I need help from someone experienced with the CentOS bug tracking system. I gotta say it is one of the most complicated and imposing front ends I've ever seen. Could anyone familiar with it please file a bug on my behalf? Particulars:
"CentOS 7.9.2009 DVD iso image too large"
ISO image: CentOS-7-x86_64-DVD-2009.iso 4.7GB raw CD image Wed Nov 4 05:37:25 2020 Burners: Both K3B and Brasero Media: Both DVD-R and DVD+R single-layer disks
iso image: 4,712,300,544 bytes User Anthony F McInerney advises Wikipedia says DVD-R capacity: 4,707,319,808 bytes (max)
I have tried burning this same iso image on two different machines: a CentOS 7.9 server and a Fedora 33 laptop. Same failure on both.
We need to ask the developers to make a re-spin that's about 5MB smaller. And before someone suggests it, the 2010-vintage server I'm trying to install CentOS on does not support booting from a thumb drive, so that option is not available.
Thanks,

Sounds like you need to use a dual layer DVD disc, it is double the capacity.

John,
Wrong answer. The server's optical drive doesn't support double-layer disks. The CentOS developers made a mistake on their DVD iso, and they need to fix it.

I don't think they have to do anything, who can tell them so they have to obey?
Why don't you try either CentOS-7-x86_64-Minimal-2009.iso or CentOS-7-x86_64-NetInstall-2009.iso? Both options should work for you.

Actually not -- the CentOS ISOs have not been meant for optical media since CentOS 6 -- they have been meant for thumb drives (>= 8G).
You are going to have to something different. Is it possible to do a network install on this machine. I believe the netboot ISO should be small enough to fit on a CD or DVD.

Exactly that. Upstream Fedora and RHEL went to require dual density around Fedora 18, RHEL-7 because the amount of data was too much. The CentOS developers have tried to their best to keep a single density working but there has been a constant race of problems with various 'important' packages having to be dropped from this ISO every time. For the final EL-7.x series, there were too many packages to do this with. The alternatives you have are:
1. Use CentOS-7.8 (or 7.7, or... ) as the boot media and then network update 2. Use CentOS-7.9 minimal and network update 3. Use CentOS-7.9 netiso and network install. 4. Use some mixture of the above with a USB disk of all the data and a kickstart to point to it so it gets there. 5. Look for a completely different alternative.
You are going to have to something different. Is it possible to do a network install on this machine. I believe the netboot ISO should be small enough to fit on a CD or DVD.

Sure, no problem. I had a similar problem with a different version of CentOS, 8.3, which is too large to fit on a dual-layer DVD. I also had a similar problem with another product altogether, pfSense, which will no longer fit on a CD, even though the docs said 'CD/DVD image' and I was trying to repurpose an old server, 64-bit capable but very early 64-bit, that had a CD drive (parallel ATA thinline!) with a special connector, and I didn't have a DVD drive available. Oddly enough, that old box can boot USB, but only certain sticks, and so I used an old 1GB stick to boot pfSense on that box. I was prepared to boot an older pfSense and upgrade up to current.....

What will it boot from? I do not use thumb drives. I have a USB interface to SD cards. Can you make the .iso file into a disk partition (not a file in it)? I've sometimes booted from one of those.

André,
I'm sure it would, but I thought I made it clear that DL or BluRay have never been options in this case. I'm disappointed that the DVD iso was released without any release notes advising it was oversized
I finally burned and used a network installation CD and NFS connected to a local mirror of the CentOS 7.9.2011 repository. That option will not be available to me in the future. I have the server in my physical possession for a very short while. After I finish installation and configuration, I will only have remote access.

To add to that: it would be unreasonable to expect from “binary replica” distribution to compose DVDs (or CDs) differently from upstream vendor. Therefore, media size may end up larger than limit.

There are environments where USB or other writeable media are not allowed on premises.
While all DVD-ROM drives are supposed to read DL media, in practice the compatibility has not proven to be 100%.

