  1. Windows Server 2016 frequent lockups with 100% CPU

    Hi Oxib, yes I've been able to resolve via Proxmox support. Basically I installed a package (vlan) via APT which removed the package "proxmox-ve" and prevented pve kernels to be updated. After I reinstalled the "proxmox-ve" package, did a apt dist-upgrade and reboot, everything started working...
  2. Windows Server 2016 frequent lockups with 100% CPU

    No luck. :( VMs still experience lockups and I had to create a script that runs every 5 minutes, pings the guest agent and powercycles the vm when it doesn't reply. It's not the best solution, I know, but at least this reduces the downtime.
  3. Windows Server 2016 frequent lockups with 100% CPU

    Digging into the forum I discovered a few posts which could be related to some APIC issues. https://forum.proxmox.com/threads/windows-2003-64-bit-random-crashes-apic-related.5317/ https://forum.proxmox.com/threads/windows-xp-multicore-bsod.4550/ which both resolved by disabling some power...
  4. Windows Server 2016 frequent lockups with 100% CPU

    Don't know if this could help, but I found some errors in the eventlog: Bugcheck 0x00000109 with 0x17 as the 4th parameter means Local APIC modifications (from https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x109---critical-structure-corruption) Memory.dmp is...
  5. Windows Server 2016 frequent lockups with 100% CPU

    Looks like the system behaves better, but lockups still happen even if less frequently. I really don't know what to do next. Please help! EDIT: I exclude any hardware defect because only windows server 2016 vms are affected the idrac on the server does not report any issue
  6. Windows Server 2016 frequent lockups with 100% CPU

    As of today the issue is still present and happens really often. Just updated BIOS and storage controller's firmware to latest version from manufacturer. Let's see how it goes.
  7. Windows Server 2016 frequent lockups with 100% CPU

    Hello, since a few days we're experiencing frequent lockups on ALL Windows Server 2016 VMs (i got 3). These vms have been running without any issue for months, but now all are experiencing the same issue. As you can see from the attached screenshot CPU spikes at 100% and there's no way to...
  8. Proxmox backup behaviour

    Thanks for the clarification.
  9. Proxmox backup behaviour

    Hello, I have the following scenario: a backup task of 5 vms is running at 09:00 pm and, for simplicity, let's assume that each backup is 10 Gb. The backup storage is set to maintain 5 copies, and at the current time there are already 5 copies, so at the next backup the oldest should be deleted...

    Hi Fabian, no, I didn't manually force quorum in any way.
  12. Help! Dangerous behaviour on 3-nodes PVE HA cluster

    Hi, I have the following configuration on my DELL VRTX: 3x M630 blades attached through a DAS with a Shared PERC8 raid controller in multipath failover configuration (as described in DELL documentation). /etc/multipath.conf defaults { verbosity 2 polling_interval 10 uid_attribute...
  13. Help! Dangerous behaviour on 3-nodes PVE HA cluster

    Hi, thanks for your reply. I can tell for sure that nobody had directly modified that file... and neither had I, of course. Anyway, when I was installing the server, I restored that vm from backup on the SAS storage and then moved the 50GB disk to SSD storage through UI -> Move disk .. no...
  14. Help! Dangerous behaviour on 3-nodes PVE HA cluster

    Hello everybody, At the beginning of this week, I just deployed a new PVE 4.4-13 cluster over a DELL VRTX with 3 blades with HA active for almost every VMs, and everything was working flawlessly. Storage is LVM, of course. Just one hour ago, for some unknown reason, one (or more? I didn't get...
  15. Ceph hardware

    So it seems that the overall Ceph performance is not that great as one may think... I mean: can I compare eg. 3-node ceph cluster with 2 osd (15k SAS 600gb) + 1 jornaling ssd per each node against a dedicated FC/iSCSI SAN with the same amount and kind of disks? I think the SAN would win here in...
