If fio is run against a zoned device that has any zones in OFFLINE condition, the following assertion is raised - fio: zbd.c:473: parse_zone_info: Assertion `z->wp <= z->start + zone_size' failed. This happens because offline zones have no valid write pointer and it is reported by libzbc and blkzoned as (uint64_t)(-1). To avoid violating this assertion, set the write pointer in all offline zones to point at the start of the zone.
