hello everyone, can you please advise on a few things:
1) https://www.truenas.com/docs/references/zfsdeduplication/
I see that Deduplication can use ARC/L2ARC and it can use SLOG?
2) in a normal situation De-duplication tables be stored in Metadata? or as a separate table?
3) I don’t understand for what exactly, in what use cases, Metadata may be needed?
4) I found 2 ssd disks, I wanted to use them for cache, but they seemed to be a little different size - 238.47 GiB and
232.89 GiB , it says to me - "Mixing disks of different sizes in a vdev is not recommended." -
a) Could I force VDevs? (for example, a mirror) and what will happen then? it will only use ~232GiB ?
b) or should I somehow cut off partitions of the same size with my hands and make VDevs already on these partitions?
5) can I make Data VDevs on it, make 2 Zvol, and then use them as Cache VDev (L2ARC) and Log VDev (SLOG)? or do I need to cut them into 2 sections, and feed them as devices?
