Thinking Sphinx not indexing certain models

This is quite strange. I have 3 models (A, B, C). Were working perfectly when crontab runs it.

Recently, I was having problem with indexing new entries for model A.

When I invoke rake ts:index RAILS_ENV=production manually, indexing runs fine. No error, problem. But, only model B, C get updated. Model A doesn't get updated. I checked all the logs, there wasn't any problem.

Here's searchd.log:

[Mon Nov 29 15:02:27.920 2010] [ 7280] rotating indices (seamless=1)
[Mon Nov 29 15:02:28.211 2010] [ 7280] rotating index 'b_core': success
[Mon Nov 29 15:开发者_运维问答02:28.215 2010] [ 7280] rotating index 'c_core': success
[Mon Nov 29 15:02:28.216 2010] [ 7280] rotating finished

Here you will notice a_core doesn't appear. All these while it was working fine. When I saw it running, it was indexing A, but when I checked my sphinx db when it was last updated, it was not updated. Permission for all Sphinx db is all the same.

The only way to get the indexing running well is to remove old sphinx db, and invoke an entire ts:rebuild. I haven't tried removing the production.sphinx.conf though.

I did try to add delta indexing in the past before this happened. Well, delta indexing couldn't work somehow, but the normal indexing was fine. Then, the indexing broke for model A. I didn't realize it broke anyway. Then I turned off delta indexing without removing the column. (I still didn't know indexing was running fine for model A). Then today I found out there was problem with model A indexing. So I thought maybe I didn't remove the delta column in my database. So I removed the column, restarted MySQL, Apache, and model A index still doesn't get updated.

I actually don't think it has something to do with delta indexing. Because I added, then removed delta indexing for all A, B, C models. If it should break, it should break all instead of just one model.

Please help. Thank you.

EDIT Model A

  # ThinkingSphinx Index
  define_index do
    indexes :name, :sortable => true
    indexes address
    indexes city
    indexes state
    indexes country
    indexes spot_type
    indexes season
    indexes description
    has rating_average

  #  set_property :delta => true
  end

Model B

  # ThinkingSphinx Index
  define_index do
    indexes name
    indexes duration
    has budget, created_at, rating_average

  #  set_property :delta => true
  end

It turned out, my server ran out of disk space. Model A index is very much larger than other models. Even though indexing was successful, it couldn't write to the disk (though there was no error ouput). But as I kept trying to add more and more contents to model A, and kept rebuilding, the disk space problem showed.

So I increased my disk size. Now it's fine.
