OP here. Thanks for the comments and suggestions! I updated the post to include the full text of the email as well as a link to this discussion. I wonder if anyone has any suggestions about what we can do to stop this kind of thing. Should

Great idea! I just updated the post with the entire text (unlinked)!

I'm glad to see so many folks listening/watching! The On-Premise IT Roundtable selects a controversial premise to discuss on each episode, and it appears that this was a good one! If you'd like to join in a future discussion,

Find me these “properly programmed devices”! This is the core of the issue: bad assumptions and poor QA let bugs like this have an outsized impact. It’s our fault, folks.

Thank you! I appreciate both tips!

There kinda isn't such a thing at this point. I sure wish there was! And this is the point behind the article: Wouldn't it be awesome if ZFS had continued developing as the super filesystem it looked like last decade? It would do

I guess I'm an old storage guy. I call it the FAT on everything! :-)

I'm sorry, I was referring to hybrid storage as a technology category, not the hybrid disk drives like Seagate Momentus XT. You're right that a 2-drive hybrid (Fusion Drive) will mathematically be less reliable than a non-hybrid o

I realize that not everyone lives in the world of enterprise storage, so I appreciate your question. ZFS is a filesystem (and also kind of a volume manager) and is designed to be fairly versatile and to run alongside an OS and applications.

I didn't even consider this. Thanks for the explanation! Makes tons of sense! Incidentally, many modern filesystems (including NTFS) store very small files in the FAT rather than taking up a whole block for this very reason!

Yeah, as mentioned in the post, you can indeed just add a vdev to the pool whenever you want. But the risk, apart from performance, is data protection If you add one disk, your whole pool is at risk. So of course you have to add two or more

Hybrid storage combines flash and disk for better performance and lower cost. Most hybrid storage is tiered, meaning that data can "live" on either flash or disk, but there are other approaches that look a lot more like a cache (s

Enterprise Storage == Real Storage Arrays Basically every storage array is years beyond ZFS in terms of features and capabilities. Even the ones based on ZFS! And I don't think anyone would argue that. After all, Dell EMC, HPE, Pure St

Yup. This. Now that I have 32 GB of RAM in my FreeNAS box I decided I really didn't need dedupe after all. I just don't have that much duplicated data, and I've got 60 TB of HDDs in the box. So I use the RAM for VMs instead!

I had never heard of bcachefs. Thanks for the pointer!

It's in there.

...and most of which won't work with a given display. SO you have to figure out which of the dozen or so possibilities works with your monitor and computer and buy the right cable to go between them.

I agree that it's exciting to have a durable/flippable cable that can be used for all sorts of things. The issue is that the nomenclature is unclear, with everyone just saying "USB-C" when that can mean all sorts of thin

No you can damage your devices with C-to-C cables. https://plus.google.com/u/0/+BensonLeung/posts/HakwCMmd346

You could try them with appropriate peripherals and see if they connect at max throughput... But that's going to be very hard since there are pretty much no Thunderbolt 3 peripherals out there.

Well they did change the encoding of USB 3.0 to become USB 3.1 gen 1. But that's about it. And it's backward-compatible so it doesn't matter. Having the higher data rate be "same name gen 2" is beyond dumb.

Plus, as noted by lee_s2, the higher-cost/higher-protocol cables are "active" with chips in them.

"Alternate Mode" means "use these same pins for something other than USB". So Thunderbolt 3 uses the same connector but re-purposes the pins and wires to carry 2 or 4 PCIe 3.0 lanes rather than USB. HDMI similarly repurp

Fantastic explanation. Right on!

"Everything fits but nothing works" - I love that!

The cables are generally backwards-compatible, but most people will buy the cheaper cables. And those won't work.

by sfoskett 10y ago
"Alternate Mode" means "using the same USB Type-C pins for other protocols". That protocol can be HDMI or DisplayPort or Thunderbolt or even analog audio! The USB consortium specifies using HDMI 1.4b and DisplayPort 1.3
