Linux Filesystem Read-Only and Aborted Journal

Linux primarily supports Ext2, Ext3, and ReiserFS file systems. All the files are organized in directories, which are further arranged in a tree-structure format. The root directory (which is represented by ´/´) serve as the trunk of this tree, from where all the directories originate. If due to any reason this structure suffers inconsistencies, the file system may fail to mount.

In such situations, you can´t access your data and hence, to restore the information, you need to use your recent data backup. But if backup gives errors or is not updated, you require using Linux Data Recovery applications.

Consider a practical instance, you try to mount Linux file system and receive the following error message:

"Remounting filesystem read-only"

This error message is further followed by another error:

"Detected aborted journal"

The journal file replays if it finds inconsistencies with the system. In this case, this file has been aborted.

Cause

You encounter the above error messages, if one of the following conditions is true:

• Hard disk or hardware issues

• The Linux file system is forced to go into read-only mode if busy I/O retry error marks any low-level disk call as failed

• Hard disk file system corruption issues

Solution

To remedy the above problem, you can use these methods:

• Check the system for possible hardware issues and replace the faulty ones, if any.

• Try restarting the system, if there has been an I/O error

• Check if your /etc/fstab has the following entry:

device] [mountpoint] ext3 errors=remount-ro 0 0

In case of I/O errors, this entry tells the file system to remount as read-only.

• To correct file system corruption, try running fsck. This is a command-line tool that allows repairing most of the file system corruption problems. If problem persists, you need to reformat your hard drive and restore lost data from backup. However, in case of backup issues, scan your hard drive with Linux Recovery applications. Such software make use of high-end scanning algorithms and prove effective and safe tools for Linux Data Recovery.
