So.. I spent a bit more time investigating this. My initial numbers were off, but I do have tiles missing from Z11.
If my math is right, z11 should have 65636 meta files. I tried re-generating the tile set for that particular zoom level. I renamed dir 11 to move it aside, and requeued up Z11 to be rendered using render_all. I have renderd running as a service. It should be working fine, since that's how I generated the entire tile set initially. /usr/bin/render_list -v --all -n 4 --socket=/var/run/renderd/renderd.sock --min-zoom=11 --max-zoom=11 >& log.txt Now, despite the fact that I didn't see any errors in the log file. It didn't create any new files on the file system. Does it only render files past the last time it ran? Do I need to touch the planet-import-complete file? Or do anything special to reset the state back in time? -- Samir On Tue, Jun 22, 2010 at 4:42 PM, Jon Burgess <[email protected]> wrote: > On Tue, 2010-06-22 at 22:33 +0100, Jon Burgess wrote: >> On Tue, 2010-06-22 at 12:13 -0500, Samir Faci (Dev) wrote: >> > I'm in the process of updating a tile server switching from a Centos >> > with code/utils that are probably 6 months out of date maybe a bit >> > more, to a new lucid setup. >> > >> > Something similar to: >> > http://weait.com/content/build-your-own-openstreetmap-server >> > >> > Now, everything works fine, and I use renderd + render_list to >> > pre-generate a few zoom levels. >> > >> > The part that perplexes me is that it seems that that some of the >> > .meta files are missing, compared to the Centos machine. >> > >> > I pre-rendered 0-13 and on the Centos machine and it created: 3112877 >> > meta files.
