[Bug 1629509] Re: Cannot mount overlay with upperdir on overlay

 

Would it be possible for you to test the latest upstream stable kernel?
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the
latest v4.4 stable kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Title:
  Cannot mount overlay with upperdir on overlay

Status in linux package in Ubuntu:
  Incomplete
Status in linux source package in Xenial:
  Incomplete

Bug description:
  I have a docker setup using overlay as its storage driver. I mount an
  overlay in the container. Both the lower, upper and work directories
  are themselves on an overlay filesystem. This mount started to fail
  after upgrading to kernel 4.4.0-38 from 4.4.0-34 with the error
  message "overlayfs: filesystem on '/mnt/overlay/upper' not supported
  as upperdir".
