1. Aggr0 has total space of 3.5TB. Correct?

2. How much space is available in vol0? I think it should be around 600GB, but why the df -h command shows only around 176GB?

Thank you.

sorry my mistake, it was a typo:

snap sched -A aggr0

snap reserve -A aggr0

If you decide to claim back 186g you can run

df -Ag aggr0

snap reserve -A aggr0 0

df -Ag aggr0                     > see that free space increased.

To fix your issue you can increase vol0 size. > vol size vol0  new _size
