    [SOLVED] Temp and random VM freeze after upgrade to Proxmox 8.2

    Not sure if it's the same issue, but I've encountered a very similar case without KSM. I am trying to remove a swap partition after adding another one. Soon after 'swapoff /dev/oldSwapDev', both pvestatd and most shell commands locked up trying to read '/proc/<some-kvm-PID>/environ', similar to...

    Powerloss Protection (PLP) Mythos

    Die Bandbreite zwischen HBA und DRAM ist grösser und die Latenz tiefer als zwischen HBA und Flash-Speicher. Enterprise NVMe sind daher schneller, weil sie PLP haben, d.H. weil die Daten schon geschrieben sind wenn sie im DRAM ankommen. Consumer NVMes können Daten hingegen erst bestätigen, wenn...

    Powerloss Protection (PLP) Mythos

    In meiner Berufspraxis kommt Datenverlust durch Software-Bugs, Kernel Crashes und HW-Fehler viel öfters vor als Datenverslust durch Stromausfälle. Bei diesen Fehlerklassen kann eine USV den Datenverlust nicht verhindern. Die Erfahrung zegt auch, dass "irgendeine" USVs "hingestellt und dann...

    [TUTORIAL] [Nautilus] activating CEPH DASHBOARD

    TL;DR: Before starting, make sure to apply this workaround on all cluster nodes: adduser ceph www-data mkdir -p /var/lib/ceph/.ceph install -o ceph -g root -m 0640 /etc/pve/ceph.conf /var/lib/ceph/.ceph/ceph.conf I found that ceph-mgr is crashing on all nodes when it tries to reload its...

    Container with custom mountoptions user_xattr

    The documentation doesn't suggest it, but only a few mount options are permitted (LXC/Config.pm): my $valid_mount_option_re = qr/(noatime|lazytime|nodev|nosuid|noexec)/; sub is_valid_mount_option { my ($option) = @_; return $option =~ $valid_mount_option_re; } Though, the config file...

    Backup fleecing: stick to same storage automatically?

    Indeed I was considering the fact that some storage types are not as suitable as others. I was also thinking of not proposing a change which would surprisingly change behavior for other People. That's why I am proposing to introduce both a setting on the storage and on the backup job, both...

    Backup fleecing: stick to same storage automatically?

    Backup fleecing is a good thing. But I'm a bit puzzled by the need to choose a fleecing storage in the backup job: I wonder if I'm the only one missing the option to configure fleecing to stick to the same storage the source is in, whatever that is. I am thinking of having two options: the...

    Ich habe gerade den selber Fehler, und gleiche Voraussetzung: in meinem Server sind Festplatten dazu gekommen, die vorher in einem anderen Server Dienst taten. Die VGs auf beiden Server hiessen gleich (gleicher vg_name "pve", unterschiedliche vg_uuid): root@pbs:/# lvs -o+vg_uuid WARNING: VG...

    [SOLVED] pvecm status fails to parse valid corosync.conf (missing ':' after key '3')

    Now that I walked into it, I have reported it in Bugzilla. I previously ended up reporting it here because I sloppily googled for "how to report bug proxmox", which led to the getting help for Proxmox page, which refers to this forum.

    [SOLVED] pvecm status fails to parse valid corosync.conf (missing ':' after key '3')

    My corosync is working properly. I haven't posted my corosync.conf because I think I see a parser bug that is independent of the config file in /usr/share/perl5/PVE/Corosync.pm (approx line 92). The parser is just a tad too simplistic and fails to parse valid corosync.conf files when they...

    [SOLVED] pvecm status fails to parse valid corosync.conf (missing ':' after key '3')

    # pvecm status missing ':' after key '2' Can't use an undefined value as a HASH reference at /usr/share/perl5/PVE/CLI/pvecm.pm line 486, <DATA> line 960. This is while corosync is happily running, `corosync-cfgtool -n` shows running links etc.. Looks to me like pvecm is choking on the...
