Severe Data Loss in Linux Upon Running fsck on Mounted File System

By blogger on

Are you unable to mount your Linux hard drive volume? The problem could be due to corruption the Linux hard drive data structures. To sort out such problems, Linux provides fsck utility. It is a command-line utility, which checks integrity and consistency of Linux file system, finds errors, and tries to fix them. However, in case if you run this utility on a mounted or online file system, you may come across catastrophic data loss situations. At this point, you need to carry out Linux Data Recovery to get your valuable data back.

If you mistakenly run fsck on a mounted Linux file system, the root iNode may got damaged and all iNodes start calling similar blocks. When you try to mount the volume after fsck, you may encounter the below error message:

-Mount: wrong fs type, bad option, bad superblock on /dev/hda1, missing codepage or helper program, or other error. In some cases useful info is found in syslog — try dmesg

tail or so-

After this behavior of Linux operating system, when you run ‘dmesg’, as stated in the above error message, you encounter further error message:

-EXT3-fs: corrupt root inode, run e2fsck-

When you run e2fsck, as suggested in above error, it gives you further error message stating:

-Root inode is not a directory. Clear?-

If you say ‘yes’ to above error, then it goes to fix the problem and then remove parent entry for each iNode in root directory. When you unallocate root iNode and blocks manually, and then try to rebuilt root iNode, it says that it can not allocate any block in file system.

Cause

This behavior is caused due to corruption to the file system, superblock, root iNode, or any other Linux data structure. Operating system can not locate the hard drive volumes and stored files, after corruption to the data structure.

Resolution

To sort out this problem and perform Ext3 Recovery, you need to format the hard drive and reinstall operating system. Although, this method is able to fix most of the hard drive related problems, however also deleted all hard drive volumes and files.

This entire behavior cause serious data loss situations and need Ext3 Recovery software to extract lost data. The applications perform Data Recovery Linux in a quick, safe, and easy way.

Linux Website Hosting Pros And Cons

By blogger on

As many of you may be aware, Microsoft Windows is the most popular operating system (OS); and therefore most web hosting companies cater to sites running on Windows. However, there is an increasing demand for hosts that can support websites running on other platforms such as Mac OS and Linux etc. Linux website hosting is not a new concept and is, on the contrary, rather popular.

Linux is an open source operating system, designed after Unix. This entails that Linux is free and this plays a major role in its increasing popularity and demand. Aside from being free, Linux is also known to be very stable even in when it comes to heavy-duty multitasking. Linux is also flexible, powerful, portable and has a great graphical user interface (GUI). Regardless of this though, there are many people who severely dislike Linux website hosting.

Linux, like all operating systems and all hosting systems has its positives and its negatives which need to be considered carefully before you decide whether this kind of hosting is for you and caters to your specific needs or not. One of the greatest advantages of Linux is that it is highly reliable and well known for not crashing or causing any such related problems.

Linux’s open source nature enables it in fact, to more presence on the internet than Windows web hosting. Linux web hosting provides users with a lot of flexibility at almost no cost which in turn enables developers and programmers to experiment with different innovations. There are no license costs etc involved and this makes it more comfortable for people to experiment and one can update their technology rather frequently without having to worry about additional costs.

However, it is undeniable that certain problems do arise despite the fact that it is an open source software and problems can be remedied easily. Linux’s open source is also very flexible for various distributions in the sense that when web publishers and hosting services need to add things to the system, the system is continently already programmed to integrate such items.

More and more people are turning to Linux web hosting and there are a lot of affordable packages being marketed by web hosting companies for the Linux user. Linux is a perfectly reliable eCommerce platform which is why it is fast becoming the first choice for those who publish content on the internet for commercial reasons.

One of the key things that set Linux apart are the costs involved- an obvious reason for its gaining popularity. Small business owners that may be on a budget will assuredly be attracted to the cost-effectiveness of Linux. However, many small businesses are new to the world of hosting and are used to using Microsoft software. Unfortunately for them, Linux is not compatible with Microsoft software.

This is a massive disadvantage and steers many people away from resorting to Linux. You should note that there is some visualization software that can help you use some Microsoft compatible system but might require an experienced set of skills that not everyone possesses.

Linux web hosting is also highly standardized and one does not have to worry about adding content to their website that may be streamlined. You’ll begin to notice the importance of this as your website expands and your business grows. Linux web hosting also enables you to be a better webmaster by assisting you with long-term management and diligent maintenance. Before choosing Linux web hosting over Windows web hosting you should heavily weigh your pros and cons and most importantly pick the one that suits your needs the best despite which system gets better reviews or is more popular.
