Xe138 Posted May 28 Posted May 28 From what I understand, Unraid support expansion of a ZFS pool by adding a vdev of equal width as the original vdev. I can't find documentation on exactly how this is done, so I want to ask here before I invest in the drives. I currently have 4x10TB drives in an unraid array that are nearing capacity. My plan is to install 4x16TB new drives as a new ZFS pool (RAID-Z1). After moving the data from the unraid array onto this pool, I intend to repurpose the 4x10TB drives as a ZFS vdev to expand the 4x16TB pool. Does unraid support this? What is the process in the unraid UI to perform this expansion? Quote

Yes, but 6.12 has bug where it won't allow you to add a vdev made of smaller devices, that won't be an issue with 6.13, but for now you would need to do it manually and then re-import the pool. 7 hours ago, Xe138 said: What is the process in the unraid UI to perform this expansion? Just add 4 slots to the pool, assign the new devices and start the array, but like mentioned, with 6.12 it will only work if the new disks are same size or larger. Quote
Xe138 Posted July 16 Author Posted July 16 Following up on this now that Unraid 7 is released in Beta and it's prime day. Will vdevs made of smaller devices be supported in Unraid 7? Quote
