Hi Fred:
I do. I have 3 pools. system, ssd data pool(fc_ssd400G) and a spinning
disk pool(fc_8T).
I want to think the ssd_data_pool is empty at the moment and the system
pool is ssd and only contains metadata.
[root@cl005 ~]# mmdf home -P fc_ssd400G
disk disk size failure holds holds free KB

More or less empty.
Interesting...
