Hello,
I have a 2-node Proxmox cluster with only local storage (no shared storage, no Ceph, no replication).
Configuration on each node:
- ZFS pool: local-zfs (rpool/data) used for VM and containers
- "local" storage (dir /var/lib/vz) used only for backups and ISOs
- Both storages are located on the same physical disk
Real capacity:
- Node1 ≈ 500 GB
- Node2 ≈ 1 TB
- Real total ≈ 1.5 TB
Problem:
In the Datacenter → Summary dashboard the total storage is shown as about 2.5 TB, which is higher than the real physical capacity.
Checks already done:
- No duplicated entries in storage.cfg
- Each node shows the correct local capacity when viewed individually
- The issue appears only in the aggregated cluster view
- "local" and "local-zfs" are backed by the same physical disk
It looks like the dashboard is summing both storages even if they share the same underlying disk.
Question:
Is this behavior expected/by design in Proxmox, or is it a dashboard bug?
Is there any way to avoid double counting while keeping "local" for backups?
Thanks.
