Scenario: Mail/web server with file corruption. I have I/O errors on a few blocks which results in regular (daily) server crashes (including kernel panic) at random times during the day, usually afternoon CET. I need to run fsck on the disks. I have grub2 installed on the server.
If you have "I/O errors on a few blocks", it seems to me that the hardware your virtual hosting provider uses to host your server is either defective, dying, or misconfigured, and you should address *that* as a matter of urgency.
The systemd-fsck service *should* run automatically, as far as I can tell from casual inspection of the relevant systemd unit files, but if you are actually getting *I/O errors*, fsck is not going to save you.
