    [SOLVED] Windows freezes when backup / snapshot

    Dear Community, We are using several Proxmox servers and we have some random issues with Windows VMs (Windows 10 & Windows Srv 2019, 2022) when VMs dies during backup and/or taking snapshots. No issues with any Linux VMs or LXCs. It happens on multiple servers but mostly on Intel Xeon E5-26*...

    ZFS Storage Problem - Snapshots

    Hello everybody! I have a problem with my second hard drive in Proxmox. This is not displayed correctly in my opinion. As you can see in the pictures, the free space varies between 300GB and 600GB. On the hard disk there are two VMs which have 1x500GB and 1x64GB + 1x snapshot. Due to my storage...

    VM Snapshots

    Yes, I know snapshots are not backups...:) In VSphere/ESXi, snapshots continue to grow as more and most data is changes since the last snapshot. VMware documentations says to not keep snapshots around for more than 3-5 days. If you go too long, coalescing (merging) the snapshot into the...

    Snapshot - crashes VM by messing up the disks

    Sometime last year I found that when snapshotting a running container with mariadb would cause the database to be unable to complete any queries - the process was running but queries just stacked up. It was as if the fs was missing briefly but could not recover. It was assumed it was a mariadb...

    Can you save a snapshot to a NFS volume?

    I have a NFS mount (10.50.1.220:/volume2/Netbackup1/Cluster_1_Backup/proxmox-24) pointed at /mnt/pve/volume2Snapshots which I would like to save VM snapshots to. I noticed in the WebGUI, when taking snapshots there is no option to select the storage device and the snapshots are saved to whatever...

    How to continue the ZFS incremental storage replication (and avoid a full/base sync) after rolling back a guest

    There is a way to continue PVE-ZFS storage replication as usually after rolling back a guest without having to do a full/base synchronization? I haven't been able and I haven't find nothing on the internet neither. I have tried: to prune dataset snapshots in the hot spare machine to match the...

    Backup timeout for firewall VM

    Hi, Currently I'm running a PVE node on a dedicated host at a host provider. On that host I have a firewall VM to handle all traffic (including traffic of PVE itself). Storage is ZFS based for the PVE server (boot and VM pools) When I perform a backup of the firewall to my remote PBS server I...

    questions about replication and zfs

    Hello, I was hoping to get some clarification about zfs and replication. my VM 104 is running on Proxmox2 in my cluster. I set up a replication task to replicate it to proxmox1 in my cluster. Is the VM on proxmox2 using the snapshot or is it safe to delete the snapshots? (this goes for all...

    Standard pve install. Ubuntu 22.04 LTS. Cannot make snapshot

    I have set up a very standard PVE install on an internal NVMe disk and am running a single 32GB Ubuntu VM in that environment. I understand that I cannot create snapshots for that VM because it has 'raw' format (and resides on storage that cannot snapshot itself). I also understand that if I...

    ansible - snapshot container with mount points

    I've recently opened a PR which adds the functionality to the ansible.community.proxmox_snap module. The module can now be used with a unbind option, which allows to take snapshots of LXC containers regardless of them having configured mount points. This simple task is achieved by "toggling" the...

    Hi Everyone, We've been struggling moving away from a mal-performing CEPH cluster at a customer site for a little while now, however, our NAS supports iSCSI and NFS, but not CEPH or ZFS over iSCSI. Is there truly no solution to include HA, Live Migration, and PBS Live Backups using an iSCSI...
