System Problem Detected On Login [RAID]
Hi all,
Approx one week ago I built a new home file server, assembling 3x 10 TB disks into a single RAID5 mdadm volume (/mnt/md0). Array has been working great for the week and I transferred my ~15TB of data from the old server to this one. This morning I am getting an error on login 'System program problem detected'. Per the screenshot above, it seems the mdcheck_start.service is failing due to MD array scrubbing. What does this mean exactly? UPDATE It seems this mdcheck_start daemon is trying to launch a script in the path /usr/share/mdadm/mdcheck. Ubuntu 20.04 does not ship with this file and the mdadm packages do not install this file. Is this service even valid? Should I disable it? Code:
systemctl status mdcheck_start.service |
Looks like Ubuntu just copied this patch from OpenSUSE without much thought. The mdadm.spec from OpenSUSE contains this line:
Code:
install -m 755 misc/mdcheck %{buildroot}/usr/share/mdadm/mdcheck |

What should/can I do on my end to resolve this or is this something that I have to wait for Ubuntu to fix on their end? I'm guessing its kind of important for mdadm to be periodically scrubbing my array to keep it healthy, which is not currently happening... |
Well, nothing prevents you from downloading the OpenSUSE package, extracting the relevant files (those would be two shell scripts, /usr/lib/mdadm/mdadm_env.sh and /usr/share/mdadm/mdcheck as well as /etc/sysconfig/mdadm), adjusting them to your liking (e.g. changing /etc/sysconfig to /etc/default as is customary on Debian-based distros) and using them.

Thanks again for the responses! Update I found the script they forgot to include here. I made it executable, copied it to the appropriate directory, and started the service. The service now starts, though I am still getting this stupid error dialog on login, whatever it is isn't related to this broken service as the systemctl --failed command shows no failed services now. |
Open a bug against Ubuntu so others don't get bitten. As for the annoying pop-up, read this.
