Ext3 is a journaled file system and maintains a journal file to prevent instances of metadata corruption due to unexpected power outage. Due to its wide testing base and relative simplicity, the file system is considered to be safer than its counterparts. But it is not completely immune to crashes. At times, when using a Ext3 formatted drive, you might receive errors suggesting that system doesn't find any journal on the file system. As a solution, you might be compelled to reinstall the system. In such situations, you need to check the status of your backup that should be valid and completely updated to restore information from. But if you observe any backup related issues, Linux Recovery utilities should be used.

For an instance, while attempting to mount your Linux based hard drive, you might come across the similar error message:

"ext3: no journal on filesystem"

The system fails to boot and data remains inaccessible. If you make to boot the system somehow, you might observe some of the files and folders missing from the system.


Among various reasons possible for this behavior, some of them are as below:

  • You have recently updated the kernel but the process ended improperly

  • No or corrupted journal file

  • File system is severely corrupted


To try resolving the existing issue, follow these steps:

  • Boot the system using an installation disc and access the Rescue Mode. Mount the existing installation and reinstall the improperly installed kernel package

  • You can create the journal file by executing the below command:

  • tune2fs -j /dev/yourpartitionid

  • If above measures fail, try repairing the file using fsck. Boot the system using an installation disc and access the Rescue Mode. While making the system unmounted, run fsck for all the hard drive partitions except the swap partition.

If these measures don't help and your data still is not accessible, use Linux Data Recovery tools for successfully recovering your lost data. Linux Recovery applications incorporate high end scanning algorithms to scan the logically crashed media to recover data while maintaining their integrity.

Stellar Phoenix Linux Data Recovery is a world's known product to recover lost data from Ext2, Ext3 and ReiserFS based drives. The application employs powerful algorithms to result effective and safe data recovery. Embedded with advanced recovery features, this Linux Data Recovery tool supports most of the Linux distributions including Red Hat, SUSE, Ubuntu, SlackWare and others.
