Hope smeone can give me an answer.
We have a filer with 14 disks and one aggregate aggr0, the raidsize =20
so this aggregate has only one rg for now with 14 disks.
I want to add more disk to that aggregate but do not have same size , this case, I am thinking of creating new raid group. by doing this (I never did this)
> aggr add aggr0 -g new -d <disk1> <disk2> , etc (total 7 disks)
1. Will this put the all 7disks in the new raid group or add the disks in th existing raid group ?
2. If that create new raid group for he 7 disks, Can I increase that raid group later when I have more disks, that is, from RG7 to RG=20?

How do I increase the disk count on that raid groups ?
RAID group /a_aggr0/plex0/rg0
RAID group /a_aggr0/plex0/rg1
rg0 has 14 disks
rg1 has 7 disks
I will appreciate if you can post me the comand ?

If I understand well, you have an aggr with 14 disks and one RG. You want to add 7 disks, but you want to create a new RG.
If you want that, you should reduce the RG size on this AGG to 14 and add those 7 disks. This will create a new RG with 7 disks.
But using that AGGR with that unbalanced RG size configs is not recommended. If this are SAS or FC disks I would go with RG size=21.
