why does the kernel report it is in use?
if that would be true it could not be unmounted

I just saw a similar report on #ext4; do you still have a jbd
thread running for this filesystem?
this is a ext2 filesystem

Also, in the spirit of useful bug reporting, what kernel
are you running?
always the lastest fedora kernel
3.18.7-100.fc20.x86_64
Can you run strace of e2fsck, and see if an open(O_EXCL) fails,
or find some other hint about how e2fsck decided it was in
use? Possibly paste the last couple hundred lines of strace
somewhere.
i will try that on a non-production machine
This may be better suited for a bug report, or a thread on
linux-ext4, than the fedora-kernel list.
yes, my intention was to first ask if the problem is known and maybe
even a solution inthe pipeline and if not finally catch the needed infos
like the strace in the initial bugreport
after it's created i will respond to this post with the link
FWIW, the errors below do look indicative of a filesystem
that has never had the superblock written out during an
actual unmount...
likely because the -n param
the corruption itself may come from
https://bugzilla.redhat.com/show_bug.cgi?id=1192834 which is also really
strange
