UdoB replied to the thread Langsame 4k Performance in Windows 11 VM.Ohne sync=1 ist das ganze asynchron - und "normal" im Sinne, dass nur im üblichen 5-Sekunden-Takt geschrieben wird. Da wird RAM + CPU-Leistung getestet, nicht die NVMe. Aber ja, das ist dann eher "real world" als mit sync=1. -
UdoB reacted to Johannes S's post in the thread Pre-seeding PBS with existing Restic backups to avoid full WAN re-upload on first backup with
Like.
I know otherwise you wouldn't have asked in the first place ;) I just want to know why because imho PBS is best for vm/lxc backzups but not so much for file backups since you need a running PBS for restore. For the stuff on my notebook I want to... -
UdoB replied to the thread network connection.Do you have a specific reason to use this "ancient" release? If not... please upgrade to (non-subscription): ~# pveversion pve-manager/9.1.6/71482d1833ded40a (running kernel: 6.17.13-1-pve)

UdoB reacted to guruevi's post in the thread High VM-EXIT and Host CPU usage on idle with Windows Server 2025 with Like.
@ChrisBozeman I work with plenty of Windows machines - thousands of them - you know what I’m not worried about - 5% CPU usage at idle. This entire thread is for homelabbers worried about their power bill. If I have a 5% power increase after a...

Thanks to Pouch6867 for sharing your script. Until Proxmox introduces a built-in feature for serialized/sequential cluster backups, writing our own scripts is indeed a very practical approach to prevent storage or network congestion. Inspired by...

Das mit den Immutable Backups bei Veeam ist nur notwendig weil das Backup Repository immer erreichbar sein muss. Außerdem ist das nicht wirklich unveränderbar, sondern nur der User mit dem Backups geschrieben werden, darf keine root Rechte haben...

Nicht direkt, aber man kann ( und sollte) die Permissions so setzen, dass von ProxmoxVE nur neue Backups erstellt und bestehende gelesen, aber keine gelöscht werden können. Dazu einen offsite-PBS und man kann ähnliches erreichen: - Per Firewall (...

UdoB reacted to Johannes S's post in the thread [TUTORIAL] FabU: How to setup a Quorum Device and secure it by disabling root access. with Like.
As I said: I agree that it's a good idea to disable root access via ssh to the qdevice. I think it's even better to have a dedicated environment for it, however you set it up ;)

UdoB reacted to Johannes S's post in the thread PBS Verify duration on large HDD-based datastore — how to tune settings? with Like.
For better IOPs consider switching your setup to striped mirrors ( aka RAID10) plus special device

UdoB reacted to news's post in the thread PBS Verify duration on large HDD-based datastore — how to tune settings? with Like.
Its more bad as you think! There is only one NVMe mirror as Special Device, so you can loos everythink, you have no second oder third Dive on your Special Device! Use a Special Device als ZFS Mirror Device with N >= 2 Device.

UdoB replied to the thread Error during installation of PVE.Usually the relevant .iso has been downloaded to (and is stored on) the same PC where I am using the web browser for iDrac on = my local PC. The whole point of this mechanism is that the .iso is not copied to the server ahead of (boot-) time but...

UdoB replied to the thread Error during installation of PVE.It should do so: https://www.dell.com/support/kbdoc/en-us/000124001/using-the-virtual-media-function-on-idrac-6-7-8-and-9#idrac6

UdoB replied to the thread PBS Verify duration on large HDD-based datastore — how to tune settings?.A single vdev? That's worst case - there is no way no make it slower than that! (Even a RaidZ3 has the same IOPS = same speed...) My recommendation would have been 7*mirrors --> seven times the IOPS of that construct... Sorry, I have no trivial...

UdoB reacted to VictorSTS's post in the thread PBS Verify duration on large HDD-based datastore — how to tune settings? with Like.
Find out yourself with your hardware: apt install sysstat Start two terminals: iostat -dx 2 top -H Increase readers until the load on iostat for every disk is ~90% (or some lower limit to leave headroom for other activities on the same zpool)...

UdoB reacted to phip's post in the thread How can I back up my VMs without slowing them down? with Like.
You may want to enable "Backup fleecing", which directs writes during the backup to a local fast image to avoid slowing down guests: https://pve.proxmox.com/wiki/Backup_and_Restore#_backup_modes

UdoB replied to the thread [TUTORIAL] FabU: How to setup a Quorum Device and secure it by disabling root access..Sure. My post says nothing against that approach - disabling ssh for root (originating from the PVE cluster) is okay for a PBS+QDev too :-)

UdoB reacted to Johannes S's post in the thread [TUTORIAL] FabU: How to setup a Quorum Device and secure it by disabling root access. with Like.
While it's surely a good idea to disable ssh login for root I still think that for even better isolation of the qdevice a setup like the one described by @aaron here is to be oreffered...

UdoB reacted to pulipulichen's post in the thread Proxmox host/node failure behavior questions with Like.
Hi Henry, I think the main point of confusion here is that `pvecm nodes` does not necessarily show every configured cluster node. It only shows the currently active membership, so an offline/dead node not appearing there does not mean it was...

UdoB replied to the thread [SOLVED] What are the best practices for using Windows as a Q-Device arbiter in a two-node PVE cluster?.The Quorum Device cannot access the cluster via ssh. The cluster can access the Quorum Device - until you remove the rights granted during installation...

UdoB replied to the thread PBS on desktop pc with SSD or in VM on PVE or not at all?.We did not verify this at that time. I did it now, a few months later: https://forum.proxmox.com/threads/fabu-how-to-setup-a-quorum-device-and-secure-it-by-disabling-root-access.181525/
