Move a Proxmox VM disk between storages with the GUI or qm move-disk: live vs offline moves, changing disk format, deleting the source safely, and common gotchas.
Grow a Proxmox VM disk safely: resize it in the GUI or with qm, then expand the partition and filesystem inside Linux or Windows guests. Why shrinking is the hard part.
Add an NFS share to Proxmox VE: configure the export, add it under Datacenter > Storage, pick content types for ISOs, backups, and disk images, and fix mount problems.
Fix a full Proxmox local-lvm: see why the thin pool fills, check usage with lvs and df, delete unused disks and snapshots, move storage, and stop it recurring.
Compare Proxmox storage options: LVM, LVM-Thin, and ZFS. How each handles thin provisioning, snapshots, RAM/ARC use, and performance, plus which to pick for your setup.
How VMware snapshots and delta disks really work, why they grow and slow your VMs, the 72-hour rule, and why a snapshot is not a backup. Practical guidance.
Bind mount vs named volume in Docker: how they differ, when to use each, where data lives, permissions, backups, and the down -v data-loss trap.
