A

Hello, hello, it's uh Wednesday, January 4th 2023 and it's signal CI meeting welcome. Everybody today is the first meeting after holidays, uh so not many people and not much on agenda I would want to consider it on triage and uh but first I wanted to point this out that after holidays I looked at uh test grid and this cryo, all the characters are suddenly failing. Like totally failings. It's not even starting yeah.

B

uh In the cryo world we have uh we're aware of this and we're working on it. It was a merge that we made before the break so uh should be fixed soon.

C

Yeah we are this morning, Ramesh told me that he was able to run it successfully locally uh and uh we just have to bump the cryo version in test info.

A

Okay, it's good to hear.

C

um He will yeah, he will send a PR in a day or two.

A

Yeah yeah, we have the same and preset needs, for instance. So please admits we also have a couple credit jobs and it's also read.

A

Okay, so yeah I'm glad it's been attacked um so yeah and let's go to the port, not many items there. Even though there were holidays something new appeared here.

A

It's just 12, and it only shows four, oh because I have a GTM filter.

A

Ing images from private registries.

A

Yeah I'm not sure if it's not related yeah common node.

A

I can see how it can be useful.

A

Does anybody wants to take a look.

A

Okay, Patrick is already assigned.

A

Yeah I would say we'll take it.

A

Says Patrick I, don't think we need to have somebody, it's mostly infrastructure, so related to us, but uh not directly.

A

Product storage, test.

A

Yeah, it's mostly storage, I'm, not sure how much uh they need from us.

A

Maybe this one yeah the storage to do stuff.

A

And that's also merch commits.

A

And I recovery for by checking it difficulty device, exist.

A

A

It looks pretty straightforward, do you have anybody who assigned no videos are signed.

A

I'll go ahead and ask questions to review first.

A

A

Stitching here.

A

A

Yeah go ahead um open.

C

A

A

Oh nice position to CCM, but.

D

A

It's uh it's original author, okay,.

A

A few more foreign.

A

A

We should get related codes.

A

A

Yeah, it seems outside of scope of this one. It's mostly called changes.

A

Yeah, it's also not related to us for Windows.

A

We often assign it to uh Daniela, but.

A

Okay, it's already have plenty of people reviewing it foreign from our team as well.

A

Is anybody interested to take a look.

A

B

I could try but I. You know, I, don't really uh know much about Windows, but I could do a cursory review.

A

C

A

Now, let me ask around: maybe I can find somebody who who knows Windows who can help everybody. You will spend time on uh some other people, maybe use it okay with you, but you still want to think yeah yeah, that's fine, okay, I will I will ask it out.

A

Let's just use printf so uh forever, config too yeah same it's. uh Some big change across multiple seeks. Don't need to take a look sick testing, typically I, look into those foreign.

A

Yeah I also yeah. There were some questions about some LG TMT PRS, but uh it's for Francesca. We want Francesco to take a look, so I will uh GM if his background location or holidays.

A

Is there anything else that people want to talk about related to test.

A

Excuse me yeah: if nothing about test uh I think we can go to um bhaktiash I want to finish with all the triage and then we can discuss. Maybe some active tasks that you have black triage for battery to go here.

A

A

Every time after holidays or occasions, it's uh growing very big.

A

A

A

A

And this one and one CPU.

A

A

Scope means that entire Port needs to be scheduled in a single normal node.

A

You can see messages, documentation.

A

On the call aware of that, foreign.

A

Yeah, it's clearly stating that uh entire Port needs to be scheduled, I think it's missing the saying of how it works.

A

A

Two point: restoration, Trading.

A

Apology manager again, my CPU manager.

A

Oh, no, it's a checkpoint.

A

Yeah I I, don't know this logic very well.

B

Now you can assign me to look at this. I might assign Adrian who worked on the checkpoint, restore, but I can do an initial triage. Okay, okay,.

A

A

It's just that Adrian asking for more details.

A

Do you want me to put in this information or you'll? Do it.

B

uh I yeah sure you can add needs information. It looks like it actually looks like Adrian's already pretty much done. The triage part and they're just trying to figure out the two of them.

A

They're at so yeah I wonder what information we want to ask specifically version.

A

The picture wrong Okay so.

A

I I wouldn't assign to you, then just keep it in this information.

B

Yeah, it is easy see me, though, okay or just tag me.

A

Controller manager.

A

A

It seems to be very simple fix.

A

Just accepted already.

A

Does anybody wants to take a look and change the look statement.

A

A

Oh, what if that has got this plot pointer? Oh my.

A

A

E

Takers, you can assign it to me I.

A

Shall thank you.

A

I'm sorry I forgot. You uh h, h e r.

D

C, h e: it's a chair.

A

A

Let's use that forward, but uh yeah, if you can help with that great.

A

For the time to resign project, ID.

A

What is Project ID.

B

It might be for quotas yeah well uh for, like uh storage with Emerald storage quota. uh What run time are they using.

F

B

uh Yeah, but uh if you continue to be a cryo.

A

Our key, what is our key.

B

um We're guessing Rancher compute uh kubernetes engine, so it must be continuity.

B

Oh yeah by the continuity was.

B

It might be something well um yeah.

F

I guess it does.

B

Kind of look like cute, but.

F

Yeah, it's an alpha feature guide for kilowatt, um it's all mer and all of my list to look into deprecating or keeping this feature gate around.

F

um You can assign it to me or Phillips.

A

A

And uh can be reproduced for the screen removed, okay, so yeah. It seems that it have plenty details: okay,.

A

Somebody wants to promote it to Beta.

F

I think there's too many bugs to promote it to Beta, but it's uh the evaluation that we need to do.

A

You guys scientists to you as well: okay,.

F

Yeah, that's fine.

