All the data files that are accessible in Linux based computers are placed in a big tree, called root directory and denoted as '/', in an organized form. These data files might be spread out over various devices. The mount command in Linux operating system allows you to attach a file system on a data storage media to the root directory. However, if the file system is faulty and you run fsck utility to fix the problem after mounting the disk using this command, severe file system corruption occurs. It causes critical data loss situations and calls for Linux data recovery.
The mount command tells the Linux kernel to attach the file system found on your hard drive volume in the /dir directory. The previous owner, mode, and contents of the directory become invisible after mounting, and as long as the file system stays mounted, the /dir pathname refers to the root of file system on Linux hard drive volume.
The following three types of invocations of mount command don't actually mount the volume:
· mount -h- It prints the help message on screen.
· mount -V- This invocation prints the version string.
· Mount [-l] [-t type]- The option lists all the mounted file systems that are of type “type” on your Linux hard drive. The -l option adds labels (like ext2, ext3) in the listing.
In current versions of Linux operating system, it is possible to mark the mount and submounts as private, shared, unbindable, or slave. The shared mount gives you an option to create mirrors of the mount.
Mount is an essential process for accessing data from any Linux hard drive volume. If the drive is not mountable, it cannot be accessed. Sometimes, when you try to mount a Linux volume, you come across the following error message that puts you in need of data recovery Linux:
“Wrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”
This problem is caused by dirty or corrupt file system. In such cases, you need to use Linux recovery software to get your mission-critical data back. The Linux data recovery applications enable you to thoroughly scan the affected Linux hard drive using advanced scanning algorithms.
Stellar Phoenix Linux Data Recovery is the best solution to ensure absolute recovery in all Linux data loss situations. The software recovers lost Linux data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system, including SUSE, Mandriva, Red Hat, Debian, and Ubuntu.
