Okay, I think it's all figured out. I made the change you suggested to
my test container and it mounted my LV to /mnt successfully in the
container. I then took another look at my other container and it looks
like I had a bad lxc.mount.entry entry (knew it had to be something
simple). I had:
root@reaver:~# cat /var/lib/lxc/ldap_baneling/config | grep lxc.mount.entry
lxc.mount.entry = proc
/var/lib/lxc/dns_defiler/rootfs/proc proc
nodev,noexec,nosuid 0 0
lxc.mount.entry = devpts
/var/lib/lxc/dns_defiler/rootfs/dev/pts devptsdefaults00
lxc.mount.entry = sysfs
/var/lib/lxc/dns_defiler/rootfs/syssysfsdefaults0 0
lxc.mount.entry = /mnt/lxc/ldap/tmp
/var/lib/lxc/ldap_baneling/rootfs/tmpnonedefaults 00
I'm not sure where I pulled "none" from for the fstype, but when you
mentioned that you didn't specify that in your config line either it
made me check mine (mine is xfs not ext4 but the point is the same). I
also changed thefile system line to "/dev/vg_lxc1/lv_ldap_tmp1" and
changed the mount point to just "tmp". Now I have:
lxc.mount.entry = proc
proc proc nodev,noexec,nosuid 0 0
lxc.mount.entry = devpts
dev/pts devpts defaults 0 0
lxc.mount.entry = sysfs
sys sysfs defaults 0 0
lxc.mount.entry = /dev/vg_lxc1/lv_ldap_var1
var xfs defaults 0 0
lxc.mount.entry = /dev/vg_lxc1/lv_ldap_tmp1
tmp xfs defaults 0 0
Everything seems to be working correctly now. Thanks for all your help,
Josh

Yes it failed to start:
1. lxc-create -n testme1 -t debian
2. root@reaver:~# cat /var/lib/lxc/testme1/config | grep lxc.mount.entry
lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0
lxc.mount.entry = sysfs sys sysfs defaults 0 0
lxc.mount.entry = /dev/vg_lxc1/lv_ldap_tmp1 lv_ldap
defaults,create=dir 0 0
Wait a sec. I mistyped. There's no fstype in there :)
That should be
lxc.mount.entry = /dev/vg_lxc1/lv_ldap_tmp1 lv_ldap ext4
defaults,create=dir 0 0
or whatever fstype it is in place of ext4. Sorry.
Actually I see that will fail too, because 'create=dir' has a
slight problem. We need to remove create=dir from the mount
options which we pass along to the mount syscall.
so for the sake of testing just do
lxc.mount.entry = /dev/vg_lxc1/lv_ldap_tmp1 mnt ext4 defaults 0 0
