it is possible to get such a corruption that fsck will need to insert some extra metadata to successfully repair the fs. this process may run out of disk space. I have an improved version of reiserfsck, which detects these corruptions and avoid these metadata insertion. however your fs already has these metadata inserted and there is probably no space to proceed. I will send you that improved reiserfsck, if it runs out of disk space too, you need to enlarge you partition, enlarge fs, and run reiserfsck again. If you will need to enlarge the partition, before doing it, please zero the space that will be added into the partition to avoid mixing your reiserfs metadata with another reiserfs metadata. > Now it is flagged as unmountable "to prevent further corruption".
