About 5 years ago I bought three drives for my ZFS pool on my ubuntu NAS box. Got everything setup and running and have been using it for the past five years with no issues. Mostly bulk storage for photos and movies, but also ran a Plex server for a while (not anymore). It is a RAIDZ1 with 3x 6TB WD blues.

Recently I setup a 3 node proxmox cluster of mini-pcs and was looking at using the ZFS box for shared storage, not CEPH, just shared storage for the cluster. Doing some research I found out about my mistake five years ago with the SMR drives and why that might be an issue.

I picked up 3x 8TB CMR drives and am thinking I should be able to just replace them one at a time, then expand the storage. I'm wondering how 'dangerous' to the data this might be? If I understand the risks with SMR its more about when it is being resilvered, and in this case it would be used as a data source, not written to.

Is this a good idea? One at a time replacement? If not what are my other options to move my data/pool over to the new drives?
