Many files are see so little traffic that mirroring them costs way too much. And now I'm really puzzled what your intention is - you strarted the thread with "remove all mirrors" and now you want even more stuff noone downloads?

[suse-mirror] Opensuse master rsync server performance

by Niklas Edmundsson

Related to the heads up about rolling updates for the upcoming release: Have you investigated speeding up your main rsync servers? ftp.acc.umu.se syncs from stage.opensuse.org, and we are seeing sync-times in excess of 24 hours at times. Sync-bandwidth on our end is limited to 1 Gbps, but the speeds we are getting are much lower so we suspect that the upstream server is the bottleneck. If you can't increase the performance of the main rsync server it might be beneficial to investigate a tiered approach where a few select primary high-bandwidth mirrors sync from the master site and the rest sync from the closest primary mirror. This is the way Debian has been doing it for quite some time with great success. /Nikke -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Niklas Edmundsson, Admin @ {acc,hpc2n}.umu.se | nikke(a)acc.umu.se --------------------------------------------------------------------------- I parked my harddisk - and got a ticket! =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[suse-mirror] Any reason why this list isn't listed on http://lists.opensuse.org ?

by Per Jessen

Just wondering - it isn't being archived either? Unless there is some specific reason, I'll go ahead and list it and have it archived. -- Per Jessen, Zürich (10.1°C) openSUSE mailing list admin -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[suse-mirror] IPv6 vs IPv4 performance for stage.opensuse.org

by Richard Brown

Dear Mirror hosts, Based on your reports I've been investigating the issues with IPv6 performance of stage.opensuse.org vs IPv4 I've been trying to confirm that we do have a problem with IPv6 specifically We know our bandwidth to stage.opensuse.org is suboptimal at the moment (6 days to go until we expect that to be alleviated) but in three sample sizes of ~5 minutes each during periods where our link seemed to be comfortable I've been able to come up with the current results IPv6 - 7.77MB/s | 14.41MB/s | 19.25MB/s IPv4 - 6.09MB/s | 10.09MB/s | 6.52MB/s This is from my personal host (rootco.de) hosted at hetzner These tests were conducted with the default recommended rsync string for all of our stage.o.o mirrors, with the addition of -4 for IPv4, -6 for IPv6, and --info=progress2 to get the average bandwidth calculation out of rsync. The general conclusion - At time of writing I can find no evidence that IPv6 is consistently worse than IPv4 for stage.o.o. It might even be better, though I'd want more thorough testing before making such claims. Obviously, I still think there is scope for different results from different hosts. Peering in particular could be different for IPv4 vs IPv6. If you notice different performance profiles for IPv4 vs IPv6 please report your findings, including source IP addresses and traceroutes. This information will be especially useful after March 1st, when we expect our routing to be significantly different than today. At time of writing, I can see no sign that anything needs to be changed on stage.opensuse.org or anything after the last hop. If the reported problems originate from congestion or peering, the changes to our link expected on March 1st will hopefully resolve them all, and if not we'll have to investigate and resolve with our new arrangements from then.

To satisfy my curiosity Carlos, can you double check and confirm you're using stage.o.o, and not rsync.o.o? Tim, as everything seems to be fine and fast for you, can you please consider changing your rsync module from opensuse-full to opensuse-full-with-factory? This will give us another Tumbleweed mirror in the UK, which we're quite short on at the moment.

Maybe we're mirroring a smaller set of > data? We mirror the same path, and see sync times all over the place. From 16 minutes and up, with a few hours being the most common one, and more than a day occasionally. Our sync-host is ipv6 enabled and comparing the RTT:s it seems like stage.opensuse.org is really bad at it. Running mtr -4t stage.opensuse.org and mtr -6t stage.opensuse.org simultaneously in different windows I see 45-ish ms RTT for IPv4 and 80-100ish ms RTT for IPv6. The difference is introduced in the last hop, so it's definitely bad mojo somewhere at or near stage.opensuse.org ... /Nikke -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Niklas Edmundsson, Admin @ {acc,hpc2n}.umu.se | nikke(a)acc.umu.se --------------------------------------------------------------------------- Many pages make a thick book. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[suse-mirror] NOTICE: Please Configure Your openSUSE Mirror Appropriately

by Richard Brown

Dear openSUSE Mirror Hosts, Thank you for your continued hosting of openSUSE Mirrors. While recently resolving an issue with rsync.opensuse.org we realised that a significant number of you are using rsync.opensuse.org as your content source. rsync.opensuse.org is meant to be a publicly available mirror host, but as registered hosts on this mailing list, you are entitled to use stage.opensuse.org, our dedicated mirror host for you. This server not only provides access to pre-release content, but is the authoritative source for all openSUSE content, including rsync.opensuse.org. As registered mirrors, please configure your sync cronjobs to use stage.opensuse.org instead of rsync.opensuse.org. This is particularly important for mirrors hosting openSUSE Tumbleweed (formerly known as Factory) which has a higher rate of change. While I'm mentioning Tumbleweed, if you are hosting a Tumbleweed mirror, please consider ensuring your sync cronjobs run more often than once every 24 hours. Also, if you are not running a Tumbleweed mirror, please consider altering your configuration to do so. Tumbleweed is more and more a key offering of the openSUSE Project and we really could benefit from more Tumbleweed mirrors. Compared to the "opensuse-full" module the addition of Tumbleweed will take approximately 60GB more disk space with an estimated rate of change of ~5GB per day (with a 'worst-case' rate of change being 60GB which occurs once or twice a year). You can achieve this by altering your sync cronjob to use the "opensuse-full-with-factory" rsync module. This request is part of an ongoing program of improvements including increased bandwidth for stage.opensuse.org expected on 1st March (doubling) & 1st June (4x more, 8x current) If you are experiencing problems with stage.opensuse.org performance, please let us know, especially after the above dates. Your ongoing feedback & support will help us shape and tune these improvements as we go forward. Many Thanks, -- Richard Brown openSUSE Chairman -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[suse-mirror] Leap 42.3 rolling

by Ludwig Nussel

Hi, Just a heads up. Leap 42.3 in opensuse/distribution/leap/42.3 is set up to be rolling during the development phase, similar to Tumbleweed. That means there's no 42.3-Current and no fixed milestones that get created from it. Instead we only have the 42.3 directory that gets regular updates when openQA says it's good enough. I'm hoping for increased attention and download numbers during development phase of course :-) cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[suse-mirror] wiki - mirror infrastructure

by Per Jessen

I was just looking into setting up a public mirror - https://en.opensuse.org/openSUSE:Mirror_infrastructure Some of this stuff is a bit odd. Look at section "rsync modules": > Sizes of the rsync modules are triangulated nightly: > > rsync modules of stage.opensuse.org > rsync modules of rsync.opensuse.org These both link to Peter Poeml's private site http://www.poeml.de/ and the sizes listed are incomplete. I guess we have these somewhere internally too? -- Per Jessen, Zürich (4.1°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org
