When you run 'lsof | grep /tmp/lol/disk2.img' does that say
'(deleted)' next to it? If so, it should also identify the process
id holding the file handle open, which is preventing the release of
the space.<br>
<br>
From the log output it looks like the failure to mount /proc inside
your container causes a failure, so I haven't understood how it is
that lxc-execute works. Therefore I'm wondering if the failure
handling is missing the logic to release the mounted image. I'm
curious to know if the space is released when /proc is properly
mounted and the container comes up cleanly.<br>

<div dir="ltr">Hello,
<div><br>
</div>
<div>I'm able to create containers
which use a single file for their
rootfs;</div>
<div><br>
</div>
<div>$ dd if=/dev/zero of=/rootfs.img
bs=1 count=1024</div>
<div>$ mkfs.ext4 /rootfs.img</div>
<div>-- other debootstrap commands
here --</div>
<div><br>
</div>
<div>The image runs successfully in
both lxc-start, lxc-start-ephemeral
and lxc-execute.</div>
<div><br>
</div>
<div>However if I then attempt to
delete the rootfs image after
running lxc-start or lxc-execute,
the disk space is not given back and
I have to reboot in order to reclaim
the disk space.</div>
<div><br>
</div>
<div>Does anyone know why this might
be happening? Perhaps LXC is keeping
a scale descriptor open somewhere?</div>
<div><br>
</div>
<div>Any help would be really
appreciated, can provide more
info/debugging if needed.</div>
