I have been using systemd for about a month without any problems on my Debian Jessie. I installed it according to the Debian wiki. But all of a sudden today I got this error:

   ss of error

How can I fix this?

  • are you sure it's not your hard disk?

  • 4
    That looks a lot more like a physical disk problem (or your disk controller) than a software issue.

  • Agreed it looks like your HDD is dying/failing.

  • I would immediately run something like HDAT2 or Spinrite on the HDDs. See my prior A's: unix.stackexchange.com/search?q=user%3Ame+hdat2

The lack of systemd is the point where the system gave up because there was no more way to recover. When you see a series of errors, you need to go backward until you hit the root cause.

The lack of systemd was due to an inability to mount the root filesystem.

mount: mounting … on /root failed: invalid argument

This inability to mount was due to the block device containing the root filesystem (which here is identified by a UUID) not being available.

It is highly likely that the block device in question is a partition on the disk concerned by the error messages immediately above. A series of messages like

end_request: I/O error, dev sdc, …

is a bad sign about the disk that is identified as /dev/sdc. The CPU detects that a disk drive is present isn't able to read data from the drive. The cable or the drive is failing (or, a lot less likely because you'd have noticed before, the driver is buggy).
