T3 Truenas Youtube REALLY needs to get on this topic.
Enough about L2ARC, BUY/CONFIGURE RAM.
I do have a ZFS/TRUENAS request though.
MOST of the confusion (As I see it in this post even) is derived by the combination of the indexing of the pool and small files on the same device.
MAYBE we should be looking at separating the indexing and the small files the way you currently tackled the SLOG.
What a wonderful and streamlined world it would be, if rather than manually predicting the file sizes and saving them to the correct/speed pool/vdev….
We have the algorithm(s) responsible for small-block-size assignable all on their own to their own pool. Ya I know I stepped out of the pool (box), Maybe we can figure out a way to accomplish the same thing without stepping out of the pool/box?
Anyways… SERIOUSLY prudent post and I am happy I got to learn from it.
Cheers.
Drop Kris and I a line - t3@truenas.com - and we’ll see if we can do a viewer-questions heavy show. There’s several caveats around sVDEV use (as this thread’s existence speaks to!) and using it safely.
Didn’t realize you were Chris from T3
Wasn’t gaslighting. I swear.
