Thanks, all that churn without much visible progress to a mergeable codebase was really ennoying. I'd recommend if people want to merge lustre they start with a managable subset first, e.g. the fs client code with simple IP-only networking.

Adding or removing the IB networking makes basically no difference to the code size. This would also make the client much less useful, since a large number of sites use Lustre with IB networks.

Would it makes sense to land LNet and LNDs on their own first? Get the networking house in order first before layering on the file system?

It's not the kernel newbies that are your biggest problem. It's your development model, and lack of support from anyone to actually do real cleanups. Every few months, when I get really bored, I do a drive-by pass and have never yet failed to find numerous problems that you all have been totally ignoring. Look at the debugfs patch series I sent out this week. Look at all of the wonderful work that NeilBrown has been doing on core cleanups for your mess. Neither he nor I should be the ones that have to do this stuff, you all should be doing it yourself. You all have had over 5 years to work on cleaning up your crazy shim layers. It's still not done. And based on the recent patch series that was sent to me, I don't even see anyone planning on working on that type of thing. I'm sorry, but I am tired of it. If you want to submit this for the filesystem maintainers to accept, wonderful, please do so. But that will not consist of a patch that just moves the directories. You have to create a real set of patches and send them to linux-fsdevel, just like any other new filesystem does. And I would like to point out the fact that while this whole thing sat in staging, other filesystems and major driver subsystems entered staging, got cleaned up, and moved on out. It can be done. But for some reason you all don't want to do the real work to do it, which is fine, I understand that you need management buy-in to make that happen, and you all need to focus on your users and new features for them. So if you really do want this out of staging, go off and do the real work to do so and then merge it the "real" way. I'm tired of dealing with it in staging as-is and having to every few months start rejecting new feature patches and tell people that "this is the last time I'm going to tell you..." You all were warned many times, this is not my fault, but rather, yours, or your management for not allowing you to prioritize this work. > Lustre has been in use at large sites around the world for 18 years now. > Over 70% of the largest 100 systems in the world use Lustre. It runs at > universities, oil companies, weather bureaus around the world, etc. And yet, I bet none of them run the in-kernel codebase, right? I bet you could get all of this cleaned up and merge properly in 6 months if you really wanted to do so. But it seems that no one really wants to do that work, which is sad. I should not have to be the one to force you all, but it seems like I now have to be. > I know Andrew has long been a supporter of getting code into the kernel > that users are using.

Because those developers took the time and did it right. Please, compare yourself to orangefs. That is the perfect example of how to do everything right. They got their code into staging, cleaned it up, talked to us about what was needed to do to get the remaining bits in proper shape, they assigned dedicated developers to do that work, talked with all of us at different conferences around the world to check up and constantly ensure that they were doing the right thing, and most importantly, they asked for feedback and acted on it. In the end, their codebase is much smaller, works better, is in the "real" part of the kernel, and available to every Linux user out there. So yes, you are no orangefs, but you really should aspire to be just like them, as they know how to do all of this correctly. > It's true the code is not as pretty as it could be, but the same is true > of code that has been in the kernel for ages. If you know of major subsystems that look at bad as lustre does with the numerous wrapper layers and other crazy things that you all do, please let me know and I will be glad to go point people at that code to help get it fixed up. Also note that the attempt to defend your behavior with "but he's doing the same thing over there!" is not a valid defense at all. I'll gladly go over and deal with your misbehaving sibling after dealing with you :) > We've spent years cleaning it up in staging, and it has gotten a lot > better. Better yes. Correct and mergable out of staging, no. You all have had plenty of time to get your act together. Maybe this is what you all really need to kick it into gear to do it correctly. I certainly hope so, because I think we all can agree that what we have been doing for the past 5 years is NOT working at all. sorry, greg k-h

I'd like to turn that question on it's head: Do we need LNet and LNDs? What value do they provide? (this is a genuine question, not being sarcastic). It is a while since I tried to understand LNet, and then it was a fairly superficial look, but I think it is an abstraction layer that provides packet-based send/receive with some numa-awareness and routing functionality. It sits over sockets (TCP) and IB and provides a uniform interface. That is almost a description of the xprt layer in sunrpc. sunrpc doesn't have routing, but it does have some numa awareness (for the server side at least) and it definitely provides packet-based send/receive over various transports - tcp, udp, local (unix domain), and IB. So: can we use sunrpc/xprt in place of LNet? How much would we need to enhance sunrpc/xprt for this to work? What hooks would be needed to implement the routing as a separate layer. If LNet is, in some way, much better than sunrpc, then can we share that superior functionality with our NFS friends by adding it to sunrpc? Maybe the answer to this is "no", but I think LNet would be hard to sell without a clear statement of why that was the answer. One reason that I would like to see lustre stay in drivers/staging (so I do not support Greg's patch) is that this sort of transition of Lustre to using an improved sunrpc/xprt would be much easier if both were in the same tree. Certainly it would be easier for a larger community to be participating in the work. Thanks, NeilBrown

