Subject: fsck.ext4 taking a very long time because of "should not have
 EOFBLOCKS_FL set"

Hello,

yesterday i was forced to start a fsck of an ext4 filesystem (4 TB on
a encrypted raid5 array). After a while a got a lot
of those messages:
Inode 23565579 should not have EOFBLOCKS_FL set (size 0, lblk -1)

After some googling i found this thread
http://kerneltrap.org/mailarchive/linux-ext4/2010/8/19/6885408/thread#mid-6885408

Since it's something that can be taken care of by using "-p" i started
it yesterday and was kind of surprised
to discover it running happily today with no sign of stopping. I piped
the output to /dev/null since the printing
of the messages alone caused quite a bit of load so i don't know at
which inode fsck currently is.

Is there a way to speed things up? If i understand the thread
correctly those errors should self correct over time
and i don't want to wait anymore. Can i do any harm by killing fsck
and start it again without the pipe to see
at which inode it currently is?

Bye,
Johannes
