    Hilfe nach SAS Controller Tausch - ZFS Pool ist nicht mehr da

    ...genauer an: fdisk -l /dev/sdb fdisk -l /dev/sdc Siehst du noch Partitionen, oder sind die Platten "raw"? zdb -l /dev/sdb zdb -l /dev/sdc Wenn ZFS-Metadaten noch vorhanden sind, siehst du hier den Pool-Namen und die GUID. ZFS schreibt seine Labels an den Anfang und ans Ende jeder Disk...

    Hilfe nach SAS Controller Tausch - ZFS Pool ist nicht mehr da

    ...Einstellungen. Da der HBA Modus war nicht eingeschaltet und wurde von mir aktiviert. Blauäugig wie ich bin, ist auch meiner erster Kontakt mit ZFS, habe ich natürlich keine Maßnahmen ergriffen, wie ein Pool export oder gar Backup. Nach dem Boot mit dem getauschten Controller meckerte Proxmox...

    Does forcing 4Kn on VM disks actually help?

    ...the same for 512 and 4kn throughout multiple runs with difference about 1% - which might be statistical error. Other tests - random read, sequential read/write, fsync showed even smaller differences. I might test that on different PVE cluster using ZFS next time. Thanks everybody for your...

    Does forcing 4Kn on VM disks actually help?

    Running PVE on hosts with 512/512 disks, storage is ZFS (ashift=12) and Ceph. Guests use virtio-scsi-single, mostly Linux, some Windows. I wonder if it's worth adding (or similiar): args: -global scsi-hd.physical_block_size=4096 -global scsi-hd.logical_block_size=4096 For Linux it feels...

    Proxmox(zfs) > lxc > docker container > OOM results in "kernel BUG at mm/usercopy.c:102!"

    Thanks for looking through openzfs issues - seems like this could indeed be a fix - I'll try to reproduce the issue here. * Does your System have `/` on ZFS? * how does the container config look like? (`pct config <vmid>`)? * how does the zpool look (`zpool status`) * could you share the...

    TrueNAS Storage Plugin

    Having looked at your code a bit I think your plugin manages iSCSI at a lower level than the native ZFS over iSCSI implementation. Proxmox relies on iscsidirect to make the connections.

    Plan to build a NAS and want to use Proxmox advice

    ...here today and realized I never replied! I ended up building my NAS and pretty much took most of the advice you wrote above. I installed Proxmox on two 1TB M.2. running in a ZFS mirror. I then passed through an HBA card to TrueNAS and running three 3.5" drives in RAIDZ1. Thank you for your...

    Migrating PVE install from flash to NVMe

    Another option would be to copy /etc/pve from a zfs or lvm snapshot.

    [SOLVED] Proxmox Backup Server boot to BIOS after upgrade from 3 to 4

    That’s why a little bit of context helps a lot because seeing that error I focused on the zfs itself :-)

    [SOLVED] Proxmox Backup Server boot to BIOS after upgrade from 3 to 4

    Try booting the virtual with a different options or kind of livecd to try the zpool import -f rpool This will show you the reason why it didn't import automatically. It could be because the drive is inaccessible or zfs pool is in some unexpected state.

    [SOLVED] Proxmox Backup Server boot to BIOS after upgrade from 3 to 4

    Hi, It looks like ZFS pool didn't import properly after the upgrade. It's not pbs/proxmox specific - Linux usually doesn't like bios->uefi upgrades. Can you boot the vm into shell and try importing the zfs pool manually ? zpool import -f rpool

    GPU Pass-through working kinda

    Try to set Display to none. Maybe configure a serial terminal first. Unrelated but you should enable discard for disks on a thin provisioned storage such as local-zfs.

    Caching drive replacement

    Also just realized, I believe the original disk was in a zfs by itself. The caching was then pointed at the zfs pool I believe.

    zfs over iscsi migration path?

    I have a PVE 8.x cluster using TheGrandZazoo's freenas‑proxmox plugin to work with data served from TrueNAS Scale 23.10.2. I'd like to get PVE and TrueNAS upgraded to the latest versions, and start using the new truenas-proxmox plugin. I've not had any luck finding a guide for migrating from the...
