BTW, since you asked earlier about the order of make-rslave etc, check out the table at bottom of http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-oneiric.git;a=blob;f=Documentation/filesystems/sharedsubtree.txt;h=4ede421c9687a71d33027b95118c90dc743da0fe;hb=HEAD which shows you what each action actually does based on current state. So for instance if you do make-rslave on an unbindable node, you're not really turning it into a slave (bc there is nothing for it to be a slave of). > cat >> /var/lib/lxc/containerX/fstab << EOF > /share/containerX /var/lib/lxc/containerX/rootfs/share none bind 0 0 > EOF > > 2.

I tried for about a minute to get this done with /var/lib/lxc/containerX/fstab, i.e. cat >> /var/lib/lxc/containerX/fstab << EOF /share/containerX /var/lib/lxc/containerX/rootfs/share none bind 0 0 none /var/lib/lxc/containerX/rootfs/share none make-rslave 0 0 EOF but make-rslave doesn't seem to be valid for fstab. I can dig around the source later, but does anyone know offhand of a way to do make-rslave through fstab? > The only problem remains is that the partitions mounted under /share are > unmounted the moment the container is shut down.

Hm, turning it into a slave should prevent that. -serge ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
