Recovering a Red Hat Linux System After a Power Outage

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

Today, the Linux operating system has carved a niche of its own. It has got a dedicated category of users who will happily pay for it if it ever comes with a price tag. The Linux system is secure, reliable, fast, and does not require hardware/software drivers to install them on the system. Having said that, even such a robust operating system can face corruption. Corruption can occur due to various reasons such as power outages, corrupt file system, human errors, damaged operating system, etc. In such cases, you should try performing appropriate corrective measures to sort out the issue. However, if you are unable to do so then you should use a third-party Linux data recovery software to perform Linux recovery.

Consider a scenario wherein you are working on a Red Hat Linux system. Suddenly, there is a power outage and the system shuts down unexpectedly. When you try to switch on the system, you fail to do so.

Cause:
The cause of this situation is that the Linux system has corrupted because of power outage.

Resolution:
If the problem is because of having a faulty hardware like bad hard drive or memory chip, the file system check may not be sufficient to resolve this problem. This happens particularly when the file system is corrupted. In such cases, the Red Hat boot process will produce an error message and guide you into a shell so that you can perform the file system repair yourself.

When the recovery shell dismounts all the file systems to mount the root file system in a read-only mode, you can perform full checks on it. To do this, you should run the e2fsck utility on the corrupted file system that will be able to resolve all the inconsistencies. Exit the shell and restart the system. The system will function normally now.

However, if you still are unable to recover the system then you should use a third-party Linux data recovery software to do the needful. Such read-only tools are able to recover the data safely without overwriting the existing data.

Stellar Phoenix Linux Data Recovery is a Linux recovery software that enables you to recover data from the corrupted Linux systems. It is supported by various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. This Linux data recovery software is able to perform ext2 recovery, ext3 recovery, and ext4 recovery. In addition, it can recover data from FAT12, FAT16, FAT32 file systems as well. This Linux recovery software is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

SCSI CRC Boot Errors May Cause Data Loss in Linux

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

Booting errors are very common in Linux operating system, which makes your system unbootable and unusable. The errors prevent your system from booting and render it totally inaccessible. They prove to be a big threat to your precious data. Such errors usually occur after unexpected system shutdown and hard drive data structure corruption.

Losing data from hard drive in such situations creates big problems for your business. So, you need to restore data from the latest backup to prevent data loss. However, in case backup is not updated or available, Linux Recovery solutions come to your help.

When you face boot errors, your Linux system refuses to boot properly. There are various types of boot errors, depending upon the type and cause of failure. One such error is SCSI CRC error. You may come across the below error message when your Linux operating system loads:

“Creating Root Device

mounting root filesystem

(scsi:0:0:0:0) CRC error during data-in phase

(scsi:0:0:0:0) CRC error in intermediate CRC packet

scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0 read (10) ……”

The above error halts Linux boot process, making your hard drive inaccessible. To retrieve lost data in such cases, identify the problem and perform Data Recovery Linux by resolving it.

Cause

On the first appearance, this issue seems to be associated with hardware problems, but this is not the case. You may face this behavior due to any of the below reasons:

• Damaged or missing /boot directory from Linux operating system installation.

• File system error or corruption.

• Missing or corrupted initrd.

/boot directory is a major component of Linux operating system, which contains critical information about booting parameters and process. While initrd is a temporary data structure, which makes preparations before mounting of root file system.

Resolution

Use Rescue CD of Linux operating system to overcome this problem by restoring damaged /boot directory and initrd. When it fails, go for Linux Data Recovery software to retrieve lost data.

The Linux Data Recovery applications are able to scan damaged Linux hard drive and extract all lost data from it. They have read-only conduct on the drive to ensure safe recovery, without modifying original data on the disk.

Stellar Phoenix Linux Data Recovery is the most comprehensive and advanced utility to ensures absolute recovery of lost data. The software works well with all major distributions of Linux operating systems, such as SUSE, Debian, Red Hat, Ubuntu, and Fedora. It recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

Are you unable to boot your computer from Linux operating system in a dual-boot configuration with Windows? Your system cannot recognize the Linux partition and you cannot access your data from the system? This behavior renders your Linux partition inaccessible and your valuable data irretrievable. Such problems may occur due to missing or corrupt hard drive data structures. It leads to significant data loss, if your backup is not updated. In order to recover lost data in these cases, linux data recovery comes for your rescue.

In a practical scenario, you may come across the below error message after you install Windows XP on a computer that has Linux Ubuntu already installed:

“root (hd1,1) Ubuntu/disks
Error 22: No such partition”

This problem occurs when you make your system dual-boot. After the above error message, boot process fails and you cannot gain access of your Linux partition. To get your valuable data back, you need to identify the root of this problem and perform data recovery linux by resolving it.

Grounds of the issue

You may encounter this problem due to corruption to the Linux partition or file system. Linux cannot read a damaged partition and access boot files from it.

A computer hard drive is divided into several partitions, which work as individual drives. You can use different file systems and can install different operating systems on these partitions as per your requirement. The hard drive partitioning is particularly useful for effective management of your precious data.

The hard drive partition and file system may get damaged due several reasons, such as virus infection, improper system shutdown, power outages, user mistakes, file system conflicts, and more.

Resolution

Try out the below methods to sort out this problem:

Boot your system from boot disk of Ubuntu operating system.

Run fsck tool to check integrity and consistency of your hard drive partition.
