> zstd is now standard and the default on openzfs 2.0, replacing lz4. Are you sure? The default compression level has always been "off", but when switched on - the default has been lz4 for about 5 years. Zstd support was added less than a year ago and there are still a lot of things that need to be fixed before one could even suggest that it might be a sane default. I like zstd, but I like my uncorrupted data more. I know that compatibility between compressor versions and pools is a concern, and there are also the compression performance problems with the way zstd handles zfs block sizes. Thankfully lz4 works great for zfs and has for many years now. https://github.com/openzfs/zfs/blob/master/include/sys/zio.h... |
