[gentoo-user] DVD and large files

[gentoo-user] DVD and large files

[Dale]

Hi folks,

After getting the mailing list working I did some techy shopping.  I got 
me a new DVD burner and k3b does not like large files.  I used Kbackup 
to create a tarball of my data.  K3b gives me a error saying the file is 
to large.  I did some googling and searched around on the forums, even 
posted on one thread, but I can not figure out how to get this thing to 
burn.  Will it just not burn large files or what?

I also tried switching to cdrtools with no change.  Oh, also recompiled 
k3b after changing that, just to make sure.

Thanks

How big is the tarball?
# ls -lh <tarball>

Check if you have set the Medium size correctly in K3b. Maybe you try to 
burn it on a CD...

He will advise you to unmerge cdrkit and merge cdrtools, but first 
please look for the size of the tarball and the options set in K3b

Hey, Dale!
Nice to see you back!


I believe it means your archive is too big for the media disk you.

Are you trying to write 4.7[GiB] on a 4.7[GB] DVD disc?

4.7 GB  (giga) = 4.7 x 10^9 = 4700000000   (DVD media disc capacity)
4.7 GiB (gibi) = 4.7 x 2^30 = 5046586572.8 (the "too large" file)

"Gibi" is often incorrectly called "giga" which leads to confusions.

Should be: "I believe it means your archive is too big for the media
disk you are trying to use."

My apologies.

I did set it to write to the DVD.  The tarball is about 4Gbs or so.  It 
should fit on the DVD with no problems.  I tried a lot of different 
settings tho.  Still no joy.

I don't think that file will fit on a CD.  LOL 

Maybe this will help:

Hi again,

I decided to try the fixed setting instead of my custom one.  I usually 
set them to be a little less than full but I just told Kbackup to do it 
for a 4.7Gb DVD.  Will post back what blows up when it gets done chewing.

Is that the exact error message?

Hi,

I put the debug "stuff" in the reply to Sebastian's email.  From the way 
I understood the error, it could not handle a file larger than 2Gbs.  
May be reading it wrong tho.

Got another test in the works at the moment.  Hope it will work.

If you want to be really pedantic, it should be "media disc" :)

When CDs were introduced, Philips reverted to the correct spelling of
disc.

That's right, why do you think the files on video DVDs come in 1GB
chunks. You need to split the tarball to put it on a DVD. I use dar for
backing up to DVDs, it handles these details for you.

LOL  Never looked in a DVD before.  Sort of my first one here.  o_O  
That sort of sucks.  I was hoping for one whopper file instead of a few 
little ones.

Oh well.

You are correct, the genisoimage program is a fork from a very old
version of mkisofs. Enhancements and bugfixes done during the past 3 years are
not available in the clone. Instead, new bugs have been added by the 
maintainers.

Be careful: genisoimage claims to support larger files but the created 
filesystem images are broken. Mkisofs did add support for files > 4 GB 
aprox. 2 years ago. Mkisofs added support for importing multi-session
files > 4 GB from old sessions in May 2008.

As this is an extension to what the basic compatibility mode allows, you of 
course need to _allow_ mkisofs to write files larger than 4 GB.

See the mkisofs man page ------> you need iso-level 3 or 4.

4GB is about the limit. Please give the exact size.

The maximum size of a single file on a video DVD is "1 GB - one sector".
This is to allow historical (e.g. Mac OS 9) OS that is not large file aware.

The "largefile awareness" starts with the ability to correctly handle files 
that are > "2 GB - 2 bytes". Mkisofs is "largefile hot" since 10 years 
(Solaris) and supports large files on Linux since Linux started to introduce 
this feature.

As ISO-9660 level 1..2 limits files to 4 GB - 2 kB, we are not talking about
"large file" support but about something different.

If you are using "cdrkit", you use a "fork" that has been created in September 
2006, but that is based on code published in September 2004. As the cdrkit 
project does not do own development, all new features and bug fixes done in the 
official software are missing in the fork.

If you need features implemented during the past 3 years, you cannot use the 
fork, _need_ to use the official software.

I needed to write 4GB files to DVDs up until three years ago. I no longer
need to do this, hence I was unaware that mkisofs now has this
capability.

I did try level 3 and still no joy.  Also tried UDF or something and no joy.

I got Kbackup to make 1Gb tarballs and it still does not burn.  I got 
something like this:

umount: /media/hdd is not in the fstab

So, I added it to fstab and it is burning away.  I will try large files 
next and see just how big I can get.  Plan to try the 4Gb sucker just 
out of curiosity if nothing else. 

I thought you didn't need fstab entries for CD/DVD stuff?  O_O

Thanks for the help tho.  Learned something new.

You may either have an old k3b binary or the k3b sor some reason still uses the 
fork.

I guess it is possible.  This is what I did try tho.

1215138661: === Unmerging... (app-cdr/cdrtools-2.01.01_alpha34)

1215139599:  ::: completed emerge (1 of 1) app-cdr/cdrkit-1.1.6 to /

I did try both versions just to see and still gave me a error.  NOT to 
start a flame war here but which one is the most 'up to date' package?  
Or should I say gets maintained the best?

