Impossible to umount a volume when commited

[tehmoon]

Hello,

I've attached a volumes to a containers using --volumes to /altroot, copied my files i needed, shutdown the process and commited the container.
When I started a new containers from the new image it seems that my volume /altroot was still mounted on the container:

root@f1e370dea651:/# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda9        17G  3.7G   13G  23% /
tmpfs           500M     0  500M   0% /dev
shm              64M     0   64M   0% /dev/shm
/dev/sda9        17G  3.7G   13G  23% /.dockerinit
/dev/sda9        17G  3.7G   13G  23% /altroot
tmpfs           500M     0  500M   0% /proc/kcore

I tried to run my containers in privileged mode to umount and then commit, but I've not succeeded to remove properly the mounted point.

 $ docker version
Client version: 0.11.1
Client API version: 1.11
Go version (client): go1.2
Git commit (client): fb99f99
Server version: 0.11.1
Server API version: 1.11
Git commit (server): fb99f99
Go version (server): go1.2

Keep up the good job guys :-)

I wonder if this would be fixed by #4885.

Look like this is fixed in 1.2 Issue should be closed.

Mounted volume that the image is committed with is missing now.
