`/bin/bash -c pwd` does not work in extracted directory with Btrfs

[paulepanter]

Using a Btrfs partition for storing the containers, extracting an archive and running ./configure.

    # ./configure 
    pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
    configure: error: working directory cannot be determined
    root@file:/tmp/file-5.08# pwd
    /tmp/file-5.08
    root@file:/tmp/file-5.08# /bin/bash -c pwd
    shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
    pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or director
    root@file:/tmp/file-5.08# ls
    ls: cannot open directory .: Stale NFS file handle

Using Ext4 works as expected.

This isn't going to be an issue in 0.7. AUFS is being dropped (temporarily) in favor of device mapper.

[crosbymichael]

@paulepanter Can you try this again with docker 0.7?

[paulepanter]

Sorry, we do use Ext4 instead of Btrfs now. So I cannot test. Unclejack was able to reproduce this though I think.

[unclejack]

@paulepanter is right, I can reproduce this issue using the steps he's provided.

[unclejack]

There's a native btrfs driver now. That one should be used instead of attempting to use AUFS on top of btrfs.

I'll close this issue now since we're not going to support AUFS on top of btrfs for now. Please feel free to comment.
