Not sure I follow- before the change, RG1 had 12 and RG2 had 11, then you added 8 disks and now RG1 had 17 and RG2 has 14?
In any case, when you add disks to an aggregate, you should always preview the raid layout it'll build before committing the command.

Hello toasters,
A few weeks ago, I had the opportunity to destroy an aggregate in order to consolidate capacity. I started off with two aggregates, each with two RG and both aggr were 600GB drives only the older drives were FC/15K whereas the new aggregate is SAS/10K (I know you can mix RPMs and I’m ok with that). What I’m not ok with is what happened when I attempted to add 8 drives to the new aggregate. The current RG size was 12 and there were 12 drives in the first RG and 11 in the second, I then changed the RG size to 16 and added the drives to the aggregate (expecting to add 4 in each RG). But what really happened is that OnTap added 5 drives to RG1 and created RG2 with the remaining 3 drives.
Support couldn’t find any documentation on this and (I knew this) that it could only be corrected by destroying the aggregate. Have any of you experienced this?
Thanks,
Bill
