How to Resize a Virtual Disk in Proxmox VE (Linux and Windows Guests)
Learn how to grow a VM's virtual disk in Proxmox VE and extend the partition and filesystem inside Linux and Windows guests so the extra space is actually usable.
Configuring Redundant Corosync Links for Proxmox VE Cluster Resilience
A single corosync link is a hidden single point of failure in every Proxmox VE cluster. Here's how to diagnose link instability and configure a second, truly independent corosync link using knet.
How to Mount an NFS Share in Proxmox VE (Add NFS Storage Step by Step)
A beginner's guide to adding NFS network storage in Proxmox VE, covering the GUI and pvesm command-line methods, what each field means, and how to fix common mount errors.
Configuring SR-IOV for High-Performance VM Networking on Proxmox VE 8
Virtio-net hits a wall under sustained high-throughput or latency-sensitive workloads. Here's how to enable SR-IOV on Proxmox VE 8 so VMs talk to Intel NIC virtual functions directly, bypassing the host data path entirely.
How to Set Up Email Notifications in Proxmox VE (SMTP Targets)
Learn how Proxmox VE's notification system works, and set up SMTP targets and matchers so backup failures and system alerts actually reach your inbox.
Recovering From LVM-Thin Metadata Exhaustion on Proxmox VE
A Proxmox VE thin pool can hit 100% metadata usage while data space still looks fine, sending VMs into read-only I/O errors. Here's how to diagnose it with lvs and dmsetup, fix it live with lvextend, and stop it from recurring.
How to Reset a Forgotten Root Password in Proxmox VE
Locked out of your Proxmox VE host? Learn how to reset a forgotten root password using GRUB recovery mode, a live-CD fallback, and the separate process for LXC containers.
How to Mount an NFS Share as Storage in Proxmox VE
Learn how to export a folder from a NAS or Linux server and mount it as NFS storage in Proxmox VE, so you can store ISOs, backups, and templates without filling up your host's local disk.
Diagnosing and Fixing Failed Proxmox VE Storage Replication Jobs
ZFS-based replication keeps Proxmox VE HA working without a SAN, but jobs fail quietly from broken snapshot chains, renamed storage IDs, and full target pools. Here's how to read pvesr's errors, find the real root cause, and trust the GUI again.
