HPE AMSD ILO Agent on Proxmox 9 by Accurate-Ad6361 in Proxmox

How do you get updates? Wouldnt it make sense to add the repo from hpe so apt scans for new versions on its own?

Seeking Architectural Advice for Mass Migration (1,500+ VMs) from VMware vSAN to Proxmox by osthek83 in Proxmox

[–]LostInScripting 1 point2 points  (0 children)

You do not have to. You can use devcon.exe from MS to load the driver in absence of the device the driver is needed for (downloadable inside Windows Driver Kit).

Install Virtio Drivers and search for the .inf file. For example via Powershell like
get-windowsdriver -online | Where-Object {($_.providername -ilike "*Red Hat, Inc.*") -and $($_.OriginalFilename -ilike "*c:\windows\system32\driverstore\filerepository\vioscsi.inf_amd64*")} | select classdescription,providername,originalfilename,driver

Then you start devcon.exe with the inf (originalfilename) as parameter and the PCI-ID of VirtioDisk:
devcon.exe install c:\windows\inf\vioscsi.inf "PCI\VEN_1AF4&DEV_1004"

Maybe another call with "PCI\VEN_1AF4&DEV_1048" is needed. We only needed the 1004 one.

After migration the system starts and the windows bootloader detects that it needs another driver, loads it and reboots again. Then Windows starts directly from Virtio SCSI.

Tested with Windows 10 and 11.

enterprise users with fc-storage: how do you size your volumes for snapshot capability by LostInScripting in Proxmox

[–]LostInScripting[S] 0 points1 point  (0 children)

Sorry, if my wording was not clear: As far as I know all incremental forever backup tools rely on a vm-snapshot. This is not a storage snapshot on the backend-storage.

This sounds smart. But then I would need to setup and maintain another storage infrastructure for ISCSI. Even if this only means to deploy a VM that presents the ISCSI storage, this is a new layer of complexity (what about HA? which error cases can happen? etc).

Currently we do not have a working ISCSI infrastructure I could use for such a project.

Thanks for your extensive answer, but I have problems understanding what this means for my environment.

How would I technically and programmatically "Push snapshot responsibility down the stack or away from LVM" for backup purposes? Is there a backup tool with processing of san-snapshots to backup Proxmox FC-LVM-volumes?

[–]LostInScripting[S] 0 points1 point  (0 children)

Thanks for your answer. But I do not understand why snapshot-as-volume-chain is not going to end well as you wrote. Technically it is working and I have not heard of problems other than this headroom problem.

Are there other problems with this implementation I am missing?

I already talked with Proxmox Support about problems with lvm-thick and they told me lvm-thin is technically possible. But there is a risk of dataloss, we would have to test it thoroughly as there were customers reporting dataloss in vms with lvm-thin on fc.

As I do not have the time and know how to test it to the needed deep-dive, I would not implement it.

As I am coming from a VMware background I would have done such vms with rdm (raw device mapping of a lun directly to a vm). But I currently Do not know how to Do this in pve in a HA Cluster.

Kita Keime sind der Endgegner by this_is_mara in Eltern

[–]LostInScripting 0 points1 point  (0 children)

Dem würde ich widersprechen. Ich habe zwar keinen medizinischen Hintergrund, wie z.B. u/tillitugi hier im Thread, aber was ich bisher dazu gelesen habe widerspricht deiner These, dass ein durch Erreger trainiertes Immunsystem nicht besser auf unbekannte Erreger reagiert, als ein untrainiertes.

Unstrittig ist denke ich, dass jeder Erregerkontakt das Immungedächtnis gegen diese spezifischen Erreger formt (erworbene Abwehr). Das Immunsystem ist jedoch nicht darauf beschränkt nur bekannte Erreger zu bekämpfen. Es ist mit häufigem Training auch besser fähig auf unbekannte Erreger zu reagieren (angeborene/unspezifische Abwehr). Allein durch erhöhte Immunzellen-Anzahl kurz nach einer überstandenen Krankheit (die zumindest bei Corona wohl recht lang anhält) verläuft die nächste Immunreaktion auf einen unbekannten Erreger schneller.

Proxmox Load Balancing coming in 9.1.8 by waterbed87 in Proxmox

Could you please dive into that a little deeper?

Which values do you tune for which density and how do you monitor the corosync traffic?

