Those are the finalizer and distress test are merged and then there's et test for secrets that is being reviewed and there's also a test for metrics.

Okay, thank you.

A

Next one is through the capacity tracking. This is uh patrick's. I don't know if patrick is on a call.

A

So he's, probably, I think, last update. He is making some improvements, so maybe the same so I'll just say no update. For now.

A

Volume, uh so sad: did you attend that meeting? Do you want to give an update on this.

D

A

This is the generic uh uh fmr volume.

D

Oh right, yeah so update here is: uh there is going to be uh basically a a new api for this uh and we're trying to align it with the uh existing csi ephemeral volumes. Patrick is going to continue to own the generic ephemeral volumes.

D

We are looking for a new owner for the csi ephemeral volumes to drive that to beta and align that api uh with the generic ephemeral volume, api and yeah. If anyone's interested. Let us know otherwise we'll circle back internally and see if we can find.

A

A

Is there so the api will be changed for? uh I think.

D

Generic ephemeral volumes is mostly staying intact. It's the csi.

A

D

Volumes, that's going to be kind of shifted.

C

Moved to a line yeah.

D

So he moved under that ephemeral tag and renamed.

A

Okay, so just copy the same thing here.

A

A

uh Okay, so next one spreading over a few domains is the same same thing. This is uh still uh depending on the next item. So it's the same thing and then for the next one voting group api. So I will schedule a meeting after thanksgiving.

A

And we have a few items here, see the auto tree move iscsi driver.

A

Do we have any it looks like we don't have any update for a few meetings now uh looks like michelle is not not on the call right. So do you do you know anything about this? Is this still? I should put down no update for this three.

D

uh What are the three items? Sorry.

A

Csi, auto three more iscsi driver fit and finish, and the fiber channel and the flex volume.

Yeah, I think michelle said she was planning to get to the second to uh after code freeze. I don't think she's gotten to that yet and uh the first one is no update.

A

Okay, so just just do the same, I.

D

Think that's fine.

A

A

Okay, so the next one. Oh look, look at this one is dark, move out, cluster fs provisioner, that's done that's good, uh and then we have a two nfs related move out: nfs, provisioner and nfs client provisioner is karen on the call he's maybe at cubecon.

Next one: okay: next one is volume house, so we are still working on the host bus driver, one house implementation, so the pr has been reviewed. Eq test is pending um because it we need to have that implemented in the hostpass driver. First and next one is the generic data populator ben. Do you have an update on this.

F

um There has been very little progress on this, the last two weeks. Unfortunately, I mean I'm still working on it, but I've had some big distractions. Unfortunately, those are getting wrapped up. So look for progress next month. Okay,.

A

Thank you, okay. Next one is cozy. Is anyone from cozy want to give an update on this.

G

Yeah this is trini. uh We are making good progress on the coding site. uh We are able to make good progress on the csi adapter as well as test driver. uh We are waiting for some decision to be made on the protocol structure.

G

We will be discussing that today in our meeting. um We don't want to have protocol specific fields uh and make them opaque, so that will be. uh That needs to be decided for us to continue with the work on the uh central controller and the provisioner. So that's the status right now.

G

E

G

Kept changes yeah.

E

A

Next one is fs group supporting csi.

H

This was yeah, this was merged and it should be on track for 120. Docs have already been merged for kubernetes.

A

Thank you. So I have a few items crossed out. So the next one is the csm aggression. Vsphere uh is a deviant here by any chance yeah. So I actually have an update, so actually the back part finally got approved, so um it's uh so it so it won't be in the upcoming 201 release, because that one is going to be out soon, but it will be released after that.

A

So that's a good progress.

A

uh Next one c is a migration azure file, so this one is going beta.

A

Does anyone know anything about this.

D

I think michelle said that uh andy found a couple of bugs in core that need to be addressed. uh Basically, this is being worked on.

A

A

All right, so this is still on track or.

A

I'm not sure when okay thank.

A

You see the migration gce.

C

uh We have no update here.

A

A

You migration, openstack cinder, looks like we're still looking for owner any update.

B

um I gave last update that I'll try to find an owner and it's still the same. If nobody else steps up, then the like our team, like miyan and christian, will, will own this piece.

A

Okay, thank you.

B

A

Okay, thank you. uh Next one is a system. Migration, saffs and save rbd, so humble is working on this one. Is there any update on this.

A

Sad, have you heard about this one for humble.

D

uh No, I didn't get a chance this week to sync up with humble I'll, get an update for next time.

A

Okay, thank you, so the next one, okay. So those are a few projects that we co-owned with the sig apps. The first one is address issues pv cd uh graded by staple side will not be auto removed.

A

Is the kk on the call.

I

Hi I was away from kubernetes work for a few weeks. Okay, I'm trying to get back.

I

I will make progress in the coming few weeks. There's also work with heymonth, which I had promised early in november, but couldn't get to, but now I'm back working on all of them so should make some progress.

A

Okay, thank you. So it's the same thing for the next one.

I

Yes, yes, okay,.

A

Thank you so the next one is a project we called with a seek node content. Notifier. uh We still need to schedule a meeting uh to sort out some of the api design issues so and next one is uh this: is I just had it the other day, so this is actually signaled um enhancement, size memory, backed volume, so command reviewed it. So you want to give an update on the smart command.

B

F

B

Yeah, it was merged and yeah. I think it's good it it. It's not that big of a change.

A

All right, thank you.

A

And next one is uh copenhagen, udo's months blue to a new repo srini. Do you have an update on this.

G

Yeah, actually, I ran into a bit of a problem there because c advisor uh pr. I I got merged, but uh we had to revert it back because uh the vendor uh software cannot use the staging libraries, so um uh dims reverted my pr on c advisor. So that is the only component that is dependent on mount details from the staging. Okay. uh Eventually um dim said that uh he'll uh he'll work with me after 120 uh go threes to to to make some progress.

G

I I think the idea is that we are going to use moby amount library, as is for c advisor, probably, but I don't know how it pans out. So.

A

A

Okay, thank you.

A

uh Next one is the one that we call with six scheduling prioritization on volume capacity. I think uh um this one is delayed to 1.21, because I think that he didn't get time to finish tests, so this is a laid.

A

Okay, I think that's all we have on the spreadsheet. uh We don't have any more items here. Are there anything else people want to discuss in the.

A

Meeting all right, then, we'll have a short meeting today. Thank you. Everyone bye.

C

Thank you. Take care.
