Background:
I am in the middle of researching a switch from VMware's free ESXi server to
Linux containers. I have found somewhat spotty documentation which in
general does not bother me, but I have come to a bit of a roadblock.
I use Gentoo as my distribution of choice (I have many machines running
Gentoo and I am not likely to switch anytime soon).
Gentoo has an unsupported script called lxc-gentoo that will go through the
motions of setting up a container. I have used this script to create a
container.
Problem:
While the container starts succesfully, it is not without a few messages
that concern me:
* Remounting root filesystem read-only ...
mount: / is busy [
!! ]
/lib64/rcscripts/sh/rc-services.sh: line 412: /etc/init.d/udev-postmount:
Permission denied
Everything proceeds as expected with me being able to ssh into the new IP
address, etc. The problem comes when I perform a
shutdown -h now
Once this command is run from within the container, I can no longer start
the container again with failure messages that look as such:
lxc-start: Permission denied - failed to create pty #0
lxc-start: failed to create the ttys
lxc-start: failed to initialize the container
These symptoms sound strikingly similar to the following email on this list:
http://www.mail-archive.com/lxc-users@lists.sourceforge.net/msg00867.html
I do see some speculation in the emails, but I am not finding a ready
solution that I see to implement.
Any help to resolve the above situations would be appreciated.
Cheers,
Buzz
