reiserfsprogs contains debugreiserfs, mkreiserfs, reiserfsck, resize_reiserfs and unpack. debugreiserfs can sometimes help to solve problems with reiserfs filesystems. If it is called without options it prints the super block of any reiserfs filesystem found on the device. mkreiserfs creates a reiserfs file system. reiserfsck checks a reiserfs file system. reiserfstune is used for tuning the ReiserFS journal. WARNING: Don't use this utility without first reading the man page thoroughly. resize_reiserfs is used to resize an unmounted reiserfs file system The unpack utility can be used to dump reiserfs filesystem information to files for debugging, much like debugreiserfs.
