It would be great if you script would be able to deal with pools with = broken labels. I will put the three 3TB disks aside and use the old = 1.5TB disks instead. So if there is some progress in your script or = someone else is gonna write some tool for restoring labels or reading = data of broken pools, perhaps I can get some data back. I think it would = take some time to get this fresh 3TB pool full ;-) This would also solve the next problem I discovered... These 1.5TB disks have 512byte sectors. I have one spare. If the second = disk falls out, first I thought, I will replace it with a 4TB disk and = so on until I have replaced all of them. So I can expand the pool. But = as I read now, this is not possible, isn't it? Because the 4TB drives = would have 4k sectors.
