March 19, 20242 yr Hello I currently have unraid setup with 4 zfs pools 1-4x2tb nvme zfs1 cache pool, 1- 2x1tb nvme zfs mirrored 1tb docker/vm pool, 1-8x8tb zfs2 backup pool, and 1-6x14tb zfs main pool. As I am running at 80% on my main pool I need to rebuild and expand it probably to a 10x14tb zfs3 but I'm out of drive bays on my case. I want to move my backup pool to another server then copy all the data back to my main storage. I'm wondering what files I have to copy off of the usb key to make this a simple move and startup on a new install.
March 19, 20242 yr Solution You should not need to copy anything from the flash drive, just assign the pool devices to a new pool on the other server, in the same order as zpool import/status. To send the data back, and if you have snapshots you want to keep, you can use zfs replication over ssh.
March 19, 20242 yr Author Thank you I'll give it a shot. I thought that should work just didn't want to try and somehow lose the data, its already going to take 24+ hours to move the data back.
