FAS2554 root data partition configuration

Hello all,

 

Is it possible to configure a cluster with root data partition, where all data partitions belong to one aggregate but the root partitions are split between the  two root aggregates?

Example: FAS2554 with 20 disks, 10 root partitions for root_aggr_01, 10 root partitions for root_aggr_02, 20 data partitions for data_aggr_01.

 

Assuming this is possible, what would be the best way to achieve this, starting with the typical root data partition configuration:

-10 root partitions for root_aggr_01 + 10 data partitions for  data_aggr_01.

-10 root partitions for root_aggr_02 + 10 data partitions for data_aggr_02.

 

Can I delete the "data_aggr_02" and the add these data partitions to  "data_aggr_01" ?

 

Thanks for your help,

Pedro

Yep.   You need to remove the owner of the data part of the partition and the assign it to the partner.   

 

set adv 

disk removeowner -disk x.x.x -data true
disk assign -disk x.x.x -data true -owner NODEx
disk show -fields data-owner, root-owner

Make sure you reallocate after you do so, otherwise you might experience less performance (depending on # of disks added). https://kb.netapp.com/app/answers/answer_view/a_id/1001574/loc/en_US

I usually recommend to customers to do a "reallocation start -f true -p true -path /vol/volumename" and do one volume in the aggregate at a time. Usually that is enough to balance it out. Start from your busiest volume that may be the smallest and work your way to more idle volumes.
