The troubleshooting information about the following system statuses are covered in this topic:

  • fsck_err_corrected

  • fsck_reboot

  • fsck_err_uncorrected

  • fsck

Upon each reboot, a filesystem check (fsck) is performed automatically by the system. Results of this check are stored in /var/log/fsck.log, which is parsed to generate the warnings described in this section.

fsck errors are common, usually not critical, and are usually fixed automatically by a reboot. If problem indications persist, it may be an early indicator of disk quality degradation. Check other indicators for filesystem or disk issues.

If serious problems are confirmed by other indicators, consider backing up important data stored in the filesystem. If the issues are critical, a full reinstall of the system through USB with the “format partitions” option will rebuild the filesystems (and wipe all existing data). If the problem is in the hardware or the disk’s firmware, a disk replacement may be necessary.

Command Executed

fsck.ext4 -f -y -v [dev] , where [dev] is the partition to be checked.

Example

fsck.ext4 -f -y -v /dev/sda8

Note that the partition needs to be unmounted for this command to work. For more information on how to run this command manually, see https://support.zpesystems.com/portal/en/kb/articles/how-to-fix-file-system-errors

Issue Identification

  1. Summary Message: File system errors corrected
    On the last reboot, some file system issues were successfully corrected. This message should be cleared the next time the system check runs. If desired, the full output of the system check correction can be checked at /var/log/fsck.log

  2. Summary Message: File system errors corrected, reboot needed
    On the last reboot, some file system issues were successfully corrected, but a new reboot is recommended for fixes to fully take effect.

  3. Summary Message: File system errors uncorrected
    The automatic procedure was unable to fix some filesystem errors. Check the full log in /var/log/fsck.log for more details. If this message is accompanied by other indicators of filesystem or disk issues, corrective action may be necessary.

  4. Summary Message: fsck errors

    Unknown errors were found during last fsck run. Check the full log in /var/log/fsck.log for more details.
