Did you check the checksums?  Bad download?

Is the CentOS-7-x86_64-DVD-2009.iso really too big to burn on a DVD-R? Brasero under Centos 7.9 and Fedora 33 both say a 4.7GB blank disk isn't big enough.

Terry,

The checksums are perfect. What I am probably looking for is anyone who CAN burn that iso to a blank DVD-R or DVD+R. If Brasero won't do it, is it because the iso image is just every-so-slightly too large?

In this particular situation, dd-ing the image to an 8GB thumb drive is not a player because the target machine is a 2011 vintage Dell PowerEdge that does not support booting from thumb drives.

According to wikipedia DVD-R gets you the closest:  4,707,319,808   (MAX)

CentOS-7-x86_64-DVD-2009.iso  bytes: 4,712,300,544

It's only slightly over, it's possible that at least k3b and maybe xfburn supports 'overburn' . (I remember this more from the CD days than DVD though).

Otherwise I wonder if you could use 'ISO Master' and downsize it slightly.

Anthony,

THANK YOU. Yours is precisely the answer I was looking for. That iso file should never have been released as part of the general distribution.

I wonder how I could ask for that iso to be rebuilt to a size that fits on a blank DVD.

There is a program called "PlopBootmgr" that can be installed on a CD that will allow systems to boot from a usb drive that don't have that as a boot option.
