Hey guys! Not sure where to ask this, but I was reading up on - somewhere, can’t seem to remember where! - the potential to have different size disks in a ZFS vdev as a possible future feature. At least I think I read it correctly. It was a late night pre-bed on my phone read and I didn’t save the link and just forgot about until tonight.
I know synology and other file systems have the ability to do this, but ZFS does not. I can’t quite come up with the search terms to hunt this down again as the vast majority of results from any combo of “ZFS” and “different size disk” returns “no it’s not supported”. I just swear I read there is a possibility of it being introduced in a future version? Or it’s current being worked on as beta only? I can’t remember, just looking for info :)
*edit to clarify - I know you can use different size disks in a vdev with the restriction of the smallest drive size x n-drives being the limiting factor on vdev total usable space. Looking for info on combining different size drives in a vdev and using all of each of the drives space, while still maintaining parity; say a vdev of 10 4TB drives and 2 10TB drives in Z2, and having, well, some amount more than 40TB of formate usable space.
