System Problem Detected On Login [RAID]
by thund3rstruck from LinuxQuestions.org on (#52ZS6)
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?
