Problem ZFS disk usage show in popup menu and reality

[tex35]

Hello, I have just installed a datacenter with 6 nodes where in created a ZFS datastorage with the same name storage-local.
The problem is when i am looking in summary for this stockage in one node, the usage indicated is 98% but it's wrong because zpool list indicate 3.5 To/4.36 To



Please have you an idea ? it's seem to but a bug

How can we compare if you only show one picture? Show us the "popup menu" too. zpool status and zfs list will be helpful as well.
