Hey all! New forum member here. I wanted to share my usage of ZFS on macOS for anyone interested -

I'm using:

- Mac Mini 8,1 (Intel) with 64GB RAM
- OpenZFS 2.1.0
- OWC ThunderBay 8
- 4x 10TB WD
- 4x 16TB WD

Currently using 4 vdevs each of which is a mirrored pair so the zpool currently totals ~52TB storage backing home labs and other storage. There are 5 datasets fo two ZVOLs formatted with APFS and exported over NFS (I'll migrate these back to ZFS datasets once the NFSv3 atime patches (which @lundman went to impressive efforts to find/fix) go into a followup release.

It's fairly vanilla, no compression or dedup enabled on any datasets, nothing too spicy.

I've taken the macOS version from 11.3 to 12.4 incrementally (skipped a couple versions in between) and haven't experienced any panics or other issues and the pool has returned to me after each OS update. Performance is stellar!
