Description of problem:

I put a disk in my system and turned it on and then mounted it's single partition and then decided to force e2fsck on it. I unmounted it first but e2fsck reports that it's busy. lsof shows jbd2 (kernel process?) doing something with the disk.

e2fsprogs-1.41.14-2.fc15.x86_64

e2fsck to force fsck for this filesystem

See bug 808795.  It appears related.

Comment 2 Milan Broz 2012-04-12 06:47:59 EDT

And bug 809188 as well.

We found some very strange unmout path called in VFS, seems like it keep internally some reference.

I have system where it is easily reproduced, so I will try to work with Lukas to move it somewhere, it hits too many people already.
