You have been subscribed to a public bug:
On Ubuntu 12.04.1, ephemeral containers seem to conflict with NFS home
directories.
The user's home directory is on a remote NFS server.
The original container is created with
sudo lxc-create -t ubuntu -n foobar -- -r lucid --bindhome $LOGNAME
The ephemeral container is started with
lxc-start-ephemeral -o foobar
The user logs in to the ephemeral container. This hangs.
After that, any reference to the home directory -- inside or outside of
the container -- seems to hang.
mount in the container shows:
none on / type overlayfs
(rw,relatime,lowerdir=/var/lib/lxc/buildhost2-ubu10,upperdir=/tmp/lxc-lp-v92y7NU)
none on /mnt/home/builder type overlayfs
(rw,relatime,lowerdir=/mnt/home/builder,upperdir=/var/lib/lxc/buildhost2-ubu10-temp-loNNGB5/ephemeralbind/mnt/home/builder)
mount outside the container shows:
obnas1a:/vol/homes/builder 419430400 362328576 57101824 87% /mnt/home/builder
But sometimes, mount outside the container shows nothing for /mnt/home/builder
after the problem happens.
This seems 100% repeatable.
