I've only been able to achieve 500mbps over the network when using ZFS replication to another box. I've tested this for months on various machines in various locations on the network but normally get 400mbps at best 500mbps. Has anyone ever achieved better and if so did you do anything clever to achieve this?

Thanks

Yet another TinTin thread.

You realize you've make more than 1 thread a week on this forum. I'm not even kidding. You've made 24 threads on this forum since you joined in February.

 

[TinTIn]

Sorry

Not to sound rude, but if you were sorry you wouldn't keep making more threads... you'd find a contractor or otherwise to do this for you.

The fact you've had to open 24 threads is just a sign that you are woefully unequipped to deal with FreeNAS on the scale you are working on.

I've told you this more than once, and I don't really know how much evidence you need to get this into your head that you should not be doing what you are doing.

 

[TinTIn]

Sorry cyberjock I have clearly misunderstood the idea of the forum. I will no longer post questions. Again I apologies for causing any offence. All the best.

The point of the forum is not to be your personal one-on-one coach for server issues. That's what it feels like when you look at the number of threads you've created.

If you have a problem, or a couple of problems, great. But 24 problems in less than 3 months. You need more than just a question or two answered.

Feel free to keep posting, just don't be surprised when everyone figures out you keep on posting questions and they decide to ignore you. You can't expect volunteers to help you manage a server with every little problem that comes up. That's what paid support (or even paying someone to give you the education to become becoming an expert yourself) is all about.

I'm not sure we are both interpreting the concept of sharing knowledge the same way. I don't pick and choose when to share and when to keep it to myself. If I know the answer or have an opinion I'll give it. I've been working in the IT industry for the last 14 years and provide advice to people worldwide on a variety of platforms however my knowledge of BSD, FreeNAS and storage management is weak as its not something I've needed to be involved in. If someone asks me a question I don't pick and choose if they are worthy of the answer as one day they may be answering one of mine. I'm sorry you feel this way however I do not believe that the rest of the forum agrees with you. Anyway I'm sure there must be another forum you can go on and be a grumpy bugger.

Few things:

1. I was asked by two different people to say something to you, forum users with less than 500 posts. People don't like the feeling of donating their time to a company that should be paying for support or for training on a subject,, especially a server with a cost as high as yours is. So I am most certainly not the only one. I was content to simply ignore you.

2. I have zero idea where you are getting the idea that I thought you pick and choose what to share and when to share. You totally lost me on this. And to be frank, I really don't care what you were trying to say.

Everyone here is a volunteer. Nobody here is paid to post. Nobody.

I've been sharing knowledge here for more than 4 years. So far you've done nothing but opened a bunch of new threads (2 a week on average, many on topics others feel have been discussed thoroughly). So when you want to mention sharing knowledge.. I don't see you doing much of that, but asking a whole lot of questions that you should understand before building a server of the magnitude you have.

Yes, I am going to be ignoring you again, but if I get more comments from people asking me to say something to you, then we'll take it in PMs with appropriate action.

You'd be wise to check your presumptions about who feels what in this forum. You'd also be wise to not ask a bunch of questions that might put you on people's ignore lists (which is why I tried to hint at it just a few days ago when I said what I said). If the top 10 posters decide to add you to their ignore list, you'll find that virtually nobody here is going to help you. Someday you'll figure out I said what I said on Sunday because I was hoping you'd get my clue and not open another thread. But here we are with another thread on Wednesday.

I guess you don't get many people on the forum attempting to mange storage on this scale hence why you are being so negative towards me. However Im surprised your not embracing the idea that this fantastic ZFS filesystem/volume manager coupled with this fantastic FREE open source storage appliance OS can be used in enterprise and on this scale. Having your default view of its big so you gotta pay is what gives rise to the Nexentas of this world. When OpenZFS went live Im sure it wasn't really part of the plan for large compaines to slap on an OS and then charge a fortune just for the privilege. You're right I know very little about this topic and I don't pretend otherwise but I equally am not ashamed to ask questions. I guess we've all gotta start somewhere and as I've said before I wish I was starting on a small scale and I also wish I had the luxury or partnering with a large company on this but I don't and neither of those decisions were made by me. If my threads are upsetting people then Im sorry all and please feel free to ignore me. I think some of my threads have actually been quite useful and not just for me. The GZIP9 issue appears to be a bug although your fix is to not use it which as a very IT way of doing things. We all start young with little to no knowledge and we ask questions, we build, we make mistakes, we learn from those mistakes and then we find ourselves answering the questions. Thats called the circle of life cyberjock and perhaps your nearing the end of that cycle.

I don't always agree with cyberjock, but I concur with what's been said.

I don't have anyone on an ignore list, but In general I haven't commented on your threads.

Some of your early questions were along the lines of improving performance before you'd even bought the hardware. I wouldn't have asked that question unless I had the hardware and had done some benchmarking with it beforehand.

