I tried to build a tile server (see https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/)

Unfortunately, tiles with a low zoom level are not rendering. The DONE TILE is missing. What can be the reason for that???

These don't work:

http://xyz/hot/1/0/0.png
http://xyz/hot/2/0/0.png
http://xyz/hot/3/0/0.png
http://xyz/hot/4/0/0.png

It works from zoom level 5:

http://xyz/hot/6/0/0.png

etc...

Here is the output of renderd -f -c /usr/local/etc/renderd.conf

For info what you should see is something like:

Not sure why you're not getting that. I can only suggest (a) installing the missing fonts and trying again and (b) rechecking the particular contents of lower zoom levels (maybe some shape files aren't accessible)?

Thank you for your suggestions. I've installed the OSM server again as described in https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/ Unfortunately, it's not working. Had the same problem again. Does anyone has any suggestions? I don't get any helpful error messages.

How long are you waiting for completion?

Low zoom tiles can take a significant amount of time to render (particularly if you are doing this on the full planet) and you should not dynamically (aka on-demand) render them. Use render-list to pre-render, see the text at the end of https://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/

It's a possibility, but the reason why I suspect it's not "low zooms take a long time" is that z0 is normally pretty quick. Here's a quick test:

Dec 21 20:50:40 ubuntuvm40 renderd[1606]: DEBUG: START TILE ajt 0 0-0 0-0, age 60.41 days
Dec 21 20:51:38 ubuntuvm40 renderd[1606]: DEBUG: DONE TILE ajt 0 0-0 0-0 in 57.526 seconds

that's on a VM on a cheap desktop PC that's actually very busy with a minutely update.

Yeah put is that the HOT style? osm-carto uses a reduced data set at low zooms, iirc (HOT layer currently seems to be broken) the hOT style has a lot more going on at low zooms.

(21 Dec '17, 21:02) SimonPoole ♦

It's actually https://github.com/SomeoneElseOSM/openstreetmap-carto-AJT , which makes use of shapefiles of non-OSM data at low zooms (OSM Carto uses shapefiles of OSM data now as I understand it). OSM Carto takes 3 times as long to process by "carto" as my style, but doesn't seem to take longer to render - at least zooms from 8 or so up (can't say I've tested <8 for a while, but don't remember a specific problem).

Thank you for the comments. I've used render-list to pre-render tiles at low zoom levels and it's working now.