May I also say this thing burns pretty swift.  It's faster than a 
CD-RW.  Just wish the buffers would stay "fuller". 

Thanks

Now some other thoughts.  I got it burned and k3b even played the 
successfully burned tune for me.  When I insert the DVD, it opens in a 
new window but shows no files on the DVD.  Now what?  The files are just 
under 1Gb in size.

My fstab line:

root@smoker / # cat /etc/fstab | grep hdd
/dev/hdd                        /media/hdd              
auto                    noauto,users    0 0
root@smoker / #

Ideas?

This is a strong hint that you still used "genisoimage" instead of the real 
software.

"genisoimage" creates broken filesystem images that use the remainder to 4 GB as
"filesize". There is no support for file content bejond 4 GB - 2kB in 
genisoimage.

How do I get rid of genisoimage?  Can I unmerge it or something?  Can 
k3b live without it?

Hi again,

After getting a LOT of help on this, I got it sorted out.  This is what 
is installed:

[ebuild     U ] app-cdr/cdrkit-1.1.8 [1.1.6] USE="unicode -hfs" 0 kB

I also noticed something else that was "funny".  I added the line to 
fstab but sort of forgot something else.  This is one of my blonde 
moments here, not blonde but anyway.  I forgot to make the mount point, 
you know, the hdd directory in /media.  < Dale slaps forehead >

The proof is in the puddin tho:

That's a BIG file.  Now I want a blue ray thingy.  o_O  Then I can make 
HUGE files.  lol

Thanks for all the help.  Sorry for making such a silly mistake tho.  :/

Actually if you don't care about the GUI and compatibility with other
systems, you can do DVD burning with growisofs only (without
mkisofs/genisoimage respectively from cdrtools or cdrkit).

AFAIK this might cause problems if you use auto-mounting software and
forget to disable it before writing.

The good part is that you don't need isofs for DVDs. Actually
you don't need any fs at all. You could write files like this:

growisofs -Z /dev/dvd=Test-_2008.07.04-10.06.53_1.tar

Unfortunately I have I/O errors (ruined media) often with this method,
so I use:

tar cp path/to/files | \
pipebench -q -b 50000000 | \
growisofs -Z /dev/sr0=/dev/fd/0

"pipebench" is in portage and provides two important advantages:
- you can check the speed and make adjustments it if necessary
- you can adjust the buffer (-b)


To restore the files from the above backup:

tar xpf /dev/dvd

It works perfectly for me.

You can burn this way images with your preferred FS.

Well, it seems tar can not handle 4.7Gb files any way.  I'm not sure why 
but it seems happy with 2.2Gb files.  Anybody know about the upper 
limits on tar?

Also, is there a incremental GUI back-ip tool?  I found reoback but 
haven't tried it yet.  I like Kbackup but it is all or nothing.

Well, Kdar does the making part.  I'm not doing anything fancy when 
unpacking it but when I do it with it set to 4.7Gb, I get a error about 
half way though unpacking.  I can't recall the error at the moment but I 
should be able to reproduce it if needed.

I was thinking tar could handle huge files which is what confuses me.

Kdar makes dar archives, not tar archives.

tar can handle single files of 8gb and archives of enourmous sizes.

Well, quoting a troll like fefe is not a good idea too. The page is full of 
nonsense. OK, it at least mentions a 21 GB tar archive but not a tar archive
with a 21 GB file inside.

The historic tar archive format supports single files up to 8 GB in tar 
archives. Since POSIX.1-2001, the extended tar archive format (called "pax")
has no size limitations.

Linux typically does not come with "tar" but with a tar clone called GNU tar 
that by default does not write standard compliant archives but it does not have 
a 4.7 GB limit.

Putting tar archives directly on CD/DVD media works, but it may confuse people.
When discussing the best way for putting large files on DVDs, you should take 
into account that people who insert a medium that does not get automounted 
typically believe that there is a problem with the medium.

This is why I added support for files > 4 GB to mkisofs.

How did you "add" support for that?  Are you talking about the program

Maybe it is more a problem of the specific fs, where you try to create 
it. If there the blocksize is to small (1024) then there is your 
problem.

What does dumpe2fs -h says about the blocksize of the specific device?

That's what you said earlier, but this time you said you were using kdar.
No, it's not dead. It was reported as such, but it is still in
development.

I thought that name looked familiar.  Some names are so close and I am 
awful at remembering names anyway.  Notice I mixed up Kdar and Kbackup? 

I was just wanting to make sure I had it set up on my rig correctly, now 
that we all know I am using Kbackup.

Last time I saw a reiserfs, that I needed to maitain was with SuSe 6.3, 
so I don't know if there could be a problem, but I kind of doubt that.

Everthing looks OK, but if there were more than 4 million files in that 
tarball, then you could run into trouble ;-)

Only thing, what comes in mind, is that the filesystem, where the 
tarball itself resides, has problems with files bigger than 2,2 GB and 
the tarball is currupt, because it was not copied completely.

And then my Latin is at the end

Kdar was masked, but not dar itself. Kdar was unmasked a few weeks later.

