NominallySavvyTechPerson Posted March 23 Share Posted March 23 (edited) IIUC if I want snapshots of a share, I can format one array drive as zfs and limit the share to that drive. If I want more space than that, can I make a zpool out of two zfs drives in my unraid array? That way, I can snapshot the zpool and have a snapshot of the share even though the share is too big to fit on one drive. I wouldn't use RAIDZ and would rely on unraid's parity to give some protection. Is that a good idea? Thanks! Edited March 23 by NominallySavvyTechPerson Quote Link to comment

Sorry, that went over my head. I found this where someone talks about adding a zpool to the unraid array. I'm not trying to add a zpool to the array... wait, am I? I was thinking that there was a difference between adding a whole zpool of drives as if it were a single slot in unraid (not supported) vs what I want to do where I would fill two slots in unraid with two drives. Then, unknown to unraid, I can make a zpool out of the two drives. Quote Link to comment

NominallySavvyTechPerson Posted March 23 Author Share Posted March 23 Oh, maybe I understand now. Unraid looks at each drive and opens the filesystem there and merges them together. If I made a zpool out of two of them, I wouldn't have a filesystem on either of the two drives. Unraid would just ask me if I wanted to format the drives because they don't have any filesystem.

NominallySavvyTechPerson Posted March 23 Author Share Posted March 23 Ok, I think I see. What I should be asking is "can I add a zpool to unraid" which is already asked in that post that I linked to. Quote Link to comment
