Question
Is a fsck at boot with exit code 1 an issue?
Environment
The boot takes long time. When pressing the “Esc” key you will see messages similar to the following.
Answer
After an unclean shutdown or after a configured number of mounts a file system check is performed at boot. Due to the nature of filesystems there might be some issues when the check is performed.
Unless fsck can fix these errors automatically (as in the screen shot) there is no reason to worry.
