UdoB replied to the thread 3 Knoten Cluster + Ceph / Empfehlung für Aufteilung der SSDs.Du hast gute Technik für ein Labor. :-) Für einen produktiven Cluster sind aus meiner Sicht aber drei Knoten zu wenig. Sobald irgendwo ein Problem auftritt, ist das ganze "degraded" - und bleibt es auch dauerhaft, zumindest wenn man die... -
UdoB reacted to pregrcl's post in the thread Recommendation for Virtual Machine Storage (HW-Raid1 or not) with
Like.
For the moment i configured it like this: HW-Raid-Controller set to JBOD to pass through the disks ZFS Raid 1 on the two disks via proxmox Storage on this ZFS Raid VMs use this storage Hope this makes sense, at least this way i have snapshots... -
UdoB reacted to news's post in the thread Using PBS namespaces with an older version of Proxmox VE (PVE) with Like.
So this is you choice of doing so. Go and update your environment, as soon as you can.

UdoB replied to the thread Externer Logserver.Ich verwende kein PMG... ...aber die Basis bildet Debian. Ich verwende: https://manpages.debian.org/trixie/systemd-journal-remote/systemd-journal-upload.8.en.html (Rsyslog ist ja leider deprecated und passt nicht mehr gut zu systemd.)

Hi, Windows has: pagefile, hibernation, updates, disks defragmentation, copilot and antivirus activities (if you have it) etc. If add the software plus some DBs (if used) and you have solid amount of the changed data inside the VM. Check all...

UdoB replied to the thread Upgrade 9.0.6 auf 9.1.1.Nun, in deinem Schnippsel sind nur die Debian-Sources aufgeführt. Es fehlen die Proxmox spezifischen Elemente. Schau hier: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_no_subscription_repo...

UdoB reacted to nvanaert's post in the thread Dell PowerEdge direct NVME v.s. PERC H9xx Hardware RAID with Like.
Per my testing on several environments previously I found that using ZFS is actually faster (in most cases), due to the fact that the hardware RAID controller only exposes x2 (as it supports 8 drives and 8x x2 is 16; a full PCI-E slot. I also...

UdoB replied to the thread Dell PowerEdge direct NVME v.s. PERC H9xx Hardware RAID.ZFS works hard to assure integrity of the data it handles. This usually requires several actual writes per single write command. (Possible "write amplification" plus handling metadata, depending on the pool architecture.) A stupid Raid...

UdoB replied to the thread Replacing all drives on clustered nodes.What I would do in beforehand is to setup a virtual cluster with similar topology (but much smaller) devices. Then one can simulate/train such a delicate operation. The bad news: to create such a thing may be a complex task in itself. But either...

UdoB replied to the thread Can I install molly-guard on a pve node?.A node running HA-relevant resources fences itself, if Quorum ist lost. The reboot is "hard", triggered locally. Not by an ssh-command from another node ;-)
-
UdoB replied to the thread Can I install molly-guard on a pve node?.Yes. That's what it is meant to do :-) Correct. I do not use that method often, so it is not relevant to me :-) You cat set: root@pve:~# grep ALWAYS /etc/molly-guard/rc # ALWAYS_QUERY_HOSTNAME ALWAYS_QUERY_HOSTNAME=true Then it will ask for...

Hello, You can do it but I recommend you to not stay for a long time in this configuration. Limit modification in your cluster until you have completed your migration. Avoid migration from a node with PVE9 to PVE8 nodes and always use web...

UdoB replied to the thread [PROXMOX CLUSTER] Shared disk for VM.Yes, Ceph is great! Just be aware that there may be pitfalls you should know before starting that journey: https://forum.proxmox.com/threads/fabu-can-i-use-ceph-in-a-_very_-small-cluster.159671/

Adding to onslow: qcow2 is a format for vm discs images on file-based storages like directory, nfs, cifs etc. Since this format is restricted to vm images you can achieve snapshots of vms stored on nfs with them but not on lxcs. You could still...

I FIXED IT!!! I had to stop the new node from trying to cluster with systemctl stop pve-cluster then /usr/bin/pmxcfs -l, after this I was able to create the nodes directory and pscp the files from my Windows machine to the new server. After that...

UdoB replied to the thread Help recreating deleted VMs and LXCs.It was a cluster, right? Did you do that on all nodes? If not: start one of the other nodes and use "pmxcfs" local mount to access /etc/pve/nodes/abc/xyz. Remember: cluster configuration is shared between all nodes --> it is/was available on all...
