I had to recreate the volume, so I lost the old filesystem. It was backups, so not a big loss. Generally, running the file system check and repair tool can be expected to automatically repair at least some of the inconsistencies it finds. In some cases, the following issues can arise:.

To ensure that unexpected or undesirable changes are not permanently made, ensure you follow any precautionary steps outlined in the procedure. Journalling maintains a transactional record of metadata changes that happen on the file system.

In the event of a system crash, power failure, or other unclean unmount, XFS uses the journal also called log to recover the file system. The kernel performs journal recovery when mounting the XFS file system. In this context, corruption means errors on the file system caused by, for example:.

When XFS detects corruption in the file system or the file-system metadata, it may shut down the file system and report the incident in the system log. Mounting an XFS file system with a corrupted log results in a failed mount and the following error message:. Although an fsck. If the mount fails with a structure needs cleaning error, the log is corrupted and cannot be replayed. The dry run should discover and report more on-disk corruption as a result. Any errors are printed and an indication of the actions that would be taken, without modifying the file system.

A pre-repair file system metadata image can be useful for support investigations if the corruption is due to a software bug. Patterns of corruption present in the pre-repair image can aid in root-cause analysis. The resulting metadump file can be compressed using standard compression utilities to reduce the file size if large metadump files need to be sent to support.

If the mount failed with the Structure needs cleaning error, the log is corrupted and cannot be replayed. Use the -L option force log zeroing to clear the log:. This command causes all metadata updates in progress at the time of the crash to be lost, which might cause significant file system damage and data loss.

This should be used only as a last resort if the log cannot be replayed. The ext2, ext3, and ext4 file systems use the e2fsck utility to perform file system checks and repairs. The file names fsck. These binaries are run automatically at boot time and their behavior differs based on the file system being checked and the state of the file system.

A full file system check and repair is invoked for ext2, which is not a metadata journaling file system, and for ext4 file systems without a journal. Active Oldest Votes. Improve this answer. David Foerster David Foerster 34k 54 54 gold badges 85 85 silver badges bronze badges.
