I did this on Solaris 10u3. 4 120GB -> 4 500GB drives. Replace, resilver; repeat until all all drives replaced.

Hi All, My mate Chris posed me the following; rather than flail about with engineering friends trying to get a "definitive-de-jour" answer, I thought instead to introduce him to the relevant opensolaris forum in the hope of broadening the latter's appeal. So: RAID-Z hot swap to larger disks and thereby upgrade? Doable, not, or unwise? I suspect the proper thing to do would be to build the six new large disks into a new RAID-Z vdev, add it as a mirror of the older, smaller-disk RAID-Z vdev, rezilver to zynchronize them, and then break the mirror. But I'd like a second opinion? - alec >Hiya Alec, > >Mark Baily here at VPAC asked me a ZFS question which I can't answer >(except by guessing) and I said I'd ask you in case you had a quick >answer as you've played with it a bit more. > >Mark wrote: > >> Can the pool's size be increased by replacing [6 old 320Gb disks] >> with a new set of 6 HD's say 640GB each, changing one disk at a >> time and waiting for data to be resilvered before replacing the >> next disk, then when all 6 disks are resilvered the size will >> automatically be doubled? > >My guess is that the answer would be yes, that should work, but that >is just a guess!
