January 15, 20251 yr Community Expert Due to current pricing of drives, it seems to be a better choice to get larger drives than I currently have, than buying more of current capacity. - Currently I have 18TB drives in each vdev, all the same. - I am looking at having to change to 20TB drives. Which is the correct method? 1) Create new pool, so that vdevs within each pool are the same size. 2) Create a new vdev within the current zfs pool, with all size 20TB. (still noting that all the other vdevs have 18TB). Thank you to any help!
January 15, 20251 yr Author Community Expert raidz1 - 6wide vdev *Note, I am also considering dropping to 16TB as well, as any potential resilver would benefit from smaller size.
January 15, 20251 yr Community Expert Solution You can add a new vdev with 20TB drives, though raidz1 with 20TB drives, or even 16TB, can be considered risky, but it will depend on the backup situation.
January 15, 20251 yr Author Community Expert @JorgeB As always, thanks for all the help! Good to know that as long as the vdev has same size drives, I'm ok to add to current pool. I agree with the risk for sure. I would not use this layout with most setups. However, this is all media storage and completely replaceable via other backups/locations. (and not time sensitive to recreate if needed)
