Revisiting ZFS and FreeNAS in 2019

@xrobau said in Revisiting ZFS and FreeNAS in 2019:
This is where the zraid stuff scales. You can have a ZRAID8 for example (requiring 9 or more disks), where there are 8 copies of the data. Literal copies. The data is replicated onto those disks. There are no parity calculations, as there are with RAID5 and 6.
So, as long as you can get the idea of parity out of your mind, suddenly the zraid stuff makes sense.This is where it was really off of the rails. All of the details in this explanation of a system that doesn't exist. Tons of "and because of this... this other weird stuff". Raving about this "literal copies" stuff, and some eight way system, the new ZRAID name, something that requires nine disks... so many false features. This wasn't casually getting mirroring and parity backwards, an entire new product world was built in his head around this fantasy he had concocted. There must be six made up things just in this one statement that all are required for the other to exist.
- ZRAID (made up term)
- ZRAID8 (ignore the ZRAID bit, there is no RAID with the number 8 in it.)
- 8 copies of data. No RAID level does this except RAID 1, and that's just a mirror.
- 9 drives requires. Why nine? Who knows, but no RAID level has ever required that.
- Copies (the wrong term for mirror but whatever) instead of parity.
- Special scaling based on this made up technology.
Six discrete fantasy products, features, or requirements in one statement. There is, in fact, not a single factual thing in this description, not even buried in the subtext.

ZFS works on copies. So, when you write 1, 2, 3 and 4 to a zpool, you get something like this:
Disk 1: x 1 x 3 x
Disk 2: 1 x 2 x 3
Disk 3: x 1 2 x 4
Disk 4: 4 x 2 x 3
Disk 5: x x x x 4
Copies. Of. The. Data.And this, so much detail about made up products. Where did this all come from? It's like a whole novel about a fake storage technology had been written somewhere.
You know, I once was in a college class and one of the kids didn't know the difference between fiction and non-fiction and in a serious article on ethics they used the "Laws of Robots" from iRobot. This is like that, somewhere there must be some source for so much details, but what it refers to, we will never know.

As a bit of a rebuttal, you're kinda getting confused and claming FreeNAS is a bunch of things it isn't. In fact, in that 'common myths' page is ... I dunno, random made up stuff?
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
So, as a Solaris administrator from way back, let's go through a couple of the misapprehensions about ZFS in that document you linked!
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
I am your guest ZFS expert! Ask me anything
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
Truly, honestly, that's not how ZFS works. I cross my heart.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
Dude, I've been doing this for almost 30 years
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
I got my Windows cert, and CCIE, and a bunch of other things before moving into DevOps. So, please - trust me when I say I know what I'm talking about.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
Honestly, this is where you are 100% wrong, and you refuse to listen to me.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
But telling me I'm wrong isn't going to get you anywhere, because I know what I'm talking about here. This is my field of expertise.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
Now, if you can take a breath, admit that you've learned something new about ZFS
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
I've been using ZFS for 15 years now, and I'm extremely confident in my knowledge.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
I'm a sysadmin. I've done courses.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
I now have to quote multiple things, scroll backwards and forwards, and generally waste even more of my time.
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
This is what frustrates me here - I know this stuff IN DEPTH
@xrobau said in Revisiting ZFS and FreeNAS in 2019:
you're trying to claim that you know this better than me, when you obviously don't. It's massively frustrating.
This is the greatest collection of "I'm smart and I'm an expert" statements I've ever seen. The more someone has to tell you how brilliant they are....

What's really funny is that after re-reading this thread, the most likely thing is that he's never used ZFS and doesn't even know what he has. There is no way he's been actually using ZFS for fifteen years. First, because there is no way someone has ever used it at all and knows so little about it. But second, because ZFS has existed for fifteen years

Right, but claiming to be an expert and putting this as a basis of being an expert is laughable.

Lacking basic knowledge is not bad. Lacking the most basic knowledge while repeatedly berating other people and claiming to be a domain expert so cover up a long series of lies is the issue.

Yeah that is the part that is a problem.

Did you actually read the entire thing? Anytime Scott goes on those 8 post rants where he's writing a paragraph to every 4 words, I have to just skip those. Kudos to anyone who survived the whole thing.

It's tough, because the "four words" is making a false claim, and then I have to provide real IT and documentation to refute it. So not a good way to make it less wordy, because I have to explain concepts behind things in each response.

It's taken some time to get used to, but I feel like it's easier to read because he's addressing each point separately. Wall of text is for sure harder to keep on point when really breaking something down. How he strings 6 replies in a minute is still a mystery to me though.

I read the entire thing. If I Cherry pick I may miss a detail that would be helpful for me to learn.

Wow! Brutal honesty

If you look really really closely at the subtext there is a

He very well could be, thus the fervent shouting about the myths of FreeNAS and ZFS. You have to question someone when they are so impassioned about a topic, but can provide no proof.
