# Input/Output error and File Corruption on Linux Systems
---

This incident type relates to encountering input/output errors and file corruption on Linux systems. These errors can lead to boot issues for users and require troubleshooting to locate and unmount the affected device. The issue can be resolved using fsck, which automatically fixes errors.

### Parameters
```shell
export DEVICE="PLACEHOLDER"

export PATH_TO_LOG_FILE="PLACEHOLDER"
```

## Debug

### Check for file system errors
```shell
sudo fsck /dev/${DEVICE}
```

### Check disk usage and available space
```shell
df -h
```

### Check system logs for errors
```shell
dmesg | grep -i error
```

### Check file system mount points
```shell
mount | grep "${DEVICE}"
```

### Unmount a file system
```shell
sudo umount /dev/${DEVICE}
```

### Check file system type
```shell
sudo file -s /dev/${DEVICE}
```

### Check file system journal
```shell
sudo journalctl -k -b | grep -i "error"
```

### Check for bad blocks on a device
```shell
sudo badblocks -v /dev/${DEVICE}
```

### Check system logs and identify the root cause of the input/output error and file corruption.
```shell


#!/bin/bash



# Define log file path

LOG_FILE=${PATH_TO_LOG_FILE}



# Check log file for input/output errors and file corruption

grep -i "input/output error" $LOG_FILE

grep -i "file corruption" $LOG_FILE



# If issues are found, troubleshoot accordingly

if [ $? -eq 0 ]; then

    echo "Issues found in log file. Troubleshoot accordingly."

    # Add steps for troubleshooting here

else

    echo "No issues found in log file."

fi


```

### Repair file system errors automatically
```shell
sudo fsck -y /dev/${DEVICE}
