Hello people!
I have a question about implementing Raid 10 in FreeNAS. It says the following on the wiki:
Does this mean that if I create a mirror volume of 2 drives and extend it with a second mirror volume with two drives, it effectively becomes a Raid 10?
I have a question about implementing Raid 10 in FreeNAS. It says the following on the wiki:
Once a vdev is created, you can not add more drives to that vdev; however, you can stripe a new vdev (and its disks) with the same type of existing vdev in order to increase the overall size of the ZFS pool. In other words, when you extend a ZFS volume, you are really striping similar vdevs. Here are some examples:
- to extend a ZFS mirror, add the same number of drives. The resulting striped mirror is a RAID 10. For example, if you have 10 drives, you could start by creating a mirror of two drives, extending this mirror by creating another mirror of two drives, and repeating three more times until all 10 drives have been added.
Does this mean that if I create a mirror volume of 2 drives and extend it with a second mirror volume with two drives, it effectively becomes a Raid 10?
