    [SOLVED] Inconsistency Grub Menu vs. /boot/grub/grub.cfg

    Hello! I have a question regarding the content of Grub Menu vs. /boot/grub/grub.cfg. In my case the content is inconsistent. And this is causing an issue with booting a BTRFS snapshot, because the required snapshot won't boot with the options displayed in Grub Menu. I'm running these software...

    Feature Request: improved snapshot

    Hi, Proxmox doesn't permit to take a snapshot when your VM has a passthru device attached, which sounds rational since snapshots by definition "freeze" (save) the whole state of the VM and that's impossible for non-emulated hardware. BUT there are some scenarios where I think it's still useful...

    The Hassle (and Joy) of Snapshots in a ZFS Cluster

    I’m running a fairly active but small budget Proxmox cluster for circa one year now. Meaning depending on the current project workload it only consists of 3-4 nodes and uses ZFS due to its replication capabilities which allow nearly HA-like failover times (5 to 10 minutes in my case) with a...

    Unterstanding how snapshots under LVM Thin-Volumes work

    Hello, I work with Proxmox 5.2 and LVM Thin-Volumes. I create a couple of snapshots from a windows test-vm and wondering how it worked. A normal thin snapshot under LVM2 used the same size as the original thin-volume has. In my case the thin-lv has 32GiB, so the snapshot would become also...

    adventures with snapshots

    ZFS usedbysnapshot is off by a hundred gigabytes

    Hello, I have a couple of Proxmox 4.4 deployments out in the wild. On occasion, one of them will have their "usedbysnapshot" field grow to incredible sizes. If I do a zfs get all on the vdev, it's showing usedbysnap is 279G. I've listed out all of the snapshots, there are 337 hourly snapshots...

    Ich habe am 29.3. gegen 9:12 Uhr einen Snapshot gelöscht um Platz zu schaffen, dabei gab es einen Fehler, diesen habe ich nicht weiter beachtet, nur gesehen dass in der WebGUI wo ich diesen Löschen wollte, dieser noch vorhanden war. Daraufhin beschloss ich einen Tag später den Host neuzustarten...

    How to mount disk/snapshot read only in other VM (or better approaches)?

    Snapshots on NFS or iSCSI

    Taking suggestions: Samba Previous versions implementation

    Is it possible (or conversely a terrible idea) to expose zfs snapshots to a container? My goal is to enable 'previous versions' via samba's shadow_copy2 vfs object, preferably backed by zfs snapshots, for document storage that can be recovered without IT (me) intervention. The documents in...

    Advice on filesystem for fast snapshot and backup

    Hi there, I need to setup a pair of Proxmox servers. I think I'm not using full HA, because I don't know yet if I'm having shared storage.
