Linux Recovery Through reiserfsck Options

ReiserFS supports journaling and is used in many Linux distributions. When it suffers inconsistencies, reiserfsck can correct it. Reiserfsck is more like a Linux Recovery tool that can help replaying the transactions, detecting and repairing damaged file system for the specified device. The basic syntax is as follows

Reiserfsck

There can be different check and repair options used in the command that are used according to issue:

• --check: This is the file system check option and can be used on file system that has been mounted as read-only.

• --rebuild-tree: This option helps rebuilding the file system with the leaf nodes found on the device. But this repair can introduce more corruption issues if is interrupted or used on device with extremely damaged tree structure. Thus it is recommended to backup all the data first to avoid Data Recovery Linux.

• --rebuild-sb: It is used when superblock is corrupt. It generally replaces the damaged superblock with the backup copy.

• --clean-attributes: It cleans out reserved fields of Stat data items.

• --fix-fixable: If –check option reports suggest using –fix-fixable command, it helps removing corruption when it doesn´t require entire tree building.

• --journal device , -j device: This is the option used to give the name of current file system journal that lies on device other than main.

• --logfile file, -l file: It helps reporting corruption to the log specified.

• --badblocks file, -B file: It clears badblock list and sets it as the list of blocks specified in the file.

• --nolog, -n: Using this option prevents reiserfsck to report corruption

• --quiet, -q: It prevents reporting rate of progress.

• --yes, -y: It inhibits asking for confirmation.

• -a, -p: It prints information about specified file system and performs few checks.

• -V: It prints reiserfsprogs version.

• --no-journal-available: It is used when no journal is available.

• --scan-whole-partition, -S: Used with --rebuild-tree to scan whole partition.

• --adjust-size, -z: It corrects file sizes that are found to be larger than the last discovered byte offset.


But if corruption can be removed using these options, we need to recover lost data after recreating the file system. Linux Recovery applications can do it. These are the graphically rich applications that safely offer Data Recovery Linux.

Stellar Phoenix Linux Data Recovery is the safe application to recover lost data from ext2, ext3 and reiserFS file systems. The software has interactive interface. This Linux Recovery software can recover data from most of the Linux distributions like RedHat, Caldera, Suse, TurboLinux etc.
