Red Hat Bugzilla – Bug 810393
e2fsck reports device busy but that device was unmounted successfully
Last modified: 2012-04-12 16:00:40 EDT
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.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
e2fsck -f /dev/sde1 complains that the device is busy
e2fsck to force fsck for this filesystem
See bug 808795. It appears related.
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.
