So, as we can see, fsck doesn't fix the corruption.
Kernel reports read-only mount, while mounting it rw.
In the result we have an impression that fsck makes things worse.

Every time I check one same partition it warns me that same files are corrupted.
After fsck.reiser4 --build-fs those errors aren't fixed. Strangely, if
I read it correctly, one same cluster containing 3 files is corrupted.
In logs on mount:
