    What's needed to access my VM using hostname.local instead of IP?

    I have the latest version of Proxmox with a few containers and VMs and was wondering what if required for the other machines (Linux and Mac) to be able to reach these containers and VMs using `hostname.local` instead of using their IPs. On a Mac, you can tyrpically use the `hostname.local`...

    [SOLVED] ZFS: Cannot replace a FAULTED disk, every new disk becomes FAULTED too in a RAIDZ2 rpool

    I'm having trouble replacing a FAULTED disk in my ZFS RAIDZ2 rpool. I have now bought 2 disks to replace the 1 that is FAULTED, but during the resilvering process, the new disk becomes FAULTED as well. At first I thought this was a coincidence and throught the new disk must've been damaged...

    Rescue Mode: Black screen, nothing happens?

    I am trying to get into Proxmox rescue mode to fix a few ZFS issues, but when I select "Rescue Mode" when booting from a USB stick (latest Promox version), the screen remains black. I think I can hear disk activity, but nothing appears on the screen. Should I wait or... ? I have used rescue...

    Proxmox ZFS won't boot anymore after degraded disk

    I have Proxmox 6.2 with 6x 6TB disks in a RAID-Z2 configuration. Since a few days ago disk 3 failed and the rpool was degraded. I replaced the faulty disk with another identical one, but after a few hours I got the message that this disk was also faulty. The resilvering process did continue...

    Getting filename of a single backup created with vzdump --dumpdir

    With vzdump 100 --dumpdir --mode stop I can dump a single VM to a dir, but how can I know the resulting filename of that dump? The man page does not tell anything about the output of vzdump This is to be used in a bash script, so it should be non-interactive. I already know about the backup...

    Fresh installation with ZFS crashes when restoring 1st VM from backup

    I just installed the latest version of Proxmox (version 6.2-4), using ZFS RAID1. Installed a few tools for ZFS, like auto-snapshot en ZFS-ZED, setup a zfs-auto-snapshot schedule in /etc/cron.d/zfs-auto-snapshot and enabled Let's Encrypt, nothing else (so you see I did very very little to the...

    Discard / Trim for SSD disks

    I noticed that the `Discard` (sometimes called `Trim`) option is turned off by default. This is needed to keep backups smaller as disk space can be reclaimed on SSD disks. I'd like to understand: - Why is the Discard option disabled by default? - Can't Proxmox auto-detect if the underlying...

    VM backup fails for unknown reason as of today?

    Starting today, backup up a VM fails on our Proxmox host. I have no idea why and see no clear cause. The disk is not full and the VM is very small. It has worked every time before. This is a single server (no cluster) and the backup of the small VM is saved locally. The filesystem is ZFS...

    Webhook support, like at the end of a backup?

    I know there has been a few threads on running a script after a backup, but I want to ask 1 specific thing. Can we trigger a webhook and send it the details of the backup in a JSON or XML format? Is there structured data available somewhere we can easily HTTP POST or do we need to code the...

    Total system freeze, how to debug?

    I have a single machine running the latest Proxmox (recently updated it too), but it freezes completely about 1x per month. The machine is a very simple setup (no cluster) and runs our office software. Some limited downtime is not a big problem. This machine has: - ZFS - 6 WD Red drives - Intel...

    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.

    Migrating from a single machine setup to another single machine setup

    We currently have a single machine Proxmox setup with 1 VM inside. The hardware is getting old and needs to be replaced. Typically, we would: 1) Prepare the new machine 2) Stop the VM on the old machine 3) Backup the VM 4) Transfer the VM 5) Start the VM on the new machine 6) Change all the IPs...

    Create a VM on ZFS storage without having an ext4 filesystem on top of the ZFS host filesystem

    Is it possible to create a VM on underlying ZFS storage, and not have the VM format it's disk as ext4 but instead use the zvol directly? Thus avoiding a filesystem on filesystem situation... Just wondering if this kind of thing makes sense and is possible so ZFS can be put to optimal use.

    Oops, no VM backups because pve-root is full!?

    Oops, turns out I have no backups since many months due to pve-root filling up during the backup process and it eventually fails. My disk is: pve-root: 90 GB pve-data: everything else I have 1 critical VM running. How can I address this issue safely? Honestly, I'm a bit new to Proxmox and...