I've got 30+ years in IT and I do a lot of homework to expand my skills.

Given that you are being paid for this server work, you need to figure out most of these answers yourself.

The early questions were based on test servers I'd built. Always good to test before you put a production server into an enterprise environment. Like I said if I've upset anyone then I'm sorry but I don't look at things the same way. The thought that I'm trying to get people to do my job is a joke. I wish all I had to do was ask some questions and bang all is well in the world. Clearly this has been taken the wrong way so I'll end the posts. Good luck to you all.

The problem with your questions is that you phrase them like, "It's broken someone help". It doesn't appear that you put any effort into learning anything and after about 3 of these threads people start to take notice and don't want to help. This is a community forum so it is just as important to ask questions as it is to learn about things and provide answer to questions or solve them yourself. If you truly have worked in IT for 14 years you should be able to provide more content and insightful information then most people on this form. I have 0 years of IT experience and usually provide more answer then I do questions here and I just use common sense. If I have a question I go figure them out and don't expect someone to just tell me the answer, and if along the way of me figuring it out I have a question about something I first search for it and read. If I don't find what I need I ask a question that is specific to my problem and usually has a very specific answer. Most of the threads on this forum are of people asking questions that are so broad that they can't really be answer and it takes 10+ posts just to figure out what the OP actually is asking a question about.

For example this thread you asked if someone has seen better than 500mb/s with replication the answer is yes they have but maybe they had 4 cpu's 256GB of RAM and 40 GigE. Now you need to figure out why you can't see those values. Go learn about about benchmarking, how a computer and network actually work. Then you will be able to answer the basic questions and then when you have a specific one you will get better answers on the forums. There are so many variables with your problem. Example: can you get faster speeds using iperf? can you get faster speeds using nfs or cifs? What are your speeds for local reads/writes on the box? are you having caching issues? can your switches handle the traffic? can the other box handle the traffic and caching? <= go learn how to do these things then ask a question theorizing one of them being the problem and why then people can help you eliminate the problem or prove that it is the problem.

I'd like to add my opinion to the pool of knowledge (ZFS pun not intended).

First of all, regarding the Ignore List - mine is reserved for the most egregious of assholes, which is not the case, by far, for anyone who's posted on this thread. In the current context, if I say "ignore", I mean going "meh, I'll check back if there's something new here".

I'd say that's the case here, mostly. The information on the forum is mostly directed towards smaller systems, so it is definitely interesting to see what happens in extra-large systems.

The lack of information on this kind of system means that, when the questions pop up, it's hard to get answers, which tends to lead to questions being asked. This is only natural and also applies to similar situations, like Tyan motherboards, for instance.

With that out of the way, a few specific comments on the current situation:

• As said, professional support is definitely advised. I'm not arguing against that.
• I agree with SweetAndLow's assessment that more information in the thread starter would be useful in a "difficult" question
• I don't think it's inappropriate to ask real questions with answers that can't be easily found (due to lack of information, need for interpretation or whatever reasonable difficulty)
• I do think it's inappropriate to believe that every question has a universal right to receive a proper answer (I'm not saying it's the case, just a general observation)
• I do think it's inappropriate to complain about someone asking questions. If you have an objection, please feel free to refrain from participating in the discussion. Much like the code itself, having companies benefit from a free public discussion is not something inherently bad and spinning it as "you must pay for systems greater than X because my philosophy keeps me from helping you as a business" is incoherent and a disservice to the community, as knowledge of large systems stays contained within a relatively small group.
• I can understand people not feeling like answering yet another question, but I'd argue that this case brings more to the community than the average "No, you can't just add a single disk to your pool" or "No, you need 8GB of RAM, minimum" kind of scenarios. In other words, the discussion itself does not seem objectionable.
• Finally, the potential for this to end catastrophically exists and is a valid reason not to participate.

Heh. Honestly there is one tintin thread in the last 600 'recent threads'. That is hardly an objectionable amount considering some of the winners that come through here. Dude has always been polite and appreciative of help.

That said even the decent hardware isn't enough to hold my interest on these. Sweetnlow likely has the issue well described.

@TinTIn, I'd say keep your quick questions in a build thread or something. Lots of folks will contribute to an active interesting project. Though admittedly I'm quicker to help johnny who is in over his head and making bad choices than someone getting paid to know this.

Perhaps I'm too easy going, but I haven't found your frequency of threads annoying. Inane perhaps... But not annoying. ;)

Hear hear!

I do have the sinking feeling that tin tin is in over his head and this at not end well.

 

[Darren Myers]

did he edit all his posts with * ? @cyberjock

 

[cyberjock]

Yep.. he's being immature.. can't say I'm too surprised. I'll fix this... :)

 

[cyberjock]

Fixed. :)

I'm happy I don't have him working for me. That's the kind of guy that sabotages your crap on his way out.

Real standup guy.. ;)