I find it incredible that anyone would think that not having to "worry about providing valid changelogs" and not "breaking their patches up into logic pieces" could ever be seen as a good idea. I hope that if lustre development is excluded from mainline for a time, that we can still maintain the practices that demonstrably work so well. For the record: I'm not in favor of ejecting this code from mainline. I think that the long term result may be that it never comes back, and will like at least delay the process. But you must do what you think is best. Thanks, NeilBrown

It sits over sockets (TCP) and IB and > provides a uniform interface. LNet is originally based on a high-performance networking stack called Portals (v3, http://www.cs.sandia.gov/Portals/), with additions for LNet routing to allow cross-network bridging. A critical part of LNet is that it is for RDMA and not packet-based messages. Everything in Lustre is structured around RDMA. Of course, RDMA is not possible with TCP so it just does send/receive under the covers, though it can do zero copy data sends (and at one time zero-copy receives, but those changes were rejected by the kernel maintainers). It definitely does RDMA with IB, RoCE, OPA in the kernel, and other RDMA network types not in the kernel (e.g. Cray Gemini/Aries, Atos/Bull BXI, and previously older network types no longer supported). Even with TCP it has some improvements for performance, such as using separate sockets for send and receive of large messages, as well as a socket for small messages that has Nagle disabled so that it does not delay those packets for aggregation. In addition to the RDMA support, there is also multi-rail support in the out-of-tree version that we haven't been allowed to land, which can aggregate network bandwidth. While there exists channel bonding for TCP connections, that does not exist for IB or other RDMA networks. > That is almost a description of the xprt layer in sunrpc. sunrpc > doesn't have routing, but it does have some numa awareness (for the > server side at least) and it definitely provides packet-based > send/receive over various transports - tcp, udp, local (unix domain), > and IB. > So: can we use sunrpc/xprt in place of LNet?

There was some discussion at NetApp about adding a Lustre/LNet transport for pNFS, but I don't think it ever got beyond the proposal stage: https://tools.ietf.org/html/draft-faibish-nfsv4-pnfs-lustre-layout-07 > Maybe the answer to this is "no", but I think LNet would be hard to sell > without a clear statement of why that was the answer. There are other users outside of the kernel tree that use LNet in addition to just Lustre. The Cray "DVS" I/O forwarding service[*] uses LNet, and another experimental filesystem named Zest[+] also used LNet.

I don't think the proposal to encapsulate all of the Lustre protocol into pNFS made a lot of sense, since this would have only really been available on Linux, at which point it would be better to use the native Lustre client rather than funnel everything through pNFS. However, _just_ using the LNet transport for (p)NFS might make sense. LNet is largely independent from Lustre (it used to be a separate source tree) and is very efficient over the network.

That sounds like something that could benefit NFS... pNFS already partially does this by virtue of the fact that data often goes to a different server than control, so a different socket is needed. I wonder if it could benefit from more explicit separate of message sizes. Thanks a lot for this background info!

So RDMA API now is possible with TCP networks. Well, strictly speaking RoCE still isn't possible with TCP networks. RoCE v1 is an Ethernet layer protocol (not IP based), while RoCE v2 is UDP/IP based. Cheers, Andreas

Which might be one reason why it got merged so quickly - allowing rapid iteration without respect to merged windows, and doing all the trivial cleanups either before or after (but not at the same time as) the feature work really does help productivity.

Ah, my mistake, for some reason I thought it did, I guess I had offered to take it that way if the developers wanted it. And yes, doing all of the needed cleanups and other changes outside of the kernel tree should be much much faster, which is why I bet it would only take 6 months max to get lustre merged "properly" if they really wanted to do it, by working out-of-tree. Heck, they already have an out-of-tree repo today, so it's not like removing the in-kernel version is going to change their normal development workflow :( greg k-h

The Lustre filesystem has been in the kernel tree for over 5 years now. While it has been an endless source of enjoyment for new kernel developers learning how to do basic codingstyle cleanups, as well as an semi-entertaining source of bewilderment from the vfs developers any time they have looked into the codebase to try to figure out how to port their latest api changes to this filesystem, it has not really moved forward into the "this is in shape to get out of staging" despite many half-completed attempts. And getting code out of staging is the main goal of that portion of the kernel tree. Code should not stagnate and it feels like having this code in staging is only causing the development cycle of the filesystem to take longer than it should. There is a whole separate out-of-tree copy of this codebase where the developers work on it, and then random changes are thrown over the wall at staging at some later point in time. This dual-tree development model has never worked, and the state of this codebase is proof of that. So, let's just delete the whole mess. Now the lustre developers can go off and work in their out-of-tree codebase and not have to worry about providing valid changelog entries and breaking their patches up into logical pieces. They can take the time they have spend doing those types of housekeeping chores and get the codebase into a much better shape, and it can be submitted for inclusion into the real part of the kernel tree when ready.
