Proxmox WebGUI - ZFS storage size


New Member

I installed proxmox 5.3 in my lab, I testing it. My server have three hdd (sda, sdb, sdc). I installed proxmox the first (single) hdd (sda).
After installation, I made a zfs pool (zfs mirror - sdb, sdc), the pool name is xtank. The sdb and sdc hdds size are 2.7 - 2.7 TB, so the pool size is 2.7 TB. That's okay.
After that, I create two zfs filesystem:
zfs create xtank/vmdata (store my vm machines)
zrs create xtank/vz (backups, isos)

And in the webgui, Datacenter -> Storage -> Add -> ZFS: I added the xtank/vmdata
and the webgui, Datacenter -> Storage -> Add -> Directory: I added the xtank/vz

The proxmox GUI pve -> ZFS: show my pool xtank, the size is 2.7 TB, correctly.
But, the Datacenter -> Summary -> Storage show 5.6 TB size (2 x 2.7 TB + sda).

I create an test filesistem:
zfs create xtank/test

And I added the Datacenter -> Storage -> Add -> Directory.
Now shows the size 8.32 TB.

What do I do wrong?
Please help.

the Datacenter Summery does not know that this is all the same storage backend.
You can set what is count in the Summary at the Gear icon on the right top side.
This has avoided my attention so far. Thank you, that was the solution. Thanks!

How many TeraBytes supports Proxmox 3.4?
I would like to know if Proxmox has a limit in terms of TeraBytes
