my main zpools (4x1TB in RAIDZ1) are about 70% full. I probably should start thinking about replacing the drives with 4x2TB soon...or deleting some crap.
2*4TB would give you twice the storage you've currently got with less noise and power use. 3*4TB in a RAID-Z1 will give you 3* the storage you've currently got. How do you replace a zpool? I've got a system with 4 small disks in a zpool that I plan to replace with 2 large disks. I'd like to create a new zpool with the 2 large disks, do an online migration of all the data, and then remove the 4 old disks. Also are there any issues with device renaming? For example if I have sdc, sdd, sde, sdf used for a RAID-Z1 and I migrate the data to a RAID-1 on sdg and sdh, when I reboot the RAID-1 will be sdc and sdd, will that cause problems? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
