    Temporary mix PVE7 and PVE8 in the same Cluster

    Thank you for your fast replies! I don't think it's possible to "live migrate" with local (ZFS) storage. From my experience this is possible only with shared storage, but I might be wrong. So my plan was to shutdown/migrate/start. All hosts (old and new) are using AMD, so there's no mix between...

    Temporary mix PVE7 and PVE8 in the same Cluster

    Hey, I'm looking to upgrade all our hosts to better hardware and PVE8. The plan is to purchase the new hardware, add it into the current cluster, migrate all VMs from the PVE7 hosts to the new PVE8 hosts then shut down the PVE7 hosts. Please note that all VMs are stored locally (ZFS) so...

    [SOLVED] Please help me configure Hetzner's vSwitch with Public IP

    Hey, Glad that you found my tutorial useful. :cool: 1. Did you installed Proxmox from their original ISO or did you installed Debian and then "converted" it to Proxmox? 2. Are you sure that you've assigned floating IPs to the vSwitch, and not some static IPs?

    How to automatically remove backups from PBS when terminating VM from PVE?

    Got it, so the best scenario would be to avoid VMID re-use. Is there any "upper number limit" on VMIDS, for example 999? Thank you

    How to automatically remove backups from PBS when terminating VM from PVE?

    Hey, PBS+PVE default behaviour is that when a VM is terminated on PVE the backup will be kept on PBS, which is OK for some scenarios. At the same time this means that new users, that have the same VMID, will have access to other users data. Is there any way to sync deletion on PVE with PBS...

    How can I shrink a ZFS / RAW disk?

    Hey, I have a 1TB RAW disk (rpool/data/vm-101-disk-0) on a ZFS pool (local-zfs) that I want to shrink to 256 GB. The VM uses cloud-init. The real usage is about 15 GB, so there's plenty of space to shrink. I've tried to do a zfs set volsize=256G rpool/data/vm-101-disk-0 which works, but the...

    Backup crashes VM - 'guest-fsfreeze-freeze' failed - got timeout

    Nope. We disabled Qemu on the Guest VMs and we're making backups without that. Yes, the backups can be corrupted (as it doesn't freeze the OS), but it's better than nothing.
