Hmm... ok this explains why I couldn't find Wikipedia Zero-related memcache entries when testing from fenari last night. :( It sounds like maintenance scripts could have a serious split-brain problem if they're being run in pmtpa while the web servers are in eqiad, if each cluster uses its own local memcached servers. Either updates need to be proxied to both clusters (race conditions?) or it should only be possible to run maintenance scripts in the same cluster that's running the web servers. The former sounds scary and latency-intense, while the latter requires more configuration on the eqiad bastion hosts so MW scripts can be run. :( -- brion _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
