cloud solutions, they both seem to have a fair number of critical reviews... Does anyone have a preference and, if so, why?

tftp server different from dhcp one
by Mauricio Tavares 24 Feb '20

24 Feb '20

In https://docs.centos.org/en-US/centos/install-guide/pxe-server/#chap-install… they show the following example for setting dhcpd.conf to point to the tftp server for pxe booting: option space pxelinux; option pxelinux.magic code 208 = string; option pxelinux.configfile code 209 = text; option pxelinux.pathprefix code 210 = text; option pxelinux.reboottime code 211 = unsigned integer 32; option architecture-type code 93 = unsigned integer 16; subnet 10.0.0.0 netmask 255.255.255.0 { option routers 10.0.0.254; range 10.0.0.2 10.0.0.253; class "pxeclients" { match if substring (option vendor-class-identifier, 0, 9) = "PXEClient"; next-server 10.0.0.1; if option architecture-type = 00:07 { filename "shim.efi"; } else { filename "pxelinux/pxelinux.0"; } } } If the server is a different one, how would the option architecture-type{} change to reflect the file location?

C8 network install
by Robert G (Doc) Savage 23 Feb '20

23 Feb '20

I'm building a new storage server. I was unable to use the CentOS-8- x86_64-1905-dvd1.iso image written to a 256GB thumb drive. It kept failing the integrity check. I had to use the much smaller CentOS-8- x86_64-1905-boot.iso image and do a network install from a mirror site. That's a first for me. Even though I selected "Server with GUI", the resulting installation boots to a text prompt. I've installed the GNOME and GNOME Applications groups, and I can get to them by typing 'startx'. How do I change this behavior and make it boot directly to a graphical desktop? --Doc Savage Fairview Heights, IL
