    Ceph network setup for Wan rbd replication

    AFAIK RBD mirroring needs access to the public networks of both Ceph clusters.

    Cephx Key Migration Procedure and Ceph 19.2 Squid Going EOL Soon

    No, as the kernel is too old. BTW: i would not recommend mounting CephFS directly on workstations where users have physical access. It is too easy for them to impersonate another user. Use SMB in such a scenario.

    Ceph OSDs not being able to be configured in fully routed Environment

    Is 192.168.99.1/32, 192.168.99.2/32, 192.168.99.3/32" the content of your public_network setting? You should change that to maybe 192.168.99.0/24.

    (SOLVED) CEHPX Disabled, CEPH Key Migration - Removing an auth entry?

    What does "ceph auth ls" show? Do not post the output here but look for the mentioned keys. If not needed any more they can be deleted.

    How are people handling ceph v19 osd fragmentation?

    One recommendation is to increase the number of placement groups for pools with many objects. This reduces the size of each PG and makes it easier to place them on OSDs avoiding fragmentation.

    PVE+ISCSI

    It still works with current kernels as the io_uring bug has been fixed. According to https://www.kernel.org/doc/html/latest/process/maintainers.html OCFS2 is actively maintained.

    Purpose of pve-dbus-vmstate@VMID.service?

    It looks like the timeout messes things up.

    Purpose of pve-dbus-vmstate@VMID.service?

    Hi, what is the purpose of the pve-dbus-vmstate@.service? It starts a Perl script /usr/libexec/qemu-server/dbus-vmstate but not for every VM. We have seen it running for a few VMs and sometimes it fails: Aug 31 15:17:22 pve56 systemd[1]: Starting pve-dbus-vmstate@6000.service - PVE DBus...

    Proxmox VE 7 is vulnerable to some type of 0day/RCE non auth

    Sorry for your loss, but why would anyone do that?

    Proxmox + Ceph across 2 datacenters

    Basically you need three locations for automatic HA. Otherwise you will always have issues with split brain situations. Addendum: If there is no common layer 2 network available for the VM traffic you cannot migrate a VM from one location to the other.

    Migration from VMware vSAN to Proxmox CEPH

    This will only work if the current VM workload only needs less than half of the available hardware resources.

    Grundsatz für Shared Storage

    Ich wüsste nicht, was an der Verwaltung von /etc/exports komplex sein sollte.

    Grundsatz für Shared Storage

    apt install nfs-kernel-server installiert einen NFS-Server im Proxmox, denn das ist auch nur ein Debian. Zur Einrichtung und Verwendung eines NFS-Servers empfehle ich weitere Recherche im Internet.

    Grundsatz für Shared Storage

    In einem solchen Szenario wäre ein NFS-Server direkt auf dem Proxmox die simpelste Lösung. Und dann die NFS-Exporte nach Bedarf in die VMs mounten.
