Proxmox 6.4-13 says I have more storage than I really do?

[SwissHomeLabber]

I have 2x servers each with 8x 3.84TB Enterprise SSDs in raidz2, with ashift set to 13.

Proxmox version is 6.4-13. (I'm doing an update as I write this post)

They are configured in a two node cluster (I haven't got a third node, yet!)

On the node status pages,

Box #1 reports 18.03TiB usable space in root. This box has Micron 5100 Eco SSDs.
Box #2 reports 17.71TiB usable space in root. This box has Samsung PM863a SSDs.

On the overall cluster status page, the cluster says I have 71.75 TiB overall usable space.

Does anyone have any ideas of why these numbers don't add up correctly?

can you post your '/etc/pve/storage.cfg' ?

by default the dashboard sums up all 'shared storages' once and all 'non-shared' storages for each node, but
you can manually select which storages are counted in the 'settings' window under the user menu on the top right

Node 1:

root@node1:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

zfspool: local-zfs
        pool rpool/data
        sparse
        content images,rootdir
root@node1:~#

Node 2:

root@node2:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

zfspool: local-zfs
        pool rpool/data
        sparse
        content images,rootdir
root@node2:~#

ah ok, that make sense... both the storage 'local' as well as 'local-zfs' point to the same underlying zpool so it gets counted twice
simply configure the storages as i said in the gui, then it should get calculated correctly
