Hi.
This week, I've been lucky(?!) enough that, despite two drive failures in my ZFS pool, I'm managing to save most of the data. I've brought a couple of 8Tb drives and am about half way through copying my data over to the new drives.
To save anything embarrassing in future, I want to make the pool more redundant. All the research I am doing suggests that mirroring is better than RAIDing, certainly in a home environment.
However, despite my research, I am still confused on a couple of points.
What I want to do is this:
5 * 3Tb HDDs in a VDEV mirrored to 2 * 8Tb HDDs in a seperate VDEV, all in one pool. Where I am getting confused is, it seems that in posts such as this one (https://dawning.ca/2017/freenas-11-add-a-drive-to-create-a-mirrored-zfs-volume/), the instructions seem to be mirroring disks in a one-to-one relationship, rather than mirroring across VDEVs?
Is my plan possible, or would I be better off just having two pools and syncing the data between them? Maybe via snapshots?
Thanks,
Kai
