Fangtooth BETA Code Freeze, Compression Comparison, Kris talks BSD vs GPL | TrueNAS Tech Talk E012

[@chrisparkin4989]

Wow. When you guys said you were going to talk about licensing I thought I’d fall asleep but that was super interesting and the best episode to date. Please can we have more story’s like this? Perhaps some more about iX and their journey and ZFS and how it got here today? Also could you talk about other filesystems such as BTRFS and why in your view it’s not been as successful as ZFS. Thanks guys, love the show.

Good topics, I think we can do something along those lines in a future episode.

Thanks for answering my question from a couple weeks ago about your licensing preferences. Your answer was excellent.

[@T3-Podcast]

You got it! It was overdue :)

I'm running Fangtooth right now. There are a few things that cpuld be improved. DHCP - I'd like all interfaces to be dhcp capable. Even better would be a way to see the Mac address and Virtual Mac address for dhcp reservations. SMB.- you support sub multichannel but seem to block multiple interfaces on the same subnet. Apps and Virtualization - I'd like to assign Apps and Virtualinzation to a specific network interface. Lock the Dashboard to 1 interface and let the Apps (Nginx) set to use another for Proxy and Reverse Proxy. This also let's nginx and non-httos Apps not get hard blocked by modern browsers. Network- I'd like to see specific icons for status (no media/connected). Definitely want an easy way to get Mac addresses for nics, vlan, macblan.

Imma do a fresh install of Fangtooth. My only concern is - will I be able to import my encrypted drives?

[@T3-Podcast]

How are they encrypted? ZFS Native Encryption or GELI? GELI will not import, but ZFS native will.

Does that imply, if you are doing a network transfer into a TrueNAS dataset that has LZ4 (or compression of any kind) on a pool of fast drives, over a higher bandwidth network than the "speed" of the compression algorithm (I'm uncertain how this is an absolute value that is irrespective of CPU horsepower/other system performance specs, as seems to have been implied), that the transfer rate will be bottlenecked at the compression step?

[@T3-Podcast]

Compression speeds are definitely hardware-dependent - the numbers Chris is mentioning in the video and shows on the scatter plot are from a TrueNAS Mini system. These are also "per core" speeds so they will scale up with core count. Suffice it to say, on any reasonably modern system, you're much more likely to encounter a disk or network bottleneck long before you hit a compression/CPU one.
