If one asks for a paste of pool + dataset properties, it’d show if compression and or duplication are on, and ashift/recordsize. Even atime would show up.
I guess suggesting it be wrapped in the spoiler tags would help reduce visible post length
If you are running sync workloads like serving NFS sharing or virtual machines consider the usage of a SLOG dedicated SSD. A ZIL dedicated device greatly decreases the possibility of fragmentation.
Having a SLOG device will also increase NFS sync write performance. So if you are having performance issues with NFS writes into a ZFS volume you might want to do that or use async in case you don’t care about the data.
