Hello again, I''m wondering if we can see the amount of usage for a drive in ZFS raidz mirror. I''m in the process of replacing some drives but I want to replace the less used drives first (maybe only 40-50% utilisation). Is there such a thing? I saw somewhere that a guy had 3 drives in a raidz, one drive only had to be resilvered 612Gb to replace. I''m hoping as theres quite a bit of free space that some drives only occupy a little and therefore only resilver 200-300Gb of data.

A raidz vdev is auto-balancing, and effort is made to spread data across as many devices as possible. Unless access patterns are a weird, each drive should hold the same amount of data within a reasonable margin of error. -B -- Brandon High : bhigh at freaks.com
