Space available 8GB USB Device

[Cadu]

Hi guys!

I'm having problems of space when i try add more packages in live image.

I'm using the command:
livecd-iso-to-disk-oc --noverify --home-size-mb 2048 --overlay-size-mb 2048
${ISO} ${LOOP}

*


getdisk DEV = /dev/loop2
Unable to fit live image + overlay on available space on USB
stick
+ Size of live image:  2986
+ Overlay size:  2048
+ Home overlay size:  2048
---------------------------
= Requested:  7082- Available:  7075
---------------------------
= To fit, free or decrease requested size total by:  7
Cleaning up to exit...*
*


*


My question is: Which parameter can set the total space of my 8G pendrive?
Why the space is limited in 7075?


Thanks a lot!

With Ext2/Ext3 there is a percentage of disk space that is reserved.
I am not sure what the default is but you can google ext3 reserved
space to determine why and how to set it to zero.   The remainder is
probably just the different calculations used by the manufacturer.

The available disc space is calculated at these lines in the current
version of livecd-iso-to-disk script,
http://git.fedorahosted.org/git/?p=livecd;a=blob;f=tools/livecd-iso-to-di...
using the df command.

(The livecd-iso-to-disk-oc name and output indicate that you are using an
older version, but the process is similar.)
Other files on the drive and the specific filesystem formatting type and
configuration will affect the results of df.

The 8G advertised by the vendor is 8*10^9 bytes. I believe the sizes
above are in MiB (2^20 bytes). 8GB is only 7629 MiB. Then as mentioned
previously, a chunk of that needs to be used for file system overhead.
