UdoB replied to the thread Request for help regarding random crashes.You should have installed version 9, not 8.x then! Try to find hints regarding the crashes in the Journal. If it happened during the previous boot you can look at the end of the relevant journal like this: journalctl -b -1 -p warning -e For...

UdoB reacted to eroji's post in the thread PVE 8 to 9 upgrade issues, need help with recovery with
Like.
Ok I was able to figure out the issue. The thunderbolt interface.d configuration was the culprit. The old config did not seem to want to work with 9. Checking the page I got the instructions from... -
of=/dev/zero ?? better be /dev/null otherwise get the sunglasses :cool: Interesting random as fast as urandom ... what I saw too on newer cpus you can do same as fast as having cores which was previously only one max and with more processes only...

UdoB replied to the thread zfs send over 10Gbe horribly slow.Yes. Maybe. No. On the same machine as above: ~# dd if=/dev/random of=/dev/null bs=1M count=5000 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB, 4.9 GiB) copied, 8.26672 s, 634 MB/s ~# dd if=/dev/urandom of=/dev/null bs=1M...

UdoB replied to the thread zfs send over 10Gbe horribly slow.Yes, that's burned into my own mind too. But "something" has changed. I can read 5 GB from both devices with the same speed: ~# dd if=/dev/urandom of=/dev/zero bs=1M count=5000 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB, 4.9...

UdoB replied to the thread [TUTORIAL] FabU: can I use Ceph in a _very_ small cluster?.Yes, that's the idea behind "min_size=2" :-)

Ok, Asche auf mein Haupt. Man sollte halt auch die Guest Tools im GAST-SYSTEM d.h. der VM installieren! Dann funktioniert es. :) Ich hab es so (miss)verstanden, dass die Guest Tools die Verbindung zum Gast-System herstellen und somit auf dem PC...

There is no "migration" with only three nodes. the "3" in your crush rule refers to how many copies on individual nodes that have to exist in order to have a healthy pg (placement group.) the number of OSDs dont matter in this context- you can...

UdoB replied to the thread [TUTORIAL] FabU: can I use Ceph in a _very_ small cluster?.Well, my whole point in the first post is that the absolute minimum is not a scenario I would like to use. If you think it will work fine for your use case: go for it! (No sarcasm, I mean it!)

The main purpose of 3rd node is just to avoid split-brain situation and halt everything. VMs could/should hop between the stronger node1 and 2 in case of a failure, the third node therefore ensures the avoidance of split-brain with quorum. If...
-
I have plenty systems I can use for quorum but indeed as you and @UdoB have said I will go trough our inventory here and try to create a 3rd actual server which will take over some VM's if 1 of the main 2 end up dying. If i'm not wrong I do have...
-
UdoB replied to the thread 2 node cluster setup advice.That decision is completely up to you :-) You seem to have some other equipment. I would check if a small VM or a container could be placed there - to implement the Quorum Device. On the other hand a physical third server, even if small and...

We do not rely on npm for our user interfaces; the current Proxmox VE web interface uses only ExtJS and our own libraries. Some of the projects we reuse use npm themselves though, such as xterm.js and noVNC, but we also vendor these completely...

I doubt this since afik ProxmoxVE doesn't use any npm packages and no security advisory on that attack is eported in the related forum section: https://forum.proxmox.com/forums/security-advisories.26/ The latest advisoryies cover some issue...

Durch exkrementelle Backups sparst du halt sehr viel an Speicherplatz und ggf. an Traffic. Die die Inkrementellen Backups über PBS kann man auch verifizieren. Den USB Festplatten würde ich wohl weniger vertrauen. ;) Du könntest ja weiterhin in...

Maybe it's not the right trace (as you stated the error is random), but... I'd start with verification of the backups. https://pbs.proxmox.com/docs/maintenance.html#verification ... Aside from using verify jobs, you can also run verification...

Hi Du kannst "chronyc sources -v" nutzen um eine Liste der aktuellen Zeitquellen anzuzeigen und um zu prüfen, ob die aktuelle Konfiguration valide ist. Falls Ceph eingesetzt werden soll, sollte das definitiv vorab passieren. root@pve:~# chronyc...

Use a hostname in your storage config and put the different IP address in the hosts file of each server?
