Hi guys.

After few days, some of my containers are not able to write in some directories anymore.

Example:

root@controller002:/# touch /toto
root@controller002:/# touch /tmp/toto
touch: cannot touch '/tmp/toto': No such file or directory
root@controller002:/# touch /usr/toto
root@controller002:/# touch /usr/local/share/toto
touch: cannot touch '/usr/local/share/toto': No such file or directory
root@controller002:/# apt install strace
E: Could not open lock file /var/lib/dpkg/lock - open (2: No such file or directory)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
root@controller002:/# touch /var/lib/dpkg/lock
touch: cannot touch '/var/lib/dpkg/lock': No such file or directory

The application needs to create sockets but it can't and it fails with a trace like that:

  File "/var/lib/kolla/venv/local/lib/python2.7/site-packages/eventlet/wsgi.py", line 514, in handle_one_response
    write(b'')
  File "/var/lib/kolla/venv/local/lib/python2.7/site-packages/eventlet/wsgi.py", line 453, in write
    wfile.flush()
  File "/usr/lib/python2.7/socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
  File "/var/lib/kolla/venv/local/lib/python2.7/site-packages/eventlet/greenio/base.py", line 385, in sendall
    tail = self.send(data, flags)
  File "/var/lib/kolla/venv/local/lib/python2.7/site-packages/eventlet/greenio/base.py", line 379, in send
    return self._send_loop(self.fd.send, data, flags)
  File "/var/lib/kolla/venv/local/lib/python2.7/site-packages/eventlet/greenio/base.py", line 366, in _send_loop
    return send_method(data, *args)
error: [Errno 32] Broken pipe

If I restart the container, it's works. Make me think something related to overlayfs and some layers issue.

Do you need more information ? I'll have to restart the container :/
I would like to provide you the most as I can !

EDIT: I've added some information.

Maybe it's something fixed in kernel 4.8 or 4.10 ?

I don't know of any issues which would cause this. After you restart are you able to reproduce getting the container into this state? Also can you list the directory contents for each of the files which complained about the directory not existing? Is there any process in the container that could be responsible for deleting files? Also look at the mount and check whether all the lower directories still exist on the host.

@dmcgowan yes, I'm able to reproduce the state (sometimes it's few days, sometime it's a week).

The directories are not empty (except for /tmp), there is nothing deleting files (this issues appends in different containers on different hosts).

All directories still exist on the host.

I do see Live Restore Enabled: true, wonder if there's anything related to that that may cause the issue (filesystem being re-mounted after daemon is restarted e.g.?) - sorry just thinking out loud.

@goldyfruit Do you know if this occurs after the daemon was restarted?

@thaJeztah I don't remember but I just tested to restart the docker deamon on an another host and I don't have any issue.

You suggestion is not a bad one, how can I confirm that the filesystem are not remounted ?
The live-restore option is not recommended ?

Thanks for your time guys !

@thaJeztah I'll turned off the live-restore until we have a clear view the impact.
I'm not 100% sure that it's not the issue.

Any other thoughts guys ?

No other thoughts at this point, but keep us posted if disabling live-restore makes a difference
