Hi again,<br>
<br>
I'm having another problem with overlayfs and unprivileged lxc
containers. When cloning with overlayfs, I get <br>
"overlayfs: missing upperdir or lowerdir or workdir"<br>
but cloning appears to succeed.<br>
<br>
I was using ubuntu 14.04 as host OS. Since overlayfs got kernel
support in 3.19 kernels, I updated the kernel to 3.19 using the
packages linux-headers-generic-lts-vivid &
linux-image-generic-lts-vivid. I then recreated a new mother
container, without adding a user to it. I cloned it again using
lxc-clone -o mother2 -n overlay2 -B overlayfs -s and got again the
error:<br>
<br>
[130.841743] overlayfs: missing upperdir or lowerdir or workdir<br>
Created container XY as snapshot of X<br>
<br>
Although it starts the clone despite that error, I still keep
getting "failed to whiteout" and "Operation not permitted" when
doing lengthy installations, see previous thread.<br>
<br>
Here:<br>
<a class="moz-txt-link-freetext" href="https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1409425">https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1409425</a><br>
they report the same problem with
<meta http-equiv="content-type" content="text/html; charset=utf-8">
lxc-start-ephemeral, and claim it to be fixed with current version.
After upgrading to lxc version to 1.1 using the
ppa:ubuntu-lxc/daily, I still get <br>
"overlayfs: missing upperdir or lowerdir or workdir"<br>
<br>
However, fortunately after the update to lxc 1.1, non-trivial
installations succeed !! I tried by installing wordpress and >
150MB of dependencies, which repeatedly failed before.<br>
<br>
So, my remaining question is: can the error message be simply
ignored?<br>
"overlayfs: missing upperdir or lowerdir or workdir."<br>
<br>
<br>
Thanks for clarification,<br>
<br>
