[Qemu-devel] LBA48

Hi,

I tried to use QEMU with a 1Tb qcow disk image, but it doesn't work  
as expected.
Linux informs
"
hda: cannot use LBA48 - full capacity 2147483648 sectors (1099511 MB)
hda: 268435456 sectors (137438 MB) w/256KiB Cache, CHS=65535/16/63
"

Can anyone implement LBA48 in QEMU please?

Regards,
Natalia Portillo

I'm not sure, but I think the issue is: which file system do u have in
your host? I think that at least 1 filesystem doesn't support
creation/access of terabyte file sizes.

You might want to try with filesystems like XFS, JFS or the latest ReiserFS.

Thanks,
Hetz

It has nothing to do with the host filesystem, because, as you see,  
the kernel detects that the disk is 1Tb but is unable to handle it  
because LBA48 is not available.

Apart from that I used qcow for the image (so it ocuppies 4Mb  
actually without nothing wrote on it), in NTFS host (up to 2Tb file  
size in current implementation, 16Eb as specification says),  
compressed (so it will never ocuppy 1Tb).

Sounds easy enough. Can you send me a spec?

This made me laugh... (no flames, please)

Person1: "Can you do some work for me for free?"

Person2: "Sure, where's the documentation?"

Person1: "Here it is... it costs $18."

Happy New Year Everyone!

That link didn't work for me, found a couple of more links here:

    http://home.teleport.com/~brainy/diskaccess.htm

specifically,

      http://www.t13.org/docs2004/D1572r2a-EDD3.pdf
 or
      http://www.t13.org/docs2004/D1572r2a-EDD3.doc

It appears as if Dave Burton is to be thanked for that information. 
Thanks Dave!

Great document except because OSes (but DOS, so on) won't use BIOS  
but direct IDE (through IRQs 14 and 15 and their I/O ports) or PIIX,  
and that is what is needed to be expanded first (as BIOS will use them).

So, ATA-6 specification is still needed.
