CentOS 7 EOL and end of (legacy) mirror network
by Fabian Arrotin 20 Jun '24

20 Jun '24

Hi all As reflected some time ago on the ticket tracker, we weren't adding any 'legacy' mirror to mirrolist.centos.org (nor mirror-status.centos.org) as content moved to different mirror network , starting from CentOS Sream 9 (mirror.centos.org vs mirror.stream.centos.org) As you know, that means that there was a different ticket for Stream 9 (and now 10) content, and interested mirror admin[s] needed to self-register their stream mirror on mirrormanager.fedoraproject.org and then create specific ticket on infra tracker to ask ACL to be modified (https://pagure.io/centos-infra/new_issue/?template=mirror-request) CentOS Stream 8 went EOL last month and CentOS Linux 7 itself will be EOL end of June, meaning that all content from mirror.centos.org will also disappear. Same for mirrorlist.centos.org service, as not used anymore for any supported centos version (stream 9 and 10 are served from Fedora mirrormanager infra) That means that all mirrors entered into (legacy now) mirror crawler (and reflected on https://mirror-status.centos.org) will not be verified/crawled anymore either. Worth knowing that for some time the msync.centos.org::CentOS rsync service will continue to be available but all content will be removed (automatically cleaning up disk space on downstream mirrors too) Thanks a lot for having been part of the successful mirror network since the beginning of the project ! PS: if you're interested in mirror Stream content, feel free to have a look at https://wiki.centos.org/HowTos(2f)CreatePublicMirrors.html#CentOS_Stream_9 -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

Adding ACL for rsync.stream.centos.org (like we always did for msync.centos.org)
by Fabian Arrotin 13 Dec '22

13 Dec '22

Just this little mail to announce that we have now put in place the same mechanism to only allow registered third-party mirrors to pull/rsync from us. (ticket https://pagure.io/centos-infra/issue/999) Due to lack of bandwidth/resources and also sponsored nodes disappearing (and so remaining sponsored infra being overloaded with requests), we had to adapt the process to also have ACL in place for CentOS Stream 9 (as it was already documented for years on https://wiki.centos.org/HowTos/CreatePublicMirrors) to only allow ip address[es] (ipv4 and ipv6) from these registered mirrors (https://pagure.io/centos-infra/issues?status=Closed&tags=mirrormanager&clos…) Should you suddenly be blocked (because you are now using a different ip that differs from the one you added in your initial ticket on centos-infra tracker), feel free to create ticket to request the ip to be updated in our ACL.

Spring Clean-up (aka removing dead mirrors from crawler/lists)
by Fabian Arrotin 14 Apr '20

14 Apr '20

Hi all, When having a look at https://mirror-status.centos.org, I saw that we had quite some mirrors that don't seem to be monitored (despite previous mail sent to PoC) and in bad shape (not reachable or really outdated). Those mirrors are automatically removed from yum/dnf produced lists, but still eats time at the crawler process level when trying to validate/reach out those mirrors. For that reason, I so disabled those mirrors in our DB and such nodes are so gone from https://mirror-status.centos.org/ (which is so now in "good shape") In case your mirror would be impacted (but weren't paying attention to previous mails nor your own monitoring for your pull script), you can still reply on the centos-mirror list *after* you have verified what was wrong and how you fixed it. Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

Deprecating previous eu-msync/us-msync A/AAAA records
by Fabian Arrotin 25 Mar '19

25 Mar '19

Hi, While we already implemented that change a long time ago, it seems that (based on discussions I had with Anssi), some people are still using eu-msync.centos.org or us-msync.centos.org as hostnames in their scripts (and sometimes using one as fall back of the other one) That doesn't make sense anymore as those records were switched some time ago to be CNAME of just msync.centos.org : dig +short +noshort eu-msync.centos.org eu-msync.centos.org. 600 IN CNAME msync.centos.org. dig +short +noshort us-msync.centos.org us-msync.centos.org. 600 IN CNAME msync.centos.org. msync.centos.org is itself delegated to our PDNS setup, using GeoIP, that will answer A/AAAA record (from a validated list of nodes in the msync pool) based on your location. As said, that was already updated a long time ago, but it seems I forgot to send the announce email for this (even if all continued to work, with the CNAME setup, and we'll still keep those, in case people don't read this list, and so are still using those names to sync from) Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

CentOS 6.8 release and mirror status
by Fabian Arrotin 25 May '16

25 May '16

Hi Mirrors Admins, As you probably know, CentOS 6.8 is now built. So expect to see some traffic when it will be released - very soon - (when the whole tree/isos will land on your mirror, and when people will then start downloading/rsyncing from your mirror). Just to let you know also that expected size is ~31Gb. After some time we'll remove the 6.7 folder and will archive it to vault.centos.org, so you'll get back that space. If you have questions, feel free to discuss that on the centos-mirror list, or in #centos-mirror, on irc.freenode.net Kind Regards, -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

[infra] : availability of msync.centos.org over IPv6 (please read)
by Fabian Arrotin 24 May '16

24 May '16

Dear Mirrors Admins, Recently we worked with the various sponsors hosting nodes for our msync network, and we were able to have enough IPv6 connectivity to publicly announce the availability of msync.centos.oorg over IPv6. Actually we have ~50% ipv6 coverage in the msync network to open it up to you. What does that mean ? if you have native ipv6 connectivity, you'll be able to automatically sync from us over ipv6 instead of ipv4, using the same rsync url ( msync.centos.org::CentOS/ - see https://wiki.centos.org/HowTos/CreatePublicMirrors) We decided to make it transparent, so we just added AAAA record[s] in our GeoIP pdns backend for msync.centos.org. Worth knowing that we're still using the same rsync target as before, and so also doing IP check for incoming connections (see initial announce mail for this : https://lists.centos.org/pipermail/centos-mirror-announce/2014-June/000015.…) This so remains in place but we'll add ipv6 addresses in the same ACL (already working and confirmed by some testers on the centos-mirror list,or #centos-mirror) What do you have to do ? normally nothing as if you advertise AAAA record for your public mirror, we have added it in the ACL already (and instead of just adding it, we added the whole /48 subnet around it, in case you're using a different IPv6 address for the outgoing connection) What if it doesn't work anymore ? feel free to answer to that thread (on the centos-mirror list only, not on the moderated centos-mirror-announce list) or reach us in #centos-mirror on irc.freenode.net and we'll verify your IPv6 address/subnet block in the ACL. What if you have IPv6 but still want to enforce rsync over IPv4 ? you can just do that at the rsync level through the "-4" parameter (man rsync) Should you encounter an issue, or should you have questions, feel free to reach us directly. -- on behalf of the CentOS sysadmin/infra team, Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab

CentOS-6.7 RPMs and drpms added to 6.6/cr
by Johnny Hughes 26 Jul '15

26 Jul '15

I have just pushed the RPMs and drpms to 6.6/cr/ repo. In 45 or so minutes, all the msync mirrors should have content. I will push the repodata tomorrow at around 1000 UTC. This should allow a better experience for users as external mirrors can get the repodata tomorrow much faster than the whole set. The package set is about 7GB. Thanks, Johnny Hughes
