[gentoo-catalyst] Catalyst 2.0.6_pre9 mksquashfs hangs building squashfs + solution

[Pongracz Istvan]

Hi,

This evening I run into a problem, when I built my custom livecd.
It contains an installed and configured postgresql and one of its file
had something, which caused to mksquashfs hanged up.

So, after I append the -info (mksquashfs argument), I caught a file,
which caused the problem several times.

After asking my old spanish friend (Manual) and google, I used the
-no-sparse argument to avoid hanging mksquashfs.

After it I succeed to create the image.

I am not sure, but it seems, it is safe to use the -no-sparse argument
to avoid some problems. 
Just my experience.

Bye,
István

Are you sure it was hung? Was it just trying to squash a very "large" sparse 
file? Can you give us the URL that gave you the idea to use -no-sparse?

I'm pretty sure: the file is around 237kbyte large and first time about
40 minutes "hanging" I pushed Ctrl-C (I'm usually patient :) - in fact,
I was with my children, I left the machine to do the job...)
It was 97% of the total, I was a little bit upset :)

or

Probably the situation is not the same, I did not compared it to my
version (3.3).

I gave it a try and it solved this issue for me.

This also happens if you're using mksquashfs 3.3 and trying to make a
3.1 squashfs, like would be done if your kernel is 2.6.23 and you're
using ~arch on your build machine.  We *want* the sparse option, so the
"fix" is to use the right version of mksquashfs for the kernel you're
building/deploying.

Eh, he was talking about mksquashfs hanging while creating the squashfs image, 
not about the kernel freaking out while trying to mount it.

[gentoo-catalyst] producing a DVD

[Lanza Fabrizio]

 Hi,
I need to produce a DVD instead of a CD .iso. How do I tell catalyst to
produce a DVD? Should I change fstype?
 Thank you.

I do not know, is there any difference between DVD or CD.
My iso image sometimes 800-900 MBytes and booting from the iso image is
working well with virtualbox/qemu.

Try to write out your image to a dvd and boot from it with real
hardware. I did not try this.

Correct me, if I was wrong.

[Lanza Fabrizio]

 Yes, it's different. My CD .iso does not work in qemu, because it's 900M. It gives an error that it is out of space. Also, I cannot burn it on a DVD. I used Nero, which complained that it was a CD and not a DVD.

 So, I need to produce a real DVD filesystem.

 Best,
 Fabrizio

Ugh, please don't reply to another thread to start a new one. It screws up the 
threading in Thunderbird (and probably other mail clients).

Unless catalyst has some "magic" to figure out to build an image with a UDF 
filesystem instead of ISO9660 (and I'm pretty sure it doesn't), you can burn a 
 >700MB ISO to a DVD and it will work just fine. For the past few releases, 
we've released >1GB standard ISO images for use on a DVD, and nobody has 
reported a problem booting them.

That is exactly what I cannot do. I insert a DVD in the CD/DVD drive. I
start Nero, choose "burn image", I select my .iso, and it ejects the DVD
saying that I have the wrong medium, and that it is supposed to be a CD.
Every CD/DVD mastering software will check what you are going to burn.
If it has a CD project/filesystem, it won't burn it on a DVD.
Also, since qemu does not load CDs larger than 700M... there is a
problem.

I also noticed a curious thing. When I mount the .iso (larger than 700M)
with a program such as Daemon Tools, it won't show the filesystem. It
shows as it is completely empty.

I managed to convert the big .iso to a DVD .nrg with Nero, and I could
burn it indeed. It boots fine, but it has the same problem that the
filesystem is not visible.

I would rather find out the way I can get a DVD iso with Catalyst.

Best,
Fabrizio

Just one thought.
One of my friend also had problems with Nero. My opinion, forget it.

I already told you. Catalyst doesn't do anything special for DVDs, and the 
larger ISO images it generates work just fine. There is zero support for 
creating UDF images in catalyst. Use another program to burn the image. Nero 
obviously has an issue. Burning a larger ISO with cdrecord works without a problem.

I use: cdrecord -v -sao dev=/dev/sr0 driveropts=burnfree /path/to/iso

I've been able to successfully burn the 4GB LiveDVD for both AMD64/x86
and had exactly 0 issues in about 40 burns.  Again, your tools are being
stupid.  They are thinking that the image *must* be UDF when they are
not required to be, at all.

Remember that we're burning using Linux-based tools, not Windows-based
ones.  I have no clue how to provide you support for Windows, nor will I
even try.  Sorry.  Try burning it under an OS that doesn't suck and if
you're still having problems, let us know.

> Every CD/DVD mastering software will check what you are going to burn.

Umm... no.  A DVD can be *either* UDF or iso9660.  If your software is
refusing to work with >700MB ISO9660 images, it is broken.

Broken.  File a bug.

Windows.  Try the same under Linux and it'll work.

Well, catalyst produces images which are within the ISO spec.  If your
tools do not work with them, submit patches.  Otherwise, we're not going
to change anything, as we're within the defined specification which
other tools are supposed to follow.

Hi,

Correct, I have ths problem with creating, not mounting.

Anyway, I use gentoo-sources-2.6.23-r6 and ~x86.
I made some livecds before and this was the first time, when I run into
this kind of problem.

Check this out:

Sorry, nabble is down for maintenance now, I found this in the google
cache.

István
