Re: [linux-lvm] Unmounting file system hangs up...

[Thinking Outside the Well <rod rook gmail com>]

Thank you for your quick response, Andre. 
I agree you are right on your suggestion that Fedora is trying to umount a network file system. I think it actually is trying to umount a CentOS file system installed in another hard drive. The reason why I think that way is that whenever I log on to CentOS, it complains that something is wrong with the file system and checks it 

Do you know how to tell Fedora not to umount CentOS file system?

You should find exactly which command hangs.
It might be as simple as a fs that it cannot umount because it's busy.
Or maybe something like Fedora trying to umount a network file system after the network has been shut down.

In doubt, check the health of your disk with fsck, badblocks and smartmontools.
