    [SOLVED] Node in other building keeps showing up as offline to other 2 nodes, possible corosync issues?

    Ping times are way too high for corosync. And do I read that correctly that there is an Internet connection involved? Do you use some kind of VPN between the sites? As can be seen with the round trip times (rtt min/avg/max/mdev = 15.667/25.435/33.892/3.466 ms) there is also much jitter on the...

    [SOLVED] Node in other building keeps showing up as offline to other 2 nodes, possible corosync issues?

    What is the network latency between the nodes on the network used for corosync? is this network on a shared medium? Can there be congestion?

    Ceph OSD crashes on I/O errors under light load with kernel 7.x - ssd via pcie adapter - FIXED with 6.17.13-7-pve

    When even the kernel shows an IO error (in dmesg) it is time to replace the device.

    How to update the web interface after changing hostname from terminal without reboot?

    After changing the hostname a reboot is recommended as other services may also still use the old hostname.

    Das sind schon allein zu wenig Knoten für Ceph.

    Ceph Worker auf RaspberryPi dem VE hinzufügen

    Wie sieht denn der Rest des Clusters.aus? Ich würde davon ausgehen, dass ein Pi zu wenig Leistung für ein OSD hat.

    Proxmox QDevice with a 16 node cluster

    You can assign 2 or more votes to the Qdevice. This could help by providing more votes. E.g.: each PVE node has one vote and the Qdevice has 3. Total votes are 19, majority is 10. 9 PVE hosts can fail and there is still a majority of votes available. But if the Qdevice fails only 6 other PVE...

    OCFS2(unsupported): Frage zu Belegung

    Warum sollte Multipathing den discard-Befehl nicht weitergeben? Bzw sollte das Discard ja die qcow2-Datei im OCFS2 kleiner machen. Auf der Ebene hat das mit Multipathing zum SAN ja noch gar nichts zu tun. Wenn das SAN-Storage selber die LUN thin-provisioned macht, kann ein discard aus der VM...

    Ceph - VM with high IO wait

    By default /etc/ceph/ceph.conf is a symlink to /etc/pve/ceph.conf which makes it the same on each cluster node. AFAIK it is easier to use ceph config set to set the values in the config db for each Proxmox node. ceph config set client.HOSTNAME crush_location az=az1
