Sure, I can help. That powerpoint is horribly out of date and I'd argue full of FUD (intentional or not). >• Raid 0, 1, 5, and 6 are also built in the filesystem BTRFS RAID has been a nightmare from day 1 including complete data loss. Parity-based RAID has been "just around the corner" for almost a DECADE. Sure you can do RAID-1 but in 2020 I'm just not interested in losing half of my capacity. Yes you can layer it on top of MDRAID but that eliminates half the elegance of what ZFS brought to the table. >ZFS is fairly memory hungry, it's recommended to have 16GB of RAM and give 8GB or more to ZFS (it wasn't designed to use the linux memory filesystem, so it uses its own memory that can't be shared with the rest of linux). This is just flat wrong. You need 2GB of memory for a happy filesystem, 8GB+ is if you're doing deduplication which is unnecessary overhead in most environments. I'm also not sure where the "memory that can't be shared with the rest of linux" is coming from - ARC will use and free memory as needed by the system. >Due to the CDDL being incompatible with GPLv2, a linux vendor or hardware vendor will never be able to ship a linux distribution or hardware device using ZFS Except Ubuntu already is. I believe SLES does as well. >As a result, you shouldn't plan on using ZFS for any product that you might ever want to ship one day. Delphix ships a product today based on ZFS. 0 issues. >Oracle may have stopped further work on ZFS as a result. Or it could be another reason entirely... Oracle absolutely didn't stop work on ZFS, I'm not even sure where he came up with that nonsense. Oracle continued to update and release new versions of ZFS long after the lawsuit was settled. You know what's far more telling? 13 YEARS after starting BTRFS: Oracle uses ext4 as their default filesystem, not BTRFS. Redhat has dropped support for BTRFS entirely. https://fossbytes.com/red-hat-deprecate-btrfs-filesystem-stratis/ https://fossbytes.com/red-hat-deprecate-btrfs-filesystem-str...