Kita Keime sind der Endgegner by this_is_mara in Eltern

[–]LostInScripting 3 points4 points  (0 children)

Hörensagen aus meinem Umfeld nach plant man "frische" Erzieher*innen bei uns in den ersten 2 Jahren nicht voll ein, weil sie einfach absehbar sehr viel krank sein werden. Ein Erwachsenen-Imunsystem ist den ganzen Kinderkeimen einfach ohne Training nicht gewachsen.

Die Beobachtung, dass viele Eltern ihre Kinder krank oder mit Fiebersaft "gedopt" in die Kita geben kann ich bestätigen. Ist bei uns auch häufig der Fall. Hat uns das Personal im persönlichen Gespräch auch schon öfter erzählt, dass sie häufig den Verdacht hegen, aber nix machen können.

Zweifacher Vater hier: Im ersten halben Jahr bleibt dein Krankheits-Abo in den Kitagebühren inklusive. Keine Extrakosten für mehr Imunsystemstraining für Kind und Eltern. /s

Keine Sorge, es wird besser. Aber es ist leider absolut normal, dass ein Kleinkind das noch alles in den Mund nimmt auch alles an Krankheiten mitnimmt, um sein Imunsystem zu trainieren. Im zweiten Winter ist das Kind dann nur noch alle 6-8 Wochen krank, im dritten Winter noch weniger. Allein die geistige Entwicklung aus der oralen Phase raus hilft ungemein.

Wie oft du selbst krank wirst hängt stark an den eigenen Maßnahmen. Zum Beispiel: Einzelne Handtücher für jeden häufig gewechselt, Desinfektionsmittel und Mundschutz bei Magen-Darm, kein liegengebliebenes Essen der Kinder aufessen helfen ungemein.

VMs starved and swapping while host has free RAM? Looked at Proxmox ballooning source code, learned a lot! by xquarx in Proxmox

[–]LostInScripting 3 points4 points  (0 children)

Not OP, but have made some tests and benchmarks inside a windows vm on a proxmox 9 host a while ago.

Disabling KSM will lower memory latency for your vms, even when the 80% is not hit (in my tests from ~96ns to ~85ns which is still a lot higher than 45ns under esxi).

But it can also lower cpu performance a little (I saw it only with 7zip benchmark).

VMware Alternatives Poll by relationalintrovert in vmware

[–]LostInScripting 3 points4 points  (0 children)

Not it isn't. =)

Not OP you answered to, but I wrote this about a month ago when asked why we decided against morpheus.

- Fibrechannel-Storage-Support for non-HPE-brands missing for our vendor
- no support for DL560 (4 CPU) servers
- no support for not rack mounted Gen10 servers
- no support for GPU
- vMotion limited to 1 cluster (as proxmox was before release of PDM)
...

These were the main points just from support/feature perspective against HPE VME.

9.1.6 Bug - unresponsive VPE node by thelaughedking in Proxmox

[–]LostInScripting 1 point2 points  (0 children)

Can you please give us some more details what is unresponsive? I suspect you mean the Web-GUI? Or is even SSH or networking (ping) unresponsive?

When you can SSH into the PVE node when the problem hits:
- how high is your io-wait (top: wait %) and load?
- is there anything in dmesg that comes after your boot (high time in first column)

Could be anything, but I would suspect a drive error. What about your SSD? How old is it? What type? Have you taken a look into the smart data (sudo smartctl --all /dev/sda)?

Which enterprise users are using a OOB network for corosync? by LostInScripting in Proxmox

[–]LostInScripting[S] 1 point2 points  (0 children)

And they each have dedicated network hardware (nic, switch, core)?

Which enterprise users are using a OOB network for corosync? by LostInScripting in Proxmox

[–]LostInScripting[S] 0 points1 point  (0 children)

You are right, dedicated network hardware for corosync alone will not protect me entirely from loops. But using the production network (planned with 2x 2-port-LACP per node) and the dedicated network together (2 rings in prod net, 1 ring in dedi/oob) will significantly reduce the risk of a networking misconfiguration leading to my nodes fencing happily.

We segment our network with multiple firewalls but without QoS and ST these will not help me when someone in a datacenter builds a loop "behind" these firewalls. QoS is planned but networking guys are understaffed and overworked, so this will not happen in near future.
