    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...

    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...

    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!)

    UdoB reacted to mr44er's post in the thread 2 node cluster setup advice with Like Like.
    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...

    UdoB reacted to SeppeM's post in the thread 2 node cluster setup advice with Like Like.
    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...

    UdoB reacted to t.lamprecht's post in the thread Proxmox VE - Support Lifecycle with Like Like.
    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...

    UdoB reacted to Johannes S's post in the thread Proxmox VE - Support Lifecycle with Like Like.
    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...

    UdoB reacted to DeuSimon's post in the thread dump vs pbs with Like Like.
    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...

    UdoB reacted to Onslow's post in the thread VM restore from PBS fails with Like Like.
    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...

    UdoB reacted to bl1mp's post in the thread Chrony NTP Server ändern with Like Like.
    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?

    Happy birthday to this 5 year old tread today :cool:

    UdoB replied to the thread CEPH Experimental POC - Non-Prod.
    I am not a storage guru, sorry. But yeah, NFS is simple, old+stable and shared. A "simple" setup will create a SPOF though! For PVE I am utilizing ZFS with replication. It gives me the performance of local drives, does not introduce networking...

    UdoB reacted to arankaspar1's post in the thread CEPH Experimental POC - Non-Prod with Like Like.
    I did read that a few times - you sent it to me before haha. That's a nice write up and easy read. I'm just trying to get shared storage. An iSCSI or NFS share would be amazing. Could you serve a share using those and mount it in Datacenter...

    "Muss" nicht, aber plausibler Weise: ja. man chrony.conf beschreibt die Details.

    Ah! We will start upgrading the other servers shortly.
  • UdoB
    This has been discussed dozens of times already. That setup with those backup sizes won't ever perform well. You are using the two things that kill PBS GC performance: network shares and HDD only datastore. Your datastore size requires proper...
