Hi Admins TL;DR: * provo-mirror.opensuse.org downtime 2020-06-05 until 2020-06-07 * 130.57.72.10 => 91.193.113.70 * 2620:113:8044:72:130:57:72:10 => deleted -- -- -- The public openSUSE servers in Provo, Utah will move into a new network and get new IPv4 addresses assigned as well during the first weekend in June: 2020-06-05 - 2020-06-07. There are currently no IPv6 (which is currently buggy anyway) addresses available in the new network. provo-mirror.opensuse.org is currently using: * 130.57.72.10 * 2620:113:8044:72:130:57:72:10 After the weekend, provo-mirror.opensuse.org will use: * 91.193.113.70 Please adjust your scripts or rsync module ACLs, if needed.

Re: Fwd: [mirror] Suboptimal (for mirrors) download pattern by opensuse clients
by Benjamin Zeller 03 Mar '20

03 Mar '20

Hi, Sorry for top posting but I just subscribed to this ML for this conversation. I'm currently working on the libzypp/zypper http/https media backend and have suspected something like that myself. Currently we do not download multiple files at once but download one file in multiple chunks. I have a new downloader implemented that would support multiple downloads in parallel but I suffer from the problem that mirrorbrains forwards me from HTTPS to HTTP if I disable the metalink downloads in favour of downloading full files only, curl errors out in that case. I know we could disable that error but I'm not really sure that this is what we want. With metalink files we get the metalink description over https , which includes all checksums for the several chunks and then can use http connections as well because we can check if we really got what we asked for. Would be interesting to know here if we can configure mirrorbrains to just redirect to HTTPS if that's what the incoming connection is using. Not sure if we could drop Metalinks completely, however it makes the code much more complex supporting it and if it actually does more harm then good we should think about something else. As to the suggestion to use dynamic or bigger chunks: The metalink description file we download at the beginning has the list of chunks included and they are fixed. We probably could try and download multiple chunks in the same request though.

[mirror] Suboptimal (for mirrors) download pattern by opensuse clients
by Niklas Edmundsson 21 Feb '20

21 Feb '20

Hi, am I the only mirror admin that finds the current behavior of opensuse clients suboptimal? Requests by "ZYpp 17.11.4 (curl 7.60.0) openSUSE-Leap-15.1-x86_64" etc seem to be done with 256 kb chunk size, always, as an example: GET bytes=0-262143 /mirror/opensuse.org/tumbleweed/repo/oss/x86_64/libqt5-qtwebengine-5.14.1-1.5.x86_64.rpm GET bytes=262144-524287 /mirror/opensuse.org/tumbleweed/repo/oss/x86_64/libqt5-qtwebengine-5.14.1-1.5.x86_64.rpm That's a silly small size, since TCP won't be able to ramp window sizes and get good speed before those 256k are done. Also, we get int($filesize/256k) entries in our logs for each download. To make matters worse, the thing seems to do some kind of round robin between sites, with this pattern being the most ineffective looking from a mirror admin standpoint: GET bytes=2097152-2359295 /mirror/opensuse.org/tumbleweed/repo/oss/x86_64/libqt5-qtwebengine-5.14.1-1.5.x86_64.rpm GET bytes=2621440-2883583 /mirror/opensuse.org/tumbleweed/repo/oss/x86_64/libqt5-qtwebengine-5.14.1-1.5.x86_64.rpm Since the OS normally does read-ahead on file system reads, it will read-ahead after byte 2359295 in preparation for the next read(). In this case though, that's in vain as the request never comes but the next data read is instead byte 2621440 and forward... OS read-ahead is most commonly in the 64kB-1MB range, so it's not unlikely that the entire 256k gap inbetween is read from disk without being used... Downloading files this way is just plain stupid, IMHO. I don't know what problem this behavior is supposed so solve, but it's definitely not beneficial for us as a mirror, and I think it's hurting your end users as well. If you want more bandwidth from us, request larger chunks (or whole files). The TCP window will grow and you'll get the performance (within the limits of 10 gigabit networking for one download). If you want to spread the load between mirrors, use larger chunks, and specifically avoid small chunks and striped access. In any case, merge requests! If you're going to request a number of consecutive chunks, do it in one request, preferrably as one range, to make the most of the tcp connection you've set up. My minimum suggestion would be to bump the chunk-size to multiple megabytes at the minimum, possibly varying depending on download performance, aiming for each GET taking at least a couple of seconds to allow for TCP to ramp speed (and reduce the noise in our logs). In extreme cases we're seeing multiple tens of GET:s each second for some downloads, I'm guessing the rate throttles due to the RTT latency (ping time) and not some real bandwidth limit... /Nikke - admin of ftp.acc.umu.se -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Niklas Edmundsson, Admin @ {acc,hpc2n}.umu.se | nikke(a)acc.umu.se --------------------------------------------------------------------------- NOW (n), adv: A moment in time that has already passed. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[mirror] openSuSE mirror problem
by ariel sabiguero yawelak 04 Dec '19

