[CentOS-mirror] Status of dvd iso for CentOS mirrors.

With the release of 5 we have seen a tremendous increase in the use of the 
dvd.iso , so that from bitorrent it is now downloaded 5 times more than 
the cd isos.

That may be due in part to it being hard to find and more readily 
available by Bt, but I think is also down to increased prevalance of 
dvd-rom drives.

The main issue with having the dvd isos available from mirrors is that
Apache < 2.2 running on 32 bit architecture wont display files larger 
than 2.0 GB , however CentOS 5 has Apache 2.2 with large file support so 
that problem will now start to go away - alternative is also to use 

(CentOS now has its first server up running C5 and able to display 
large dvd images under http :)

I have updated our isoredirect system to detect and verify dvd isos on 
mirrors , and sources with current dvd isos are now listed separately on 
the isoredirect page - what this is showing is that very few of our 
mirrors have the dvd isos and we need to get more out there ...

To test :-

It will give you local info based on your ip
you can also add &cc=xx to test other country codes

I know a lot of mirrors are wanting to download the dvd isos and we have 
just configured two new servers with msync-incdvd.

However, we would still like mirrors to do their initial sync of the dvd 
isos to one of our tier 1 mirrors that have them , and then we will add 
their ip addres to our acl for syncing.

We also have no problem if mirrors want to sync to a local tier 1 mirror, 
our system will still detect that they are up to date.

It is likely that in the near future we will restrict access to msync 
rsync to current registered mirrors, and new mirrors will either have to 
register first or do an initial sync from a registered mirror *hmm - we 
have said this before - but now we have 160 mirrors we really will have to 
do something ...)

There has been some confusion about the CentOS and CentOS-incdvd rsync 
targets , and the fact that some mirrors have dvd isos included in the 
CentOS target, so what we would like to do is to have a list of tier 1 
mirrors that :-

1. provide rsync access to the complete CentOS release tree
2. would be prepared to act as a seed for new mirrors
3. would be prepared to set up separate CentOS and CentOS-incdvd targets 
for other mirrors to sync against, either initial or recurring syncs (the 
trees would be hardlinked, so extra space required is minimal).

We will then publish details for other and new mirrors of how they can 
sync against these master sync servers.

If you would be prepared for your mirror to act as one, and have the 
bandwidth and capacity for it then please respond.

Whilst writing I would like to thank all of our mirrors for the tremendous 
support that you provide for CentOS and our users and especially during 
the release of 5.0
