Had the same problem as imperia777 : data intact, error message and
unable to fix it, (though no actual power failure).

Here's fsck output:

e2fsck 1.42.9 (4-Feb-2014)
myfsname: recovering journal
Superblock needs_recovery flag is clear, but journal has data.
Run journal anyway? yes

fsck.ext4: unable to set superblock flags on myfsname

Final verdict was: defective storage.
Data was transferred to a new storage medium with a new filesystem.
Problem solved.

As additional check, we made a copy from the defective medium to another
and observed that fsck could run flawlessly on the sane medium.

Looks like fsck is extra cautious and checks if every operations indeed
happened, which allowed it to spot the trouble.

Anyway, to say it again: "fsck.ext4: unable to set superblock flags on 
myfsname" meant (at least in my case): change your storage medium.
Thank you for your attention.
