"Root inode is not a directory" Error in Linux

By: jonny defh

The disk check command in Linux, fsck, runs in five phases. The first phase is to check the data blocks and its size while in second one, this check for the pathnames. Then in the subsequent phases, connectivity, reference counts and cylinder groups are checked respectively. If at the second phase, in which the pathnames are checked, the fsck fails, the situation could be drastic.

This can happen due to inode issues. You may get error messages like:

"Root inode is not a directory. Clear?"

This is the clear indication that the root inode has got corrupted somehow. Now what are inodes? The inode in Linux file systems are the data structures which hold all the information of the files stored except its name and data. This can be referred as the unique number given to each file and for each file there in an individual inode. The file is accessed by this inode only.

Now in this particular case, the root inode which is usually the inode number 2 has got damaged. This is the first inode of the file system and represents the root or starting point of the filesystem.

If you agree to 'Yes' in this error message, then this will delete the parent entry of each inode from the root directory. Then in the third phase of fsck, the root inode is attempted to recover, but if this fails, another error message displays:

"Cannot Allocate Root Inode"

The situation to be weird to those who possess lots of critical and important data on their Linux systems as this is the stage where they can lose their data. The only option to recover the data is to have the Linux recovery tools which gain the capability to retrieve the data even in the filesystem issues.

These tools are called Linux recovery software which makes use of the influential algorithms to drag out the data. Once written data does not move from the hard drive, until you overwrite it, so Linux data recovery software go along this fact and put maximum efforts to recover the data.

Data recovery Linux is not so easy job to be done through any of the software but instead demands high technology from the software. These Linux recovery utilities provide an abstract view to the users.

Stellar Phoenix Linux Data Recovery software works as the ultimate solution for data recovery Linux. Valuable for Ext2, Ext3 and Reiser FS file systems, this software uses the most powerful scanning algorithms to recover the data. Giving the interactive user interface to the users, it does the complete job for Linux data recovery.

  • Some Preventive Measures to Avoid Server Crash By: Andrew Watson - Server is the most important component of a network environment and it is operated on 24x7 bases. Thus as compared to general hard drive, the server hard drives are more susceptible to crash or failure. Businesses generally use RAID (Redundant Array or Inexpensive Disks) configuration because of extent of the data redundancy and extent of failure resistance if provides through several levels. Nevertheless of the storage system, the data loss still happens and cause critical situations for the organizations.
  • RAID 3 Failures and Recovery By: Fun Anku - RAID 3 supports byte-level data striping across multiple disks. It implements fault tolerance by sending parity information to a disk dedicated to store parity information. As compared to file system block, the strip across the disk is quite smaller. So, all the read/write operations are performed at high performance rate. RAID 3 can tolerate failure of one hard disk. It simply implies that when a single point failure occurs, the dedicated parity disk does not show it.
  • Partition Loss in Windows Due To Corrupted Boot Record Signature By: mnkstllr - The BIOS (Basic Input/Output System) in a Microsoft Windows computer is a boot firmware, which provides all of the boot information to computer processor for proper booting of your system. In the first physical sector of BIOS, MBR (Master Boot Record) is stored. MBR loads the first sector of your boot media, either hard drive or floppy. After successfully loading first sector, BIOS examines last two bytes of the boot sector (that is 55AA).
  • Get dedicated servers for effective net flow By: JessicaThomson - Basically, as per the recent trend net is used in executing task in almost every field. So, the usage and need of net has certainly hyped up to a great level. Net is effective in almost every task we do ranging from daily routine work to the hard core official work as such.
  • Data Entry is Most popular Services in BPO Industry By: Offshore Data Entry - BPO industry is the fast, dynamic and boosting industry of businesses world. Data entry outsourcing is such a fast growing services in BPO industry. In this environment easiness use, accurate and high quality data information is necessary. Data entry services cover most business and professional activities, including data conversion, document processing and photo manipulation. Data entry service is one aspect of a business which is undertaken on a huge scale by several companies.
  • Missing or Corrupt Vgaoem.fon File May Cause Partition Loss By: mnkstllr - A number of Microsoft Windows users upgrade their operating systems to Windows XP from earlier version to take benefit advanced and dynamic features of Windows XP. But in some situations, after upgrading to Windows XP, you might encounter a number of error messages and can not boot your system. In such situations, all of your hard drive partitions and stored data become inaccessible and critical partition loss situations occur.
  • Partition Recovery In case of False System Partition By: mnkstllr - The Windows hard drives, which contain dynamic hard drive partitions, are known as dynamic disks. Dynamic disks support multi-partition volumes and store the partition information on the hard drive itself. LDM (Logical Disk Manager) is a Windows subsystem, which is purposed for managing disk partitions. LDB uses the information of LDM database, which hold partitioning information. In general, the dynamic disk is comprised of MBR (Master Boot Record), followed bye LDM database and LDM partition.

  • Choosing MS Outlook over Lotus Notes By: tech nova - For successful business operation, both time and communication go hand in hand. For completing a given task within time, it’s necessary to have proper communication between the personnel, who are striving to complete it or professionals involved into the project. Emails works as the best way of communication within or outside the business entity. One may say emails are the most preferred messaging system.
  • What to do while Hard Disk Failure? By: Fun Anku - Basic Consideration while Physical Hard Disk Failure: • You should never open a failed hard drive to attempt repairing damaged internals or recovering lost data • A hard disk with failing or failed read/write heads or actuator produces unusual sounds like clicking, scratching and grinding sounds. It usually indicates that head is trying to make contact with disk platters. Thus, you should immediately turn off the system.
