Resolving Ext3 Error No journal on filesystem

December 10, 2015

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.

How to Fix Unable to resolve UUID Error in Linux

June 12, 2015

Modern distributions of Linux operating systems use UUID (Universally Unique Identifier) to uniquely identify hard drive or other data storage devices, in place of the conventional block names like /dev/sdb and /dev/hda1. It is due to the fact that UUID is never modified, even if the hard drive is switched. It is stable as compared to traditional methods, and prevents system failure and need of Linux Data Recovery solutions.

UUID is a 128-bit string that is used for making the Linux hard disk management simple. If you look at /etc/fstab file in your Linux computer, you find the entry in the following format, in place of the familiar hard drive designation:


In comparison to the traditional hard drive identification techniques, UUID is quite easy and reliable. For instance, in the traditional Linux systems, when you try to insert a new hard drive in a system that already has two hard drives, the drive is inserted between existing drives. At this point, ‘mount’ command attempts to mount the newly inserted drives as home.

In such situation, you need to log on as a single user for resolving the problem. However, when you log on, it gives you some error message and in the worst case scenario, you may encounter kernel panic. You can fix this issue using UUID.

UUID creates a unique entry for each hard disk volume in the Linux file system tree. Using UUID offers easy management of your Linux hard disks and creates less complication while adding or removing the disk.

Although, UUID is quite useful and it provides various advanced features, but it also has some faults. Sometimes, you may encounter the below error message when you attempt to access a UUID based Linux hard drive:

-Fsck 1.40.8 (13-Mar-200 fsck.ext3: Unable to resolve ‘UUID=d8533154-cef1-4cce-a823-9f3f74aab65b’-

After the above error message, you can not access the particular hard drive. All the data stored on your hard drive become inaccessible and you come across critical data loss. At this point, Linux Recovery Software come for your rescue.

The applications perform absolute Data recovery linux in most of the logical data loss situations, using advanced scanning algorithms. These tools enable you to perform Linux Recovery on your own as they have self-descriptive and simple graphical user interface. With read-only and non-destructive behavior, the applications are completely safe to use.

Stellar Phoenix Linux Data Recovery is the most comprehensive application for perfect recovery of all lost data. The software is compatible with all Linux distributions including SUSE, Debian, Red Hat, and Fedora. It recovers lost data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.
