@Marostegui- this is bad, codfw machine was created as tendril2001 T186123, and this was called db1115. This is not a terrible name for it (I would call it a separate name as misc hosts), but it should have the same name on both datacenters.

We can change it now, nothing has been installed yet but, we cannot use db1001 (which would be the equivalent) though. Suggestions?

Sorry, nevermind. We can use tendril1001

Suggestions?

The easy thing would be call it tendril1001 (which I do not 100% like, as this will be a monitoring db database, but dbmonitor already exists, but it points to the web frontend), the more difficult thing would be to call it something else and rename tendril2001 as that something else.

To be honest, I would call it as a normal database name, to avoid making any kind of exception and having dedicated hostnames (that is why I used db1115) as we never know if we might decide to add more databases to it in the future

To be honest, I would call it as a normal database name, to avoid making any kind of exception and having dedicated hostnames

Which would be ok to me, as long as the other is renamed.

Sure, we can do that and call it db2092.
I will rename this back to db1115 then

Note for that one means involving papaul and renaming stuff, from the physical label to racktables, to dns, etc.

Yep, I was writing on the other task at this moment

All db hosts will have a hw RAID except these, it will be confusing.

ok - I am going to stop making patches and renaming tasks until a name is decided because this is getting a bit of a back and forth and it is going to create more confusion.

Why did we call this tendril2001 in codfw, but db1115 in eqiad?

See discussion at T186123 and starting at: T185788#3940445
(basically when I created this ticket I didn't know it was being decided to call it tendril2001 in codfw) but there is that discussion still on-going :-)

Sorry about that, missed that reply in my quick grep, my bad! So yeah, lets just keep naming standardized between sites. I don't have a strong preference on which ends up being used (though I prefer some kind of distinction like tendril, I understand why it may not be preferred.)

Chris, can you hold this task?
There are under going discussions about the hostname, I marked the task as stalled but I should've said it was blocked - sorry about that

@jcrespo what would be your proposals? As I already stated mine (either tendrid1001 and/or normal dbXXXX are fine with me), but they were not too satisfying, I would like to hear yours so we can discuss them, reach and agreement and unblock our DC-Ops :-)

@Marostegui This server only has 2 4TB disks, with no raid card. This will need a software raid. Let me know if you want to reconsider the naming.

^that was my main reason to object to not call it db*, all db* hosts have a hardware raid and are, to some extent, interchangable.

It's not too late to rename it to tendril1001...easy dns change right now

I am seriously tired of having this discussion again. I already stated my preference and the fact that I don't really care about this hostname or any other one we want to choose. I was fine either way.
I believe you said you were neither convinced with db* nor tendril*. But last Monday we agreed on going for this model.

So if you are still not convinced I would suggest you give some proposal and I will be fine with it most likely. Having this blocked in a hostname decision for many days is not very productive.

no, tendril is definitely not ok.

I did not reopen the discussion this, Chris did. And if our decision confuses people, maybe it wasn't that good? dbmon-be could be an alternative. We can later rename dbmonitor as dbmon-fe.

@Cmjohnson, please proceed with db1115 as @jcrespo and myself agreed on that hostname yesterday in our weekly meeting.

@Marostegui Okay, since I cannot do standard DB raid...any suggestions?

Do nothing, we (the recipe) will install the RAID1 in software.
