Hello!
Happy and healthy 2021 to every and each one!
This is my story: I've just built a FreeBSD machine to use primarly as a NFS/ZFS home server. CPU is a Pentium G4560 (7th gen), case NAS 800, MoBo mini-ITX, 32GB ECC mem and 5x 4TB HDD Toshiba N300.
MoBo has only 6 SATA connections in total. The sixth is either SATA or NVMe, so I installed a Samsung NVMe m.2 240GB SSD. I selected UFS and accepted the install suggestion and used the whole drive (AutoUFS).
After learning about the L2ARC possibilities from ELI5: ZFS Caching (2019) https://papers.freebsd.org/2019/fosdem/jude-eli5_zfs_caching/
I would like now to assign a chunk of my SSD to L2ARC, so my question is how to shrink and add a L2ARC using my current boot drive (nvd0)?
I am planning having 128GB for L2ARC, if this makes sense.
Thanks a lot in advance!