I think we are rabbit-holing on a bunch of related issues:
1. "How old hardware should be expected to work." Again this is not the core issue the original person was asking.
Upstream (RHEL) usually expects hardware that is confirmed to work to be usable through the release time. This hardware is usually on the year of release to 4 years afterwards. So RHEL-7 was released in 2014, so tested hardware configurations from 2014-2018 should work. Outside of that there are some work to make it work but the rules from online docs seem to be that if the hardware was from before 2012 and not a tested configuration, it should stick to RHEL-6. [This is mostly about a level of support that would be given point of view.. sure you could get it to work on a 2004 computer.. but if it breaks support is not going to spend hours/days/weeks trying to make it work. Consulting services are for that..]
CentOS has no support levels so if it works cool. if it doesn't then sorry. That goes for any dot release. If something is not caught in testing when various dot releases are being built.. that's too bad. [This isn't a new thing.. we didn't respin 5 releases when something wasn't caught until months later.] Also this is not really related to the original person's problem. It worked for them for many different releases and doesn't now.
2. "What are expected release results?" This is what the original question falls into. They have been running under the assumption that one set of DVD's would fall under a limit size for the single density drives. It has worked for multiple releases before 7.9 and then it didn't. However that expectation does not seem to have been in the testing procedures as a 'halt' level problem (i.e. measured in testing and then sent back if failed.) I will be honest on my part, I have only done a 'looks' good enough as I don't have single density DVD's to test if it worked or not. I use USB sticks and virtual machines. I am expecting the other testers to have done the same thing.
3. "What can be done". This is what the original question needs answered.
This was not caught in the release of 7.9 and that was a while ago. There are not going to be any more dot releases for 7.. there is no planned 7.10 so this is the final set of DVD's until 2024. At this moment, I don't know if a respin will make the images small enough and what would have to be dropped to make it fit. Respinning 'official images' now will also cause problems for a lot of mirrors and users who will ask 'did these images get hacked? why did it change now?' [And in either case, the original person needed this fixed yesterday, not in the 2+ weeks to do this.] I am guessing someone could make an unofficial set of spins which cut out some packages to try and make it fit in single density.

This is probably the solution at this point for the 'Full' DVD. In the interim, older machines such as this should just use the 'Minimal' DVD, since it fits on single-layer nicely. (I hear or read single-density and think FM encoding, 128 bytes per sector, 77-track IBM 3740 format 8 inch floppies......which are still in use in certain places...) Same for 8.x or 8 Stream -- oh, wait, there is no 'Minimal' ISO, so net install or USB is it, can't use optical media at all.
You're right; we're rabbit-holing. Being at a non-profit, I have to rabbit hole a lot, since I tend to use much older hardware than 'normal.'

https://mirrors.edge.kernel.org/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal...
There is a 7.9 minimal. There was no 8 minimal because composing is harder and the 'minimum' set of packages did not shave off a lot of disk space.
You're right; we're rabbit-holing. Being at a non-profit, I have to rabbit hole a lot, since I tend to use much older hardware than 'normal.'
Understood. This is where the modern OS assumptions of 'you should be in the cloud' and/or the 'your hardware must be only this old to be used' cause a hard fork with parts of the community.

I see at least two other possibilities, supergrub and making the .iso file into a partition. I've tried to boot fedora .iso partitions, both with and without success. That said, OP is using the netinstall version. I'd expect that to be more reiable than either of my suggestions. I'd have tried that before asking the list.

While all DVD-ROM drives are supposed to read DL media, in practice the compatibility has not proven to be 100%. _______________________________________________
You can safely assume that a DVD+/-R written to by an admin and read in by a DVD-ROM is a one-way vector at that data transmission level, with nothing beyond the bits happening.
If your USB ports are sealed with epoxy, USB is indeed not an option... and that's a feature, not a bug.

I need help from someone experienced with the CentOS bug tracking system. I gotta say it is one of the most complicated and imposing front ends I've ever seen. Could anyone familiar with it please file a bug on my behalf? Particulars:
"CentOS 7.9.2009 DVD iso image too large"
ISO image: CentOS-7-x86_64-DVD-2009.iso 4.7GB raw CD image Wed Nov 4 05:37:25 2020 Burners: Both K3B and Brasero Media: Both DVD-R and DVD+R single-layer disks
iso image: 4,712,300,544 bytes User Anthony F McInerney advises Wikipedia says DVD-R capacity: 4,707,319,808 bytes (max)
I have tried burning this same iso image on two different machines: a CentOS 7.9 server and a Fedora 33 laptop. Same failure on both.
We need to ask the developers to make a re-spin that's about 5MB smaller. And before someone suggests it, the 2010-vintage server I'm trying to install CentOS on does not support booting from a thumb drive, so that option is not available.
Thanks,

Guys ..
In order to do a full install set, we need a certain set of packages.
This set of packages is pretty much set in stone (you need all the deps to do every install in the comps set). I can not really adjust this package set unless we take some items off the installer.
This means that the DVD is indeed too big for some media.
If you are having issues and you HAVE to use a DVD and can not use a usb key .. please use the minimal ISO or the NetInstall ISO instead.
