As mentioned I already tested with a Kernel from 13.10 with the same result.
To be sure I installed a minimal Ubuntu 13.10 in a virtual machine and did the steps to reproduce the issue. -> The Problem existed in 13.10 as well. df@ubuntu-bug-check:~$ cat /etc/issue Ubuntu 13.10 \n \l sudo mount -t overlayfs -o lowerdir=/usr,upperdir=/mnt/delta overlayfs /mnt/test sudo lvcreate -s -n backup -L512M /dev/ubuntu-vg/root -> Hang I will attach the dmesg output to this post. A test using a mainline kernel does not work, because overlayfs is not (yet) in mainline: df@feretti-virt:~$ uname -r 3.15.0-031500-generic df@feretti-virt:~$ sudo mount -t overlayfs -o lowerdir=/usr,upperdir=/mnt/delta overlayfs /mnt/test mount: unknown filesystem type 'overlayfs' So I will set the tag to 'kernel-unable-to-test-upstream'. Please change that in case there is a tag better fitting the situation. Thanks for looking into it. ** Attachment added: "dmesg output on the 13.10 installation" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1328595/+attachment/4130901/+files/dmesg-1310.txt ** Tags added: kernel-unable-to-test-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1328595 Title: lvcreate -s hangs when overlayfs is in use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1328595/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