04 Dec '19

Hello. We had some trouble with one F.O. link to our faculty, thus, we had to "move" our mirror (espejito.fder.edu.uy) to a new IP address: 164.73.178.222 from a different provider. The provider states that the problem would be solved by 9th dec. As soon as it is fixed, we will return to previous operation conditions. Please let us know if there are further inconvinients or problems caused by this issue. regards ariel -- To unsubscribe, e-mail: mirror+unsubscribe(a)opensuse.org To contact the owner, email: mirror+owner(a)opensuse.org

[mirror] packages builds not propagating to mirrors again -- for several days?
by PGNet Dev 11 Jul '19

11 Jul '19

My OBS kernel build's been through a couple of build cycles over the past few days. Currently, successfully built packages are not propagating to the mirrors; this is unfortunately a not-uncommon result, often going on for days. No idea what the actual problem is. What needs to be done to get propagation working consistently? E.g., this https://download.opensuse.org/repositories/home:/pgnd:/Kernel:/stable/openS… Mirrors for kernel-default-5.2.0-29.1.g7501499.x86_64.rpm File information Filename: kernel-default-5.2.0-29.1.g7501499.x86_64.rpm Path: /repositories/home:/pgnd:/Kernel:/stable/openSUSE_Leap_15.1/x86_64/kernel-default-5.2.0-29.1.g7501499.x86_64.rpm Size: 67M (70770360 bytes) Last modified: Wed, 10 Jul 2019 11:03:04 GMT (Unix time: 1562756584) Download file from preferred mirror Reliable downloads Metalink /repositories/home:/pgnd:/Kernel:/stable/openSUSE_Leap_15.1/x86_64/kernel-default-5.2.0-29.1.g7501499.x86_64.rpm.meta4 (IETF Metalink) /repositories/home:/pgnd:/Kernel:/stable/openSUSE_Leap_15.1/x86_64/kernel-default-5.2.0-29.1.g7501499.x86_64.rpm.metalink (old (v3) Metalink) Mirrors List of best mirrors for IP address 99.xx.xx.xx, located at 36.270241,-121.8074545 in United States (US).

[mirror] openSUSE Leap 15.1 on the way
by Ludwig Nussel 17 May '19

17 May '19

Hi, openSUSE Leap 15.1 is on the way to your servers! Release date is Wednesday 22nd 12:00 UTC. As usual access to iso images is limited until then. stage mirrors should be able to pull the iso nevertheless (and keep the restricted permission). So maybe a good chance to check your setup so it's ready for Wednesday. 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

[mirror] Connection issues?

Hi all, since around Friday our mirror has some issues connecting to the master: rsync: failed to connect to stage.opensuse.org (195.135.221.130): Connection refused (111) Is there something wrong with the server or should I have a look on our end of the cable?
