How to Add Extra Storage to an LXC Container in Proxmox VE (Mount Points Explained)
Learn how LXC mount points work in Proxmox VE and how to attach extra storage to a container through the GUI or the pct command, including bind mounts and resizing.
Why Is Your Proxmox VE Storage Full? How to Check Disk Usage and Free Up Space
Proxmox says your storage is nearly full, but the numbers don't add up? Here's why local-lvm's usage bar lies to you, how to check real disk usage with pvesm status, lvs, and zfs, and how to safely free up space.
Proxmox VE Storage Types Explained: Directory vs LVM vs ZFS vs Ceph (Which Should You Use?)
Proxmox VE offers eight different storage types and the Add Storage dropdown doesn't explain any of them. Here's what Directory, LVM-Thin, ZFS, NFS, and Ceph actually do, and how to pick the right one.
How to Mount an SMB/CIFS Share as Storage in Proxmox VE
Got a Windows share or a NAS with SMB enabled? Here is how to add it as storage in Proxmox VE step by step, using both the web interface and the command line, plus the settings and errors that actually trip people up.
How to Set Up Storage Replication Between Proxmox VE Nodes (ZFS-Based, No Shared Storage Required)
Configure ZFS-based storage replication between Proxmox VE nodes from scratch using the GUI and the pvesr CLI — schedules, bandwidth limits, and how it pairs with HA for fast failover without a SAN.
How to Move a Virtual Disk to a Different Storage in Proxmox VE
Learn how to relocate a VM or LXC disk to different storage in Proxmox VE using the GUI's Move Storage option or the qm disk move and pct move-volume commands, live and without reinstalling anything.
How to Add iSCSI Storage in Proxmox VE (With LVM on Top for VM Disks)
Connecting Proxmox VE to a SAN over iSCSI is only half the job — a raw LUN can hold just one VM disk. This guide shows how to add the iSCSI target and layer LVM on top so you get real shared storage for VM disks across a cluster.
Proxmox VE Disk Image Formats Explained: Raw vs qcow2 vs VMDK
Raw, qcow2, and vmdk look like an arbitrary dropdown when you add a VM disk in Proxmox VE, but each one trades off snapshots, thin provisioning, and I/O overhead differently. Here is what each format actually does, which storage backends support them, and how to convert between them without guesswork.
Understanding Proxmox VE Disk Cache Modes: Write Back, Write Through, None, and Direct Sync Explained
Learn what each Proxmox VE disk cache mode actually does at the QEMU level, why ZFS needs Direct sync instead of the default, and how to choose safely between No cache, Write back, Write through, and Write back (unsafe) without risking data loss on host failure.
