WebbIMO the best fix would be to have do_verify() reset the seed back to the value when do_io() last ran rather than back to its job-init value. That allows us to keep the seed verification enabled for the mixed read-write workloads while still having per-iteration-unique generation for randrepeat=0. WebbThere are three possible approaches to handle the zero RPO requirement: Ask your storage or data service to replicate the data synchronously in a recovery site. Don’t try to fulfill the requirement completely but reduce the intervals between each backup.
