Hi Lance,

I've completed mirroring the DVD images, and am willing to give it a try. mirror.averse.net / mirror.spanasia.net (interchangeable)

http://mirror.averse.net/centos ftp://mirror.averse.net/pub/centos rsync://mirror.averse.net/centos rsync://mirror.averse.net/centos-incdvd

I'd suggest that it's useful for separate and obvious rsync targets to be made available; it'd suck for someone downstream to switch from one mirror to another, only to find his existing DVD images wiped out. It's not hard to create a new rsync target with "exclude = *DVD.iso" or "exclude = isos-dvd/"

I see what you mean - and think I agree with you :)

By the same token someone who switches to a mirror with dvd's that didnt have them will get an extra 25 GB they didnt expect.

The latter is preferable as there are also *dvd.iso to consider.

The issue now is that we will need to get existing dvd mirrors to comply ....

Guys - any chance ....

Or do people not agree ....

Due to unknowns trying to download dvd.iso images from our msync-dvd servers we have now had to restrict the rsync target to those mirrors that we know are syncing.

We want to restrict it further to those that are providing master sync service for other mirrors, this will allow us to plan for future releases to be able to preset the dvd isos onto those master mirrors before release and dedicate bandwidth for that.

The current mirrors that are allowed to sync by the config are :-

   #pacific.net.au         61.8.0.17
   #kernel.org             204.152.191.4 204.152.191.36
   #upce.cz                195.113.124.9
   #mirrorservice.org      212.219.56.140
   #esslingen.de           129.143.116.10
   #ncnu.edu.tw            163.22.12.51
   #vutbr.cz               147.229.176.19
   #ftp.chg.ru             193.233.9.194

Of those only 4 - kernel.org, mirrorservice.org, esslingen.de and chg.ru have told us that they allow rsync, which has to be a prerequisite for being a master sync mirror.

If any of those are not happy to be listed as a master sync mirror for the dvd isos , or have limits on bandwidth or resources that may be affected then please advise us.

We would be grateful if the others would change their config to sync the dvd iso images from one of those, which will probably provide faster download than our servers anyway.

We will start to list all mirrors that carry dvd iso images on the website and will shortly redirect browsing on mirror.centos.org to those local mirrors that have the dvd isos and are up to date, as we do for cd isos. The main difference is that we will only check currency of mirrors that are flagged in the database as carrying dvds.

We do still need more master sync mirrors but you will not be able to sync the target without first notifying us (or do initial sync against one of the sync masters and then request access - as we would prefer sync masters to eventually sync directly from our servers).

In particular csmb.edu has said that they will be a master sync mirror but does not appear to be syncing the incdvd target.
