Hello Pedro,
Not exactly. The procedure is:
Parent FlexVol Vol1
Clone Vol1 to Vol2
Remove All Qtrees from Vol2 I do not want to have on clone.
Split the clone.
I am actually running it now. It is working. Vol1 is about 90 TB.
I deleted about 50TB worth of qtrees. Then I split the clone. It is only copying the 40 TB as I was hoping it would.
The reason I was trying to do this is that the clone split itself is painfully slow. I found that in many cases not just this, it is hardly usable. Contrary using snapmirror or snapmirror restore is blazing fast so I am using those.
I was thinking that the slowness us because the clone being limited to the same aggregate whereas snapmirror is not.
Thanks Pedro for your insight.
kind regards,
Bela
