Storage
The Storage page provides a unified view of all storage backends configured across your connected Proxmox nodes. Monitor capacity, usage, and content types from a single dashboard.
Storage Overview
The overview dashboard displays all storage endpoints detected from your Proxmox infrastructure. Each storage entry shows:
- Name — The storage identifier as configured in Proxmox
- Type — The storage backend type
- Node — Which Proxmox node(s) the storage is available on
- Status — Whether the storage is currently active and accessible
- Usage — Visual progress bar with total, used, and available space
Supported Storage Backends
ProxCenter recognizes and displays all storage types supported by Proxmox VE:
| Type | Description |
|---|---|
| Local | Directory-based storage on the node's local filesystem |
| NFS | Network File System shares mounted on nodes |
| CIFS/SMB | Windows-compatible network shares |
| ZFS | ZFS pools and datasets, including ZFS-over-iSCSI |
| Ceph RBD | Ceph RADOS Block Devices for VM disk images |
| CephFS | Ceph Filesystem for shared file storage |
| LVM | Logical Volume Manager block storage |
| LVM-thin | Thin-provisioned LVM volumes with snapshot support |
| PBS | Proxmox Backup Server targets for backup storage |
| iSCSI | iSCSI targets for block-level network storage |
Storage types are detected automatically from your Proxmox node configuration. No additional setup is needed in ProxCenter.
Storage Metrics
For each storage backend, ProxCenter displays the following capacity metrics:
- Total — The total provisioned capacity of the storage
- Used — How much space is currently consumed
- Available — Remaining free space
- Usage percentage — A visual indicator showing how full the storage is
Keep an eye on storage backends exceeding 85% usage. Running out of disk space on a Proxmox node can cause VM failures and data corruption.
Content Types
Proxmox storage backends are configured to hold specific content types. The Storage page shows which content types each backend supports:
| Content Type | Description |
|---|---|
images | VM disk images (qcow2, raw, vmdk) |
rootdir | Container root filesystems |
vztmpl | Container templates |
iso | ISO images for VM installation media |
backup | VM and container backup files |
snippets | Configuration snippets (cloud-init, hookscripts) |
Each storage entry displays badges for the content types it is configured to accept, making it easy to identify where to store specific resources.
Per-Node Storage View
You can filter the storage list by Proxmox node to see only the storage backends available on a specific hypervisor. This is particularly useful in environments where:
- Nodes have different local storage configurations
- Shared storage (NFS, Ceph) is not available on every node
- You need to plan a VM migration and want to verify storage compatibility on the destination node
Permissions
Access to the Storage page requires the following RBAC permission:
| Permission | Description |
|---|---|
storage.view | View storage backends, their configuration, and usage metrics |
Users without this permission will not see the Storage entry in the sidebar.
