Hi all,

In my experience I think is not possibile but a customer of mine has this issue. He wanted to extend the two raid group of his aggregate but once increased the raid group size he forgot to use the syntax:

aggr add -d x.y -g raidgroup name

So the last raid group has been extended and another raid group has been created with only 5 disks... He asked me how to go back and my answer is: "Copy the data, destroy the aggr and recreate it..." :)

But I remember that times ago a customer of mine used the "disk fail" command just to try it and (not sure on syntax) he was able to "unfail" the disk. So, what, for this case, if "disk fail" is used to fail the disk, rebuild its data on a spare, the unfail the failed, zeroed and manually assigned to the right raid group?
