Dell 5820 workstation failed to start crash recovery

[kadwm00]

I have 4 Dell 5820 workstation with 64Gb RAM, 512GbSSD, and 2Gb Radeon video card.

I now have 4 of these saying "[FAILED] Failed to start Crash recovery kernel arming."

What is going on here? A cursory search does not find anything specific. Have 4 more running Ubuntu 20 desktop with no problems.

Any ideas? At first I thought it might be hardware issue. I rebooted the workstation, and when I try to select my login ID, it presents the error message. I tried reinstalling one of them; same issue.

These 4 workstations were running CentOS 9 for at least a week or more before this problem.

You know CentOS Stream 9 is a beta product? If you want a rebuild of RHEL 9 then look at one of the other rebuilds listed in my sig below. Stream breaks too often for most of us to use and its target audience is really developers needing to build for something coming in the next point release of RHEL. Or possibly masochists.

The "Crash recovery kernel arming" service is really called kdump so systemctl status kdump might give you more info or you could just disable it as there are very few people that need the kdump service.

I suspect the error you get on login is not to do with the kdump service so you probably need to read logs/journalctl -xe output etc.

A wild guess at the problem that stops you logging in based on almost no evidence at all : If you have booted a different distro or in emergency mode, and edited /etc/passwd or group or shadow or used usermod/add from a boot like that then your files are probably labelled incorrectly for selinux to allow access. You would need to run restorecon -RFv against them to fix them. Possibly booting with 'enforcing=0' on the kernel command line would allow you to login.

Ah, ok. I must have missed the memo on CentOS 9. And CentOS 8 is ending this year as well.

There has been relatively lot of talk on topic since December 2020, when Red Hat announced "the shift in focus".
Alas, niches like this do not make mass media headlines, so what was a furious storm to some, was barely a breeze to others.

If you do think "CentOS" as "clone of RHEL", then CentOS 8 (CentOS Linux 8) died 2021-12-31, and there is no "CentOS 9" -- nor ever was.

CentOS Stream is not what the "CentOS of old" was -- it has a wery different purpose.
It is the CentOS Stream 8 that ends in May 2024 (while RHEL 8 lives on to 2029).

Thanks for the clarification. I'm a lab tech managing some Linux workstations and on a learning curve. We installed CentOS 7 to use some Cadence software packages for VLSI design. We also have a license for some software from Silvaco for simulating semiconductor stuff like diodes, transistors, and such. There is a Windows and Linux version with Silvaco. Trick question: which one runs faster on the same workstation?
