July 15Jul 15 Sorry if this was answered in the forums before, but I wonder if there is a difference in where and how ZFS Compression is set.So I added a single SSD to the pool and turned on Compression on the disk (I left the name as Cache from when I was using Unraid array parity + ssd cache, not a great name). But I noticed when I created a dataset on the cache pool, I could set the compression for the dataset, which I choose zstd.So which compression algorithm is being used when I write things to the zfsCache dataset? And is it doing compression twice? Does the compression setting in the dataset take precedence over the compression setting in the pool?I assume it is zstd, and any new datasets created on that pool will use the default unless a compression algorithm is specified.Sorry if my questions seem dumb or if I'm overthinking it.
July 15Jul 15 Community Expert Solution The compression you set for the pool will be the default for any dataset you create there; it will be inherited, but if you create a dataset using a specific compression, that is the one used (instead of inheriting the pool default)
