I have few questions regarding qtree, volume and raid group
- Is it ture that raid group is added to a volume automatically?
A raid group is created automatically when you add new disks to a volume and fill the current raid group.
- is there any command for creating new raid group?
No. When the current raid group is filled, a new raid group is created automatically.
- when a qtree is created on a multi raid group volume, does the qtree span
across all raid group? do you have control on which raid group the qtree can reside on?
I don't think you have control over what raid groups a particular qtree can use.
- when the max disk per raid group is increased, does it affect all raid
groups?
I believe it only affects the current raid group.
- I know if a new disk is added, it will be added to the last raid group of
a volume. Assuming the answer to Q4 is yes, then what happen if the last raid group of a volume is filled and there exists raid group(not the last one) in the same volume that is not filled?
See 4).
