    Proxmox HA increase fence delay

    Yes. This was the trick. In order to increase $fence_delay value you must be modify the file /usr/share/perl5/PVE/HA/NodeStatus.pm on all cluster nodes, because every node could play the master role in a cluster at a certain moment and trigger the fencing process. Now, working test is: 1)...

    Proxmox HA increase fence delay

    For the sake of simplicity, I have described only 3 nodes in the cluster, that are participating in the test. In fact, there is a 4 node cluster, and node4 is Master at this moment! I guess I should hack/increase the $fence_delay in /usr/share/perl5/PVE/HA/NodeStatus.pm in node4 also, because...

    Proxmox HA increase fence delay

    My pve-ha-manager version 1.0-40, Proxmox 4.4 Thank you for the tips on graceful reboot, but is not my use case. The default behaviour on graceful reboot is freezing the VMs, and works as expected, even in case of long reboots. In my situation, systemctl stop pve-ha-lrm is not usable, because...

    Proxmox btrfs support roadmap, as fallback for possible licensing issues ZFS on linux

    Why expressly linking btrfs to zfs, and not other filesystem? Let me explain myself. PERFORMANCE VERSUS HA Always, there’s a trade-off between performance and high availability. With ceph distributed storage you have HA, but there’s performance penalty, induced by network latency. With...

    Unprivileged containers

    From my tests, the error tar: ./var/spool/postfix/dev/urandom: Cannot mknod: Operation not permitted, shows when trying to restore an unprivileged container from a backup of privileged container. The cause is privileged container missing mount | grep udev ? This is very strange, because the...

    Deleting data in lxc lvm thin doesn't release space

    Thank you for reply. The only thing working, from your suggestions, is fstrim inside container. I think of running like https://forum.proxmox.com/threads/proxmox-execute-command.26030/, from outside, for my clients, on cron. However, this is the most performant solution, according also to...

    pve-zsync with bind mounts fails

    I read that "Recursive sync" is a feature not so easy to realize. On the other hand, about this bug/feature... How complicated is it? Do you have an ETA to fix it, depending on other proxmox development priorities? Thank you!

    Can't update centos7 (or install httpd) in unprivileged LXC container.

    Practically, you have done '' Is it a reasonable workaround to set the container to privileged, install httpd, and then set it back again?

    Can't update centos7 (or install httpd) in unprivileged LXC container.

    Quote from stgraber "Until the kernel supports unprivileged fs capabilities you need security.privileged set to true which should then fix your problem, at the cost of much degraded container security." https://github.com/lxc/lxd/issues/1245#issuecomment-233199884
