You gradually replace one disk at a time, resilver then repeat. ZFS automates most or all the work mentioned in this article and it comes with built-in bitrot detection.
Btw I have run a NAS similar to this machine for 6 years now using FreeNAS. It’s awesome.
- shock 6y agoSo if I have 4x4TB drives and switch a drive so it's now 3x4TB + 1x6TB, and do the resilver, will the ZFS capacity be increased by 2TB?
- hestefisk 6y agoNo not until you have replaced them all.
- shock 6y agoIn that case, I don't understand why you replied to my comment asking "How would you migrate from 4 x 4TB to 4 x 6TB disks by buying one disk at a time?". In case it wasn't clear, the buying one disk at a time aspect is important, because storage needs increase steadily over time, not all at once, so it makes financial sense to buy a higher capacity drive and replace a lower capacity one over a longer period of time, instead of replacing all drives at once and then have most of the extra storage sit there unused.
