Greetings,

Is there a reason why there is a 3 GB barrier on persistence
with ext3?

Am I just banging my head trying to figure a way around it?

I'm guessing that the USB thumbdrives are formatted with vfat and that limits the max filesize?

TYL,

Hi Scott,

I wipe and reformat with ext3.

And it does sound like someone put an artificial 3 GB
barrier into it to accommodate max single file size
limitation of FAT.

With the following on a 16 GB ext3 stick:

livecd-iso-to-disk --overlay-size-mb 13287 Fedora-Live-Xfce-x86_64-21-5.iso /dev/sdc1

It will tell you the max "--overlay-size-mb" is 13287 if
you tell it something larger than it likes.

But, even when adjusted to make the stinker happy, you
still get 3 GB.

So, basically, is this a bug? And, has it been fixed
anywhere?

See this recent response,

It is important to understand that Fedora LiveCD technology is based on embedded filesystems,

an ext4 filesystem and partition (inside the ext3fs.img file) that is compressed inside a SquashFS

filesystem (inside the squashfs.img file) all saved on the LiveCD or .iso file in an ISO 9660 filesystem,

or on a LiveUSB device in the LiveOS folder of the device filesystem (which may be a fat, extX, or

other filesystem). With this technology, when one sees or thinks about a file or filesystem size, one

must be careful and clear about which of the many simultaneously present filesystems one is

referring to.