B

I think I, remember, hearing also that uh there was a like bug in projects in general, where, like a user inside of container, could change the project that they have, so it doesn't even actually work to do secure like isolation for security, for like from a particularity standpoint, so I suspect we may actually be looking at deprecating it instead.

A

Okay, yeah I agree.

A

Okay, I, don't like this kind of title so about to Prevail in which Edition status some date.

A

Okay, seek networking.

A

What happened here, thank you.

A

A

In this one, what version.

A

A

Okay, maybe also very old.

A

Yeah this sounds familiar.

F

Which version? Are they running foreign.

B

Looks like it's a storage.

F

Thank you yeah, and they just refactored some of the PV mounting stuff I. Think.

E

Does it only happen in case of NFS no.

D

First line says: it's specifically said: NFS.

A

Yeah, it's just an effect, but it doesn't say big threat. Anything else.

E

D

Even in summary, they explicitly mentioned that, like mounted on an fspv.

E

Now, because if they are not shutting down, clearly, the NFS might have stale mounts and whatnot.

E

D

Looks like a storage to me.

A

Yeah I I, don't really know this code very well. To tell whether this description description sounds logical. If you just read it but uh I I, don't look at this chord.

A

A

A

A

We need to have a tool that will visualize all the normal assignments and in different situations.

A

Two circuits each shot: it's two normal nodes, yeah. They have big machines for sure.

A

Pure adjacent Bolt.

D

D

A

Okay, so Francesco accepted this.

A

A

A

Yeah by Francesca, so I hope it just about I hope. It's a bug. Let's see.

A

Thomas Edwards get finished after two minutes.

A

A

B

B

It just looks like this has a memory limit and it was being memory throttled.

B

B

A

A

For this area to see, does anybody know.

B

B

Command line, download utility.

A

A

Sweetie uh but a cute chick name for download.ct.

A

I think Coral was also critic name, if you don't know important, but there are not yet foreign.

A

Like the second problem,.

B

A

Today, we're looking at.

A

A

A

A

Yeah, it may be double it, so, let's remove signaled.

A

A

I was keeping created.

A

So Graceful note shut down supposed to put some things.

A

A

A

Okay, so what do you expect to happen?.

A

Yeah, it's not ignored.

A

uh Although we can, we may have some specific date for graceful termination.

A

I know that uh in Red Hat you use a lot of long terminating like nodes. Is there? Is this probably my record? Is there something you want to look at?

A

The problem is that uh when node is gracefully being terminated, uh some Demon said that uh schedule like the tolerate everything, uh because they want to schedule uh ports very early in the not life cycle, so not just bootstrapping, and they immediately want something on this note, so they tolerate everything they want to make sure that, uh even though they tolerate bootstrap phase, they don't tolerate I mean they don't been scheduled on graceful shutdown stage.

A

They need this kind of separation.

A

So that they will come up.

F

Oh yes, I think Joel and my team can probably look at this since it's graceful shutdown, so I'll volunteer um and he's not here. Okay, yeah, this handle.

A

F

J-O-E-L Smith s m okay, yep.

A

D

D

A

With memory leaks for asking questions advisor.

A

Is it generator.

A

Okay sounds components: version yeah, one engine.

A

A

Box today, but I'm not sure about it, but which Fields available as files.

A

A

A

Website, okay,.

A

A

For so long all right, we already looked at it before.

F

Yeah I can continue to look at this one.

A

In the link excuse.

D

A

You need a link. I can send it in the chat yeah. Please.

A

Yeah you mentioned that it may already be done so uh yeah we'll be good.

A

For the successful mode, but.

A

Very old supposed to.

B

A

A

Well, I remember that I wanted to look deeper, but I never did so. Yeah I will keep it for myself this year, we'll start with config Max volumes.

A

Repair versions: basic Romance.

A

D

A

Yeah this video apply sticknote here, foreign.

A

A

Foreign 119 Plus I'm, pretty sure we don't output that.

A

I want to take a look at this uh piece of code and add API version.

F

Yeah I can you can assign it to me.

A

A

A

Specific uh placing code so probably easy to find.

A

Also, very old also.

A

Yeah I still think 600 may take a look first.

A

Yeah, let them take a look.

A

A

I'll give him another week restart.

B

A

Well, I remember that I wanted to check the documentation.

C

Sorry was it: what is this issue about.

A

So this issue was about Google being restarted and then uh containers are shown as not ready uh during this restart and I. Think we have this reported many times already. Could.

E

You could you see me I'm, also saying something similar somewhere else.

C

Is it? Is this fixed like no.

A

I think uh there was an idea to fix it by checking API server for last status of the spot. I mean Google's been restarted, so it doesn't store a Readiness state in any place and since it doesn't store it when it starts, it assumes that pod is not ready.

A

um So if Kubota restarts- and you have like many ports, all the ports will go to not ready first and then to ready back to ready. So it caused a lot of problems with like let's say you have endpoints configured for all the sports, and this endpoint collection will be updated once and then updated another time when they get to ready State again um so yeah.

A

Let's uh I mean it's not very good behavior it just uh all we can Implement and uh we don't have really good idea how to store a Radiance status between restarts. um That's why it's still here.

C

Okay; okay, thanks for that, I am seeing something similar reported.

E

Internally, so I'm just want to see if these two things are similar yeah.

A

Yeah, if you can comment on the back of it yeah, then last one okay, Friday.

A

A

So Lana recently reopened it because of what thank you. Okay, it's going to clean up.

A

A

Okay- and we done with the Box.

A

A

I'm actually very happy that we cleaned up all the three art box. It means that we we can start with more agenda items for next time. Anything else uh from today. Any I think you want to talk about. If not, then thank you. Thank you for attention and uh happy New Year again, bye.
