Mabinogi World Wiki:Wiki Server News/2011/Q3

From Mabinogi World Wiki

  • Unfortunately, the reprieve I saw would not last. This time, a kernel-bound LVM2 process caused all other processes subsequent to it to backlog, causing the machine to enter into a high-swap-use state and stay there, driving the load very high, up to about 800+. To assist in dealing with memory spurt usage, I have adjusted the point at which point it starts using swap. Hopefully, this will help with sudden memory use spikes. It appears the filesystem migration to stave this issue off was for naught, but some of the features of ext4fs made it desirable to migrate anyway, including checksummed journals. As such, the filesystem change will remain at present.

  • Rebooted the server to update the kernel to fix a serious problem.

  • Ninja update: Around the end of May or beginning of June, I added IPv6 support to the server and the site as a test for World IPv6 Day. The site continues to run with this support. Are you on an IPv6-capable connection? Give it a go! Please let us know of any issues. Rescinded for the time being due to below.

  • On Labor Day (September 5, 2011), the server had to be relocated very suddenly, giving me literally no notice to make a smooth transition for web to take place. However, thanks to Odin, at least word was gotten out about the state of the wiki. The server is now back at its original location in the datacenter in the northern part of the city of Fresno. Also, due to these circumstances, I have had to remove IPv6 support from the site. It should come back soonish, but there is no set timetable just yet. More information as it becomes available.
  • Removed GeoIP-based bans on the site in response to recent correspondence on the matter and given recent countermeasures enacted. More information can be found here.

  • On September 27, 2011, the server had to go down for about three hours due to a power bus upgrade in the cage where it is colocated. Original ETR was approximately half an hour but ended up being longer than that. However, I only had one hour's worth of notice. Despite the fact I had no easy way of getting the word out, I managed to shut the server down gracefully before the maintenance event began. The server now sits on a UPS which will supply power until a diesel generator comes online should any outage last longer than a few minutes.
