How much free space in my pool?

Hi, I created a zpool composed of 4 disks (Raidz2) totalling ~3.6tb.

Now as you can see in the following capture, the header of the grid says 155.13Gb used / 91.73gb free. Is this correct?

This system is a TrueNAS-13.0-U6.3

What does the dashboard show for your pool free space? You are showing three zvols, what size did you create them as?

It would help if you gave them an ‘alias’ on your screen shot so we would know what to refer each one as since you redacted their names.

Output of zfs get -r refreservation Backup please.

Thank for your responses. As I was in a hurry, and this is a new system I wiped everything out and started from scratch, now it works as expected.
