[livecd-creator] ioctl: LOOP_CLR_FD: Device or resource busy

[Davidson Paulo]

Hi,

I'm trying to build a Fedora 8 Live CD using livecd-creator with a
hand-made kickstart, but I experiencing the following problem that
occurs after all the packages are installed:

#  livecd-creator -c ~dpaulo/fedora-full.ks
--cache=/srv/revisor/livecd-cache/ --fslabel=F-8-Live-1
(...)
  Installing: system-config-keyboard       ##################### [533/533]

Software versions:

 * kernel-2.6.24.4-64.fc8
 * livecd-tools-013-1.fc8
 * yum-3.2.8-2.fc8

I'm attaching fedora-full.ks kickstart file.

Thanks a lot,

Is there space enough in your /var/tmp?
You can set "-t /home/user/tmp", for example, to point it to use another
directory with more space.

Hi Diego, first I tried another partition, /srv/revisor, which has
4GB+ of free space, more than enough to a Live CD installation. Once
the installation failed, I was unable to umount /srv/revisor partition
too, even rebooting the system. I'm wondering if this is not a kernel
issue...

Thanks,

Hi,

this sounds similar to the issue I mentioned earlier in this
list ("ext3 issues")

After the live cd creation run 

lsof | grep install_root

On my system the file
/var/tmp/imgcreate-O5Rka3/install_root/lib/libnss_files-2.7.so
was still open so the unmount has to fail.

This is not happening here. It's interesting the fact I can't umount
install_root/ directory, but I can umount /dev/loopX after what I can
delete install_root/.

Another issue: I used /srv/revisor as the temp directory. /srv/revisor
is a separated partition. After livecd-creator execution I can't
umount /srv/revisor (device or resource busy) even if there is no
active mount points under it, and the disk space previously used
during the livecd creation process are not freed in any form,
requiring a system reboot.

I ran "lsof | grep revisor " but nothing was shown. Strange...

Right now, I'm installing Fedora 8 on a virtual machine to use
livecd-creator within. Want want to know if these problems are related
with hardware incompatibilities of kernel. What do you think?
