In journaling filesystems, builders seems to pick either "recover all filesystem transactions up to the point of crash" or "you may lose last few transactions", or make it an option (e.g. VxFS delayed log). Since snapshot-based file systems have 5+ seconds of interval for on-disk consistency, I was wondering how they respond on the issue.
It is not about performance issues either, since chosen approach of currency would impact performance accordingly. It is more about curiosity on what customers expect and builders provide about "currency" of recovery, since ZFS raised bar of reliability to detect silent corruption, self-healing, etc. I guess it stll remains as acceptance/preference/tradeoff issues.
