recordSizeKib

Specifies the record size of an OpenZFS root volume, in kibibytes (KiB). Valid values are 4, 8, 16, 32, 64, 128, 256, 512, or 1024 KiB. The default is 128 KiB. Most workloads should use the default record size. Database workflows can benefit from a smaller record size, while streaming workflows can benefit from a larger record size.
