Damaged udev Device Manager Leads to Critical Data Loss in Linux

Tagged Under : , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Kernel is a core component of Linux operating system, which works as an interface between the application and actual data processing performed at hardware level. It is responsible for managing all of the system resources. Kernel uses a device manager to make its functions easier. For example, Linux 2.6 kernel series uses udev. Basically udev manages the device nodes in root directory. It also handles /dev directory and all of the user space actions while removing/adding devices. In case if you use new version of the udev with Linux kernel 2.6.13 or earlier, you may not boot your system and access data from your hard drive. Issues with the udev file causes critical situations of data loss and need Linux Data Recovery to be handled.

The udev device manager in Linux dynamically offers only nodes for devices that are actually present on your system. Though, the devfs used to offer same functionality, but udev has a number of reasons to prefer it over devfs:

It supports unrelenting device naming that doesn’t depend upon the order of plugging of devices into system. Default udev setup offers persistent name for storage devices. Hard drive is recognized by the unique file system id.

The execution of udev is completely in user space, in place of kernel space. It could execute arbitrary programs for composing name for devices from properties of device, before creating the node.

The simplest method to use the udev on your Linux system is to let the device manager send events via a socket to Hardware Abstraction Layer (HAL) that would carry out further device-specific operations. For instance, HAL would notify other applications running on your system that new hardware resource has arrived though a broadcast message on D-Bus IPC system to all of the interested processes.

For proper working of your Linux system, it is essential for udev file to be stable. In case if it gets damaged due to any reason, your system would become inaccessible and you come across data loss issues. At this point, Data Recovery Linux is required to get your valuable data back.

Linux Recovery is potential through efficient and effective third-party tools, known as Linux Data Recovery software. The applications are completely safe and easy to use and carry out absolute recovery in most of the data loss situations.

Stellar Phoenix Linux Data Recovery is the most comprehensive and efficient utility for successful recovery. It recovers lost data from Ext4, Ext3, Ext2, FAT32, FAT16 and FAT12 file system volumes. The software is compatible with most of the major distributions of Linux operating system including Red Hat, Ubuntu, Fedora, SUSE and Mandriva.

Linux Hard Drive Crash And Linux Data Recovery

Tagged Under : , , , , , , , , , , , , , , , , , , , , , , , , ,

Linux is a popular operating system, known as an actual techies’ operating system. The robust architecture and open source coding of the operating system insures that it can’t be affected by viruses and other malicious programs easily.

However, even the Linux is prone to situations where you may lose hard drive volumes and data. Hard drive crash is one such kind of situation that leads to significant data loss and needs Linux Hard Drive Recovery to be sorted out.

The hard drive crash is a situation where you cannot access your data from a properly configured system, however the data is still there. The hard drive may get crashed during normal computer operations, or because of external reasons, like power outages and heat. You must have an effective backup plan to save your data, but if it is not available; commercial recovery software and services are required to overcome the problem.

Linux hard drive may crash due to numerous reasons, which are broadly categorized into two major groups: Logical Failure and Physical Failure. Irrespective of the cause of hard drive crash, your data is still recoverable from Linux hard drive.

Symptoms of Linux hard drive crash

Computer is unresponsive or unbootable.

You encounter error messages, which indicates hard drive is unrecognized.

Black screen at start up.

Grinding or clicking sounds coming from hard drive.

System generally stops responding, restarts, or you cannot run any application.

Error messages related to missing or damaged data structures, like file system and Superblock.

When you encounter any of the above situations with your Linux computer, the very first thing that you need to do is determine the type of problem. Whether it is logical failure or it’s caused by breakdown of mechanical hard drive components.

In case of logical hard drive failure, you can recover lost data in a quick and easy way through Linux hard drive recovery software. The applications carry out extensive scan of whole hard drive using advanced scanning methods and extract all lost, missing, and inaccessible data from it.

Stellar Information Systems Limited is the foremost provider of both types of Linux Hard Drive Recovery solutions. The software is able to recover data from Ext4, Ext3, Ext2, FAT12, FAT16, and FAT32 file system volumes of all major Linux distributions.

Interrupted Logical Volume Extending Process Causes Data Loss in Linux

Tagged Under : , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

LVM (Logical Volume Manager) is a part of Linux operating system kernel, which manages hard drives and other mass storage devices. It is a way of allocating disk space into various volumes, which can easily be resized or extended instead of hard drive partitions. You can not place Linux /boot/ partition on logical volume group as it is not readable by the Linux boot loader.

You can easily extend a logical volume, using lvextend utility. It also supports extension of the snapshot logical volumes. Before you proceed for extending a Linux volume, you must first create an absolute backup of entire volume. In case the logical volume extending process gets interrupted or halted, you may lose access to logical volumes and encounter data loss. At this point, you have to opt for Linux data recovery software to get your valuable data back.

The lvextend command-line utility, offers you the following options to perform a series of operations on your logical volume-

-l, -extents [+]LogicalExtentsNumber[%{VG|LV|FREE}]: It sets or extends the size of volume in units of the logical extents. With + sign, value is contributed to actual size of volume and without this, value is accepted as absolute one.

-L, -size [+]LogicalVolumeSize[kKmMgGtTpPeE]: Sets or extends size of LV in the units of MB. The size postfix of M for MB (Megabytes), G for GB (Gigabytes), T for TB (Terabytes), P for PB (Petabytes), or E for EB (Exabytes) is elective.

-i, -stripes Stripes: Provides number of the stripes for extension. This option is not usable with the logical volumes, which use original metadata LVM format that must use single value throughout.

-I, -stripesize StripeSize: Provides number of the kilobytes for granularity of stripes. It does not work on volumes, which use original metadata LVM format that must use single value throughout.

All the above options are very useful in modifying a logical volume. However, serious problems occur if the process is interrupted due to any reasons, such as system crash, power outages, improper system shutdown, and user error. In such cases, the volume can not be accessed and you encounter severe data loss, which require Linux recovery to be fixed.

Data recovery Linux is best possible using advanced and efficient Linux data recovery software. They recover lost data safely and easily in all data loss scenarios.

Stellar Phoenix Linux Data Recovery is a read-only and easy-to-use utility that ensures absolute recovery of lost Linux data. The software works well with all major distributions of Linux operating system, including Red Hat, Mandriva, SUSE, and Fedora. It recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT 12 file system volumes.
