Reiserfs Partition Corruption And Linux Recovery

ReiserFS is an advanced and journaled file system used in Linux. When ReiserFS was first introduced, it offered major capabilities that were not available in existing Linux file system and its later developments enhanced its popularity. Where features like Tail packing and journaling somehow contributes to avoid Linux Data Recovery issues, they also make it a good performance file system. So, ReiserFS partitions offer maximum performance in data retrieval by offering for fast and safe data access. 

When on one side ReiserFS partitions are chosen for secure data storage, they can also become corrupt mostly due to logical reasons. Users report that these partitions can become corrupt in cases like Superblock corruption, fstab file errors, partition table issues, partition resizing errors, incompatible software and virus infection. Unsupported hardware can also cause partition corruption. 


As a result, the partition may fail to boot or mount. ReiserFS follows B+ tree structure with leaf nodes as the building components. So, general rule to solve partition corruption issues is to use –rebuild-tree with reiserfsck command.

Note: Reiserfsck –rebuild-tree is not safe. It can cause further damage to ReiserFS structure if finds internal tree unusable, so it is recommended to backup all information before using the command. The backup must be checked. Incomplete or damaged backup will lead to Linux Recovery need. 

When the computer is booting, fsck starts automatically if operating system finds errors related to partition health. However we need to run fsck –rebuild-tree command, if initial repair is unsuccessful. The command rebuilds whole tree from scratch. Though it may damage the file system, if it finds leafs unreadable. In such cases we can just format the partition and restore the data from an updated backup. 

Linux Data Recovery

Linux Recovery is required if user has lost data with no recent backup. Data recovery industry offers a powerful solution to solve such issues. Linux Recovery software can scan and recover lost information in any logical data loss issue. These applications use powerful scanning algorithms which enable them to safely recover all lost data.

Stellar Phoenix Linux Data Recovery is the robust application to recover data from ext2, ext3 and ReiserFS based disks. The application offers Data Recovery Linux using most powerful scanning algorithms. It is interactive in nature with advanced recovery and restoration options. This Linux Data Recovery software supports all major Linux distributions.
