  3. Operational issues with ZFS and pvesr

    Ever since Proxmox 6 came out, we moved towards using Proxmox with ZFS across all physical servers.

  14. Can I delete a dir from inside a .vma file?

    I have a VM backup that I want to restore, a .vma.lzo file. This file is huge because of an out-of-control process. Can I delete a dir from inside a .vma file and then restore the VM? Restoring the entire VM with all the unneeded data inside would take up way too much time.

    Hi, I'm have a backup-job scheduled which will daily backup my system. Sometimes while running the backup, the system will spawn one arc_reclaim and lots of arc_prune processes. All of these processes will eat up the CPU time and cause the VMs which are still running to run into (timeout)...

    Proxmox VM backup vs. wbadmin vs. [...]

    Hi, until now I've used wbadmin to backup Windows machines (no matter if VM or on real hardware). But now I've setup a Proxmox test machine and I've found the integrated VM backup feature which looks very interesting to me. Did a short test with a Linux guest, which worked flawlessly. But I...
