subject: Resolving mounting Unchecked File System Error In Linux [print this page] Dirty system shutdown or improper system shutdown is a common problem with computer system. It affects every computer operating system including Linux. The improper system shutdown generally occurs due to system crash or power outages. This behavior generally affects the computer file system and results into serious data loss situations. File system corruption renders all of your valuable data inaccessible and require Linux Data Recovery to retrieve lost, missing and inaccessible data from affected Linux hard drive.
In such critical situations, you are required to run the e2fsck (if you are using the fsck front end tool then run the fsck -t ext2) with -a option for clearing the dirty flag of your file system. After that, you can proceed to cleanly unmount the hard drive partitions during every proper shutdown.
The simplest method to do it is to install the latest version of fsck, shutdown and mount commands. When you install it, you need to make sure that all of your /etc/rc* scripts properly work with them.
You should never try to check a Linux file system, which is mounted in read/write mode. It includes the root partition of hard drive, if you do not see the following:
VFS: mounted root ... read-only
During the boot process, you are required to arrange to mount root file system as read-only to start with. Verify whether it is required and then you can remount the file system in read/write mode. In order to get the procedure of doing so, you can refer the documentation, which comes with operating system.
You should always specify the -n options for mounting the file system so that it does not update /etc/mtab file of your Linux file system. The root file system is mounted in read/only mode, update in /etc/mtab file may cause file system failure and need Data Recovery Linux. In such situations, you can encounter below error message:
EXT2-fs: warning: mounting unchecked file system.
In these critical situations, Linux Recovery software come for your rescue. They are advanced and effective third party applications, which methodically scan the entire damaged hard drive and retrieve all of the data from it. With simple, interactive and rich graphical user interface, the Linux Data Recovery tools are pretty easy to use. The software do not ever alter original data as they have read only conduct.
Stellar Phoenix Linux Data Recovery is the most advanced and efficient application for assured recovery of lost data. It recovery data from all hard drive volumes that have Ext4, Ext3, Ext2 or ReiserFS file system. The softwre is usable with all major Linux distributions.
