Sometime, about a +year ago, that mirror disappeared. I had then contacted Switch to find +out what had happened (that was before the time of Mageia). + +The reply was that the usage of the Mandriva mirror had dropped to such +a low level, that Switch had decided to remove the mirror - the list of +software mirrored at Switch is quite remarkable, but without some +housekeeping the amount of mirrored data gets out of control. I had this +discussion with +Thomas Lenggenhager <<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">thomas.lenggenhager at switch.ch</A>> +(Thomas is the head of the group responsible for the mirror). + +Later, when Mageia had started to prepare its release, I had a +discussion with Christoph Graf - the vice-director for Network services +- and asked him about the policy of Switch with regards to adding a +mirror for a new Linux distribution - which, necessarily, starts from a +close-to-0 usage level. We agreed that Switch feels it its mission to +give new distributions a chance. At that time we did not press the +discussion further, waiting for the first Mageia (pre-)release to become +available. + +I agree with you that Switch is an ideal mirror for hosting a Mageia +mirror, I suggest you send the information pointed to by Michael to (but +only when information relative to item (5) of the howto exists - if +switch does not have the information how to register, chances are big +that the request ends up in some todo-sometime-later list) + +<A HREF="https://www.mageia.org/mailman/listinfo/mageia-discuss">netservices at switch.ch</A> + +I have read the howto at +<A HREF="http://distrib-coffee.ipsl.jussieu.fr/pub/linux/Mageia/mirror.readme">http://distrib-coffee.ipsl.jussieu.fr/pub/linux/Mageia/mirror.readme</A> +I have corrected some typos (it is a short document, I append the +corrected text to this mail). Regarding the objective contents, I have 3 +comments + +(1) is a 2-hour interval for syncing not exagerated? I think to remember +that with Mandriva there was one sync during the night; a longer period +reduces the load on the server, and reduces the periods during which +inconsistencies might be possible; probably a distinction between +cauldron (tier-1) and production (tier-2) requirements should be made +(coming back to Switch: Switch did not host cooker). + +(2) is it wise - at the tier-2 level - to suppress checksum protection? +I would say that with the relatively low number of tier-2 servers the +additional load on the server should not be prohibitive (particularly if +the interval of syncs is made longer). Mistakes due to transmision +errors at this level have a high multiplication rate and a substantial +nuissance potential - and certainly do not help to improve the image of +the distribution. Again, there is a difference in what is tolerable in a +development and in a production environment. + +(3) should the form not also specify the email and telephone number of a +contact person to be contacted in case of problems? + +Juergen + +----------- + __ __ _ +|<i> \/ | __ _ __ _ ___(_) __ _ +</I>|<i> |\/| |/ _` |/ _` |/ _ \ |/ _` | +</I>|<i> | | | (_| | (_| | __/ | (_| | +</I>|<i>_| |_|\__,_|\__, |\___|_|\__,_| +</I> |___/ + +This document describes the way to implement a Mageia Mirror. + +1) Prerequisite + +The expected size of the mirror is around 700GB. + +You need rsync software to synchronise the tree. + +2) Official source + +For public mirrors, we encourage you to use our Tier-1 mirror. + +This servers synchronises the tree directly from the Mageia rsync server + + o <A HREF="rsync://distrib-coffee.ipsl.jussieu.fr/mageia/">rsync://distrib-coffee.ipsl.jussieu.fr/mageia/</A> + located in Paris (France) + +3) Rsync options + +Ensure you're using at least these options: + + -a -H + +We appreciate if, in addition, you also add the options: + + --delete-after -S + +Don't use the compression and checksum options, they create excessive +load on the remote server + +4) Automated update procedure + +The tree must be synchronized at least every 2 hours. + +Please ensure that another rsync process is not started while a first +one is still running.
