db1246 fully repooled.

Cloning from db1182 completed successfully.

[+Kwaku]

Stalling until db1164 is back in service: T307198: db1164 fails to POST/boot/etc

I've set the host to 'failed' in netbox: https://netbox.wikimedia.org/dcim/devices/2999/

On the web console, i can see it get as far as this before resetting:

Success.

As @Zabe says, T233004 is stalled on this. Is there anything I can help with? This might be more of a "teach Dan how to do this" slowdown than a help, but gets you an extra person to help with these kinds of changes in the future? Anyway, I'm game.

The script dropped the connection after 2h15m.

As an example, i depooled a host (db1120) so i could reboot it. 1.5h later, i'm still waiting for refreshLinkRecommendations to drop it's connection so that i can actually do the reboot. I have no way of knowing when that will happen. I also don't know how bad/disruptive/etc it would be to just reboot it anyway.

For what is worth, es2029 and es2030 are scheduled to be done 14th, which is a bank holiday for me, so someone else would need to bring mysql up once that is done.

Note for next time: various references to the username also needed to be updated. E.g.:

The only thing left is to check (by DBAs) that the backup available at (e.g.) : dbprov1002:/srv/backups/dumps/latest/dump.db_inventory.2022-04-05--03-13-31 looks as expected (content-wise).

One last thing- does orchestrator + zarcillo server have a name? Backups (jobs) have a completely arbitrary identifier for monitoring purposes- any suggestion (even if it is orchestrator OR zarcillo containing both)? Alternatively, it is possible to setup separate backup jobs, even for the same server.

@Kormat I can help setting up backups, but someone has to make clear first what to backup (what databases?), from which servers/dcs, and how frequently they are needed.

@jcrespo: Can i hand this task over to you? I think the dumps grants probably need some cleanup, if you can have a look at that, too.

Regarding the plan I would include the following steps before dropping the database in db2093:

• Check current grants on db2093 to make sure they are the same on db1115

I'm afraid we have to cancel this maintenance for now. Hopefully we'll be able to do in the next couple of weeks, but i'll open a new task for that when i have a firm date. Sorry for the hassle <3

Change 768657 had a related patch set uploaded (by Muehlenhoff; author: Muehlenhoff):

[operations/puppet@production] Remove cumin2001 from mysql root clients and related grants

https://gerrit.wikimedia.org/r/768657

Apart from merging this, we also need to remove the grants from production (@Kormat would you be able to take care of that?)

I'm working on the wmfdb + wmfmariadbpy sides of this for data-persistence. wmfdb is good to go, i'm currently doing some testing with wmfmariadbpy in pontoon in preparation for doing a new release in the next day or so.

Deployment complete.
