Hello all,
OS: Ubuntu 14.04.1 LTS
LXC Version: 1.0.6-0ubuntu0.1
Experienced a weird issue when I tried to launch a container which mounts
an additional logical volume (ext4 formatted) through the container's fstab
file:
# cat /var/lib/lxc/mycontainer/fstab
/dev/vglxc/apps mnt/apps ext4 ro 0 0

I've read that mailing list post yesterday, too and was actually hoping
this could solve the mount issue. When I looked at it, it seems that this
patch hasnt been merged into the github repo yet, correct?
Will try it and let you know.

I applied the patch but it does not work for the read only mount.
lxc-start 1416993491.172 INFO lxc_conf -
conf.c:check_autodev:3821 - Autodev not required.
lxc-start 1416993491.172 ERRORlxc_conf - conf.c:mount_entry:1916
- Device or resource busy - failed to mount '/dev/vglxc/
I made a couple of mistakes in my modified patch - so please ignore
that.But the basic idea of it was to handle special mount flags (in this
case RDONLY) before it hits
if (mount(fsname, target, fstype, mountflags & ~MS_REMOUNT, data))
Will be glad to test additional patches for you.

I'm pretty sure it's NOT lxc's fault.
For starters, have you tried testing the same (i.e. mount rw, and then
mount again ro) in normal, non-lxc setup? That does not work, and does
indeed fail with a message like this
mount: /dev/zd208 already mounted or /mnt/tmp2 busy
mount: according to mtab, /d
Fajar, thanks for your response and you're right.
I did some testing on the physical host before I wrote to the mailing list
but mounted twice the same LV as rw.
Now I just did as you said and tried to do a rw mount followed by a ro
mount. Indeed the same behavior:
# mount /dev/mapper/vglxc-apps
