File cache_form.MYD filling up a partition on magon.

Reported by: Enrique Rosas Owned by: Jamie McClelland

Keywords: drupal cache_form.MYD cache Cc: marvin@…, apolination@…
Sensitive: no


Hi Dana, After Ross warned us about this partititon being filled up, we found this file to be the reason of the issue: cache_form.MYD, which is part of a drupal database.

0 magon:~# ls -lhaS /var/lib/mysql/ctamlibre_oa_db|head -n 2
total 3.0G
-rw-rw---- 1 mysql mysql 3.0G Nov  6 14:52 cache_form.MYD
0 magon:~#

with mysql I found it had 167 rows. I wonder what could had being inside that table to height that much?

After running "Clear all cache" (Limpiar los datos de la cache, in the spanish version) now the file has only 6 rows, but the operating system does no recognizes this change yet and it still shows 3G of size.

So now I have some questions, hoping you can help us:

Is it that the 6 rows left could have the 3G of information? I wonder if truncating the table -that is deleting all rows- is safe for the drupal installation?

What could we do to update the system information about this file?

Thanks a lot in advance Enrique

Hi Enrique,

Worked with Jamie to repaired table and seems to have done the trick.

Let us know if it's still an issue for you.

Disculpe el retraso Enrique, fue Jamie quien lo hizo.

Jamie can you note what you did to repair this table?

I ran repair table. I think that should do it. Is it not working in this case?

You can also try:

TRUNCATE TABLE cache_form;
REPAIR TABLE cache_form;

Any drupal table that starts with cache_ can be safely truncated.