From http://bugs.gentoo.org/show_bug.cgi?id=216063

Kdar was given last rites and pronounced dead at 3/5/08. But in the
process of being wheeled down to the morgue for cremation it sat bolt
upright in the gurney and coughed. Scared the sh*t out of the poor nurse.

ROFLMAO.  I didn't know that.  I thought maybe something new was coming 
up for KDE 4 or something.  I lost my emails from the list about that 
time so I missed the scared nurse.  I did notice dar was still there 
tho.  Thing is, how you unpack that from say a Gentoo boot CD?  It's not 
exactly a tar file.  Seems you have to have dar/kdar to unpack the thing 
which would be useless for a system back-up.

I just wish I could have got that mondo-rescue thing to working.  It 
seems perfect for a system back-up.

It may not be on a Gentoo live CD, but it is on others, like
SystemRescueCD and (I think) Knoppix.

I got a Knoppix, sort of a old one but got one anyway.  May have to 
check and make sure it has dar on it.  Anyway, they all have the tar 
command.  ;-) 

I'm in the process of making a 4Gb tarball to see what that error was 
again.  Watch it work this time.  o_O

Here is my thoughts.  K3b seems to be using growisofs instead of the 
tools supplied by cdrtools.  Is there some way to "disable" growisofs or 
is there another way to do this? Here is what I have installed:

[I--] [  ] app-cdr/dvd+rw-tools-7.1 (0)
[I--] [  ] app-cdr/cdrdao-1.2.2-r2 (0)
[I--] [ ~] app-cdr/cdrtools-2.01.01_alpha41 (0)

Any other ideas are welcome as well. 

Thanks

I got it to burn.  It appears with all the unmerge/remerge stuff a 
setting got lost.  It just won't work with udf not checked.

Next issue.  Now that it is burned, it can't mount it.  Udf is in the 
kernel and it worked once before.  Another setting maybe?  Any other 
ideas?  Little info here:

root@smoker / # mount
<< SNIP >>
/dev/hdd on /media/hdd type udf (rw,noexec,nosuid,nodev)
root@smoker / # ls -al /media/hdd/
total 2
d--------- 2 root root  40 2008-07-06 22:55 .
drwxr-xr-x 5 root root 192 2008-07-06 01:55 ..
root@smoker / #

I am having trouble burning a 4Gb tarball at the moment.  Not sure what 
all the problem is but I had another DVD with one.  This is the command 
I use and the error less the looooooong list of files:

root@smoker / # tar -xvf /media/hdd/Data_2008.07.04-14.50.23_2.tar -C 
/backup/test/
data/Gentoo-stuff/livecd-i686-installer-2007.0.iso.bz2
tar: Skipping to next header
<<SNIP>>
tar: Error exit delayed from previous errors
root@smoker / #

ls of the file:

-r--r--r-- 1 root root 4295060992 2008-07-04 19:07 
Data_2008.07.04-14.50.23_2.tar

Any idea what that is all about?

There are many possible reasons:

1)	A well known bug in GNU tar (self incompatibility to
	GNU tar archives).

	I recommend you to use star to check the archive for correctness.

2)	You did not use a recent original mkisofs to create the image

3)	There is a bug in your Linux kernel.

You would first need to check with a tar implementation that is kown
to work (star).

Hi,

Sorry so long to reply but me and k3b have been having "discussions" 
about burning a huge DVD.  I emerged star but it may as well be Greek, 
no offense to the Greek.  Just something I will have to sit down and 
read sometime.

I got the DVD burned with a larger than 4Gb file.  Konqueror as a user 
says:  "Could not enter folder /media/hdd/" and I hear glass breaking.  
I assume that is not good.  Mount gives me this with regard to the DVD:

/dev/hdd on /media/hdd type udf (rw,noexec,nosuid,nodev)

I think this is a permissions issue.  Konqueror as root works just 
fine.  May need to beat on fstab or something with regards to that.  
More on that in a minute.

I can however access the DVD as root on the command line.  So, I just 
used tar and started to extract it.  It seems to be doing fine at the 
moment.  I will test further with larger files tho just to make sure.  
At least this time it unpacked the tarball with no errors.  After all, 
what's the point of back-ups if you can't unpack them? 

For the record, here is the current settings:

k3b:  under the burn screen I selected custom and then level 3 ISO, 
selected all file systems, preserve file permissions. 

Now back to the permissions issue.

fstab:

/dev/hdc              /media/hdc          iso9660         
noauto,users    0 0
/dev/hdd            /media/hdd        auto            noauto,users    0 0

Anybody see any reason why a non root user can't access the DVD?

I have set the permissions on /media/hdd to root/users with both having 
r/w access.  However after I insert a DVD, something changes it to this:

d---------  2 root root  116 2008-07-08 11:14 hdd

This is how I set it up:

drwxrwxr-x  2 root users  48 2008-07-04 14:21 hdd

It also changes back to my settings after I eject the DVD. 

I *think* I got the tar part working.  Any clues on the permissions 
issue?  Udev doing this?  I got something set wrong?

Thanks

Dale
