I think this is the root of the problem:
Code:

Here is df -h (after a pct mount 106):
Code: 
udev                    16G       0   16G   0% /dev

And df -hi:

I can't figure out what needs to be done for it to start. Some help?
 
hi,

Code: 
/dev/loop3             512K   512K      0  100% /var/lib/lxc/106/rootfs

you ran out of inodes. if you have a bunch of empty or small sized files in the container somewhere (like /var/lib/php/sessions or something of similar nature), i suggest you delete as much of these as you can. you can also try to increase the inode size using tune2fs
