Thanks for everyone's patience! The wiki is now back online. There may be a few missing images that we still need to track down and reassociate out of the lost+found directory, but the database (text content) and the overwhelming majority of images are intact.

Just a quick post trauma debrief:

The file system became pretty munged. This rendered the server unbootable. We were able to run an fsck to bring the file system back into consistency, but a lot of system files ended up in /lost+found and the machine was still entirely unbootable. We had backups of course, but not current to the second of the disaster and we didn't want to lose any of the latest wiki changes if possible. So we snagged a remote copy of everything on the hard drive. Then we proceeded to start from scratch (forced into this because the original disk became unbootable.) Simon reinstalled all the proper versions of the wiki software and friends. He also setup the email server and configuration (the wiki uses email to communicate with users at times.) We restored the mysql database, and then proceeded to restore all the wiki image and data files. The restore process took some time because not all of us are as well connected to the internet as we'd like to be. Finally, Simon and Gijs did some work to try to find and pull lost images and files out /lost+found and get them back where they were supposed to go. The end result is I think we are 99.9% there with a chance of a few missing images here and there. If you find something missing, feel free to report it and we can try to track it down one way or another. Simon has setup a directory with some of the missing images, although not a convenient way to browse them at the moment. You can browse through the orphan media files here if you care curious: http://wiki.flightgear.org/images_found/

Thanks again for everyone's kind patience ... sometimes things just take a little time in volunteer land.

Curt.

I found some images in the "orphan media files" that are being used on a current wiki page. They are working and available on that page but it seems they have been duplicated several times in the "orphan media files"?
How do you want me to this handle this?

I also have located a few missing images in a wiki article. Would you prefer I upload new image (if available) to the article and give you the name of the originals that are in the "orphan media files" to be deleted. Or is it easier for you to reattach them from orphaned to the wiki article?

I believe many of these files come out of the thumbnail directory. I believe the wiki creates multiple versions of each image at different resolutions to save bandwidth when serving the files out. If you can give me the name of a file and the original path ... something like http://wiki.flightgear.org/...something ... lename.ext then I can hunt for the filename in lost+found and in many cases move an entire directory of images (maybe a dozen or more) back to their correct locations.

that is correct - but I think those thumbnails should be re-created automatically - for instance, the png folder contains a few MapStructure PNGs:

However, the restored wiki displays those thumbnails properly, apparently even without those files having been manually moved: http://wiki.flightgear.org/Canvas_MapStructure

No big deal here as this pertains to my user page. If easy enough to correct go ahead, if not let me know and I'll just edit it.

all of these images are in http://wiki.flightgear.org/images_found/jpg/

This group I think is just thumbnail
Code: Select all

960px-Kansas_Scenery_Four.jpg                      26-Jan-2015 13:35               57527



these three appear on the wiki page correctly, so I don't know what these were for.

these two below are missing from the page http://wiki.flightgear.org/User:Wlbragg

Looks like some of the images are too big and covering some of the written content of the page.

I don't see that on my system, in fact if I shrink the browser window the text just shifts and adjusts to fit.

what you are referring to is unrelated to the recent wiki downtime - wiki formatting is fairly flexible, but many articles don't make use of advanced formatting - so what you are describing can be seen in quite a few places/articles. To be on the safe side, you should tell us exactly what article/images you are referring to - otherwise, this won't be helpful I'm afraid.

Should I set up a wiki page, for example FlightGear wiki:Missing files where we could post links to missing images?

If so, in what way would you guys prefer the URLs? In what format would they be most helpful and give you less work? Would it be like File:TWR-View LIPA Winter.JPG, Images/f/ff/TWR-View LIPA Winter.JPG or something else?

Re: wiki.flightgear.org scheduled downtime

Hello
At first when the wiki came back everything seemed to be OK on the http://wiki.flightgear.org/Eurocopter_EC130_B4 page.
Now I noticed several EC130 files are listed on the http://wiki.flightgear.org/images_found/jpg/

Today I got an error about creating a Thumbnail with file missing, but the issue seems to be naming conventions with " " and "_".
e.g. the jpg http://wiki.flightgear.org/File:EC130-B ... ox-012.jpg is there, but the thumbnail can't be created.

No problem for me to correct this I think, but a bit disturbing that things seem to change from day to day ?

Hi Mike,

we updated the MediaWiki software yesterday and had to make some adjustments to the server configuration for that. The issue here is that the image file definitely isn't there. Only some of the thumbnail versions are. The MediaWiki update changed the default thumbnail size, hence it tried to recreate thumbnails. But we canot create new thumbnail versions, because the original image is no longer where it's supposed to be (that's the error you're seeing). Have you identified which one it is in the images_found directory?

Please don't re-upload the image or try to fix it yourself (you cannot). We'd like to find out if we can restore those images in batch once we've found some pattern.

Cheers,
Gijs
