Ubuntu releases after 10.04 LTS do no longer provide unfs3 to workaround OpenVZ and LXC containers limitations
You have to download, compile and install unfs3 from sources.
- Download unfs3
- decompress the archive : tar zxf unfs3-0.9.22.tar.gz
- apt-get install build-essential make flex bison
- cd unfs3-0.9.22
- ./configure
- make
- make install
- make install-init
- edit /etc/init.d/unfsd and replace the occurence of /usr/sbin/unfsd with /usr/local/sbin/unfsd
- /etc/init.d/unfsd start
- check unfsd is running : ps -ef | grep unfsd
- if it runs, then run update-rc.d unfsd defaults
Install and configure fog as usual.
If you want to setup a separate volume for your images :
- assuming you want to use a logical volume (LVM) /dev/vg0/lv with a ext3 filesystem :
- run your container and move all files located in /images into an other location (/root/images-bak), including the hidden file /images/.mntcheck
- from the lxc host, open /var/lib/your-container/fstab and add the following line : /dev/vg0/lv images ext3 defaults 0 0
- restart the container, and check the nex volume is available : run mount without any argument.
- If the LVM volume has been successfully mounted, move back the files backed up in /root/images-bak. Note there is no slash before images.
- chmod 777 /images
