For the record: the alter on labsdb1001 has been killed because we ran out of space there, same thing will happen on labsdb1003, so we need to find a solution for those two hosts before applying this change.
If we start using this column before it is applied there, it will break replication on labs.

We have hotfixed the issue by removing an unused partition and adding it to the main volume. So l am re-running the ALTER on labsdb1001 now.

Hey @Marostegui, I can't see db2023 (master in codfw) gets deplooed and repooled (maybe you don't do that for masters). But I don't know if this schema change is done for db2023 or not. Please tell me once it's done, so we deploy the config change.

jcrespo added a comment.May 9 2017, 4:17 PM

Please @aude @Ladsgroup don't stress Marostegui! :-) As you can see he is currently working (very hard, I would say) on this, but you need to be patient. Schema changes take time, and they require careful checking after the fact. Marostegui or me will resolve this ticket or move it to the "Done" column when we are confident it is finished. Until then, even if you see it mostly completed, any deployment assuming this is done would risk a site-wide outage due to replication getting broken, and you probably do not want that!

You will be the first ones to know when this is ok to proceed.

Ladsgroup added a comment.May 9 2017, 4:21 PM

My apologies. I was a little bit confused about the codfw master. Thanks for letting me know.

We do not pool/depool masters. That is why you don't see the change. The master is currently being altered. It will take a bit longer than the rest of hosts as the hardware is less powerful.

As Jaime said, you will clearly know when the whole shard is done. We will say so on the ticket and close it. Please be patient :-)

i checked test wikidata (testwikidatawiki) and it needs the change also. the tables there tend to be small.

select count(*) from wb_terms;
+----------+
| count(*) |
+----------+
|   192947 |
+----------+

Is it safe to apply this schema change test wikidata on terbium? (like how we add new tables) me or someone else can do that, if it is ok.

Hi!

I can do that, however I am a bit confused, is it terbium what you really mean?

@Marostegui for small schema changes (e.g. adding a table, or for small wikis like test wikidata), we normally apply schema changes run it via mediawiki maintenance script:

https://www.mediawiki.org/wiki/Manual:Sql.php

We should just be sure it's okay to do this one this way

Sure, that is fine by me if you want to do it yourself, but on which host does that test wikidata database lives?

jcrespo added a comment.May 14 2017, 11:50 AM

@aude: don't run update.php on s3 for altering a table- you will create lag
on 900 wikis unless connections are cleared and table is pre-warmed-up (and
appropiately tested).

Also, the only wiki mentioned here was wikidatawiki, you have to create a
separate request for other wikis.

Ah, thanks for the good catch, I didn't know he meant s3 (I thought he was talking about another small host or something that wasn't on my radar, hence my two questions to see where that database he wanted to alter lives in, as I was planning to check the table size and if there were slaves or stuff).
I am glad you mentioned s3 now I have the full picture.
