http://img505.imageshack.us/my.php?imag ... 276lt0.jpgAfter importing 10 mil hands which lasted for over 3 days, the housekeeping procedure closes to 2 days. Is this normal? Is the cache update the last step? Any tips to speed up the process?
Thanks

I haven't had any data on such a large database, but yes, the cache update will take a long time. When it finishes, would you mind telling us how long it took?

It's at 80 hours and still running. What's weird is that CPU usage doesn't go higher than 30% and averages 10%. Why is it taking so long and doesn't use any CPU? I think I'll give it another day and then shut it down.

Check out this post by Kraada - it should allow you to check whether it's still doing anything.
It's really hard to say how long it will take - as I said, I haven't had experience with such large databases.

after 87 hours, I got the message Housekeeping canceled: There were errors during the housekeeping process:
Unable to execute query: CREATE TABLE "new_holdem_hand_player_detail" AS SELECT * FROM "holdem_hand_player_detail" ORDER BY id_player DESC, id_hand DESC;; Reason: Fatal Error (ERROR: could not extend relation 1663/17632/40967: No space left on device HINT: Check free disk space. )
While i still have 21.6 GB left. Any clues?

Postgres uses a lot of space to do these operations - pretty much the size of the database as I understand it. When the operation ends the space will be freed up, so presumably that's what's happened here - the space will be released even if the operation fails.
