I first built my NAS about 6 or so years ago. My original volume was a RAIDZ-1 with four 3-TB drives. I am wishing to upgrade this volume with, probably, 6-TB drives. I don't want to lose any of the data or have to change any significant settings and curious how to do this in the best fashion. Can I re-silver one 3-TB drive with a 6-TB drive, one at a time and then take advantage of the double capacity? I have only re-silvered drives when there was a failure, not when I was wishing to upgrade. I just get anxious anytime I mess with this and want to make sure I do my homework and know what to expect before I do.
This machine has been somewhat of a "Winchester Mystery House" of a NAS. All of my volumes are in four-drive RAIDZ-1 arrays. I know it could be done more efficiently with more drives per volume, but I can only justify at certain price-point increments. The first volume is four 3-TB drives, the next two volumes are four 4-TB drives each. The fourth volume is four 6-TB drives. My hope is to upgrade Volume 1 to four 6-TB drives without losing data or having to make numerous changes elsewhere. I still have capacity in the machine for four more drives after that, but I'd rather have migrated the first volume to larger drives first.
