  1. options zfs zfs_arc_max still needed for stability now-a-days?

    It crashed again after two months. So i decided and limited max_arc to 2 GB (from 4 GB as was default). Will see..
  2. options zfs zfs_arc_max still needed for stability now-a-days?

    Hi @LnxBil , thank you for your reply and sorry for my late response (life happenz). To answer further, we already use KSM. I guess the solution here would be to restrict max ZFS ARC < ( SUM(VM RAM) + 2GB for PM host).
  3. KVM console black until I switch to ttyXY with ctrl+alt+fXY

    Hi, after conversion of LXC to KVM which works, i have black screen / VNC console until I switch to tty1 with ctrl+alt+f1. Any ideas how to fix this, so that KVM 16.04 ubuntu based will start at tty1? I also just noticed, that when I use console for text input, it does not work. Picture shows...
  4. options zfs zfs_arc_max still needed for stability now-a-days?

    Sorry for the late reply and thank you for the answer. Below linked is current arc_summary. Not from the time of the crash, however, hypervisor has not been rebooted since VM was killed. If you want some other data, let me know. Have had to link, post character limit was reached...
  5. options zfs zfs_arc_max still needed for stability now-a-days?

    Hi, I just hit OOM killer today, due to ARC not retreating fast enough, so I guess it is still a problem nowdays. I have had SWAP on the same host and was almost empty when OOM killer hit. (I use MDADM SW RAID for it, cause ZFS has problems holding SWAP.) It;s sunday today, so I will continue...
  6. options zfs zfs_arc_max still needed for stability now-a-days?

    I have had no OOM kills till now, even when I let ARC grow and it has to shrink due to memory pressure from VMs. Still cautious about doing it on all the servers.
  7. Create a cluster on a node which has VMs

    Hi guys, I understand and always join an empty node to the cluster. But now I want to create cluster from one server which already contains VMs and is in production. Can the first node, the one you create cluster on, also contain VMs? If not, then I have to install new node, create a cluster...
  8. PBS 2 on PM 6

    Hi guys, does PM 6 work with PBS 2? I wonder if I should upgrade PBS from 1.1 to 2.*. It is used bt PM 6 cluster, fully updated. Have no plans for upgrade PM 6 to 7 a.t.m.
  9. PM upgrade from 6 to 7 chrony or systemd-timesyncd

    I guess I will have to fix the script so that it does not check all services. Till now if a service was listed in PVE, it was supposed to be running. But not anymore, so I guess this has to be changed: " def services return unless @options[:mode] == 'services' http_connect(path...
  10. PM upgrade from 6 to 7 chrony or systemd-timesyncd

  11. PM upgrade from 6 to 7 chrony or systemd-timesyncd

    Any1? @dietmar @tom @dcsapak @fabian @wolfgang @Stoiko Ivanov
  13. PM upgrade from 6 to 7 chrony or systemd-timesyncd

    I monitor all services listed in PVE HTTP GUI under System: After upgrade from 6 to 7 i got notifications about chrony not running. I installed chrony (replaced systemd-timesyncd) but now systemd-timesyncd failure is triggering monitoring system. As both can not run at the same time, I wonder...
  14. [SOLVED] What exactly does "apply network configuration"?

    Hi, since we have installed ifupdown2 we can apply network configuration without restarting the host. What would the manual equivalent of this apply button be in shell? I tried ifdown vmbr0 && ifup vmbr0 and all VMs instances network cards were removed from the bridge and lost connectivity.

  17. No space left while moving disk

    Wish @mira would answer. :-/
  18. No space left while moving disk

    @mira thank you for your suggestion. Please let me know if I understand it correctly. You suggest to resize both volumes (x 1.7 and x 2.4) and then move the volumes from ZFS to ext4? You say, newly created raw disk on ext4, which should have the exact size as the previous zvol (530 GB), is not...
