Thank you for taking the time to file a bug report on this issue.
However, given the number of bugs that the Kernel Team receives during
any development cycle it is impossible for us to review them all.
Therefore, we occasionally resort to using automated bots to request
further testing. This is such a request.
With the recent release of this Ubuntu release, would like to confirm
if this bug is still present. Please test again with the newer kernel
and indicate in the bug if this issue still exists or not.
You can update to the latest development kernel by simply running the
following commands in a terminal window:
sudo apt-get update
sudo apt-get dist-upgrade
If the bug still exists, change the bug status from Incomplete to
Confirmed. If the bug no longer exists, change the bug status from
Incomplete to Fix Released.
If you want this bot to quit automatically requesting kernel tests, add
a tag named: bot-stop-nagging.
Thank you for your help, we really do appreciate it.
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Tags added: kernel-request-3.13.0-24.46

Title:
lvcreate -s hangs when overlayfs is in use
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I am using xbuntu 14.04 LTS in combination with KVM, lxc, logical volumes and
overlayfs.
After I started using overlayfs i realized that my backup based on LVM
snapshots made the system "go mad".
As described in the manual I tried the kernel from 13.10 (3.11.0-xx) with the
same result.
A test against main line does not help, since it does not include the
overlayfs support.
I tested the behaviour on a server as well as in a VirtualBox environment
with the same result:
lvcreate -s -n backup -L512M /dev/VG/NAME hangs and does not come back.
This issue is easy reproducable:
sudo mkdir /mnt/test /mnt/delta
sudo mount -t overlayfs -o lowerdir=/usr,upperdir=/mnt/delta overlayfs
/mnt/test
sudo lvcreate -s -n backup -L512M /dev/xubuntu-vg/root
-> Hang
