Dear Raid experts, I have a soft RAID5 volume and after one disk failed I replaced it with a new hard-disk. Then the raid5 volume begin to resync with WHOLE new disk. There is only 1G data in the RAID5 volume so I think resync whole disk is not efficient. Take ZFS for example, when replacing with a new disk, it only resync the data which are written after the creation of the volume. Is there any method to just resync WRITTEN data to new-added-disk ? Or any developing plan to add this feature? ________________________________ This email (including any attachments) is confidential and may be legally privileged.
