  1. After migration of Windows Servers 2019 a reboot is needed

    Always when we migrate Windows Servers they stuck with an error screen. After a reboot they work normal again. Today I migrated some VMs to an other node and back to update the pbs library which is used by the VMs. All 4 VMs needed a restart afterwards. It was a DomainController, 2...
  2. Sync from PBS to PBS failed: too many open files

    On friday I created a sync job to copy files from PBS-02 to PBS-01 PBS-02 has different datastores and PBS-01 uses the 'new' namespace feature. Both PBS are running the latest no-subscription version 2.2.5 Updated 29.07.2022 and both rebootet, On PBS-01 (target) I get...
  3. Some backups are not saved in the namespace

    Hi, I just tried to store the backups in a namespace. Most VMs and CTs are now stored inside the namespace, but some machines are stored in root. They are all in the same backup job. PVE Storage: PVE Backup job: PBS datastore: All other machines are inside of the namespace. All...
  4. Since 4 weeks it starts again with failing backups.

    Hi, for a long time I got always some failing backups from Prxmox clustr to the PBS. I also reported this long time ago. Then, 3 month ago, after somenew updates it worked like charm. Now, since arround 3 or 4 weeks, again after some updates, it starts to fail on many machines. Here is one...
  5. After latest update some VMs had no network

    Hi, after the lates update (ceph) some machines had no network. Circumstances: Firewall enabled on network card level, but disabled firewall of VM and disabled firewall on node and cluster. After removing the firewall flag on the network card level it starts to work again. Then I was also...
  6. Debian update with open-vswitch stopped networking

    Hi, this morning I installed the latest debian updates on our cluster. I do 4 servers at once. 3 of the first 4 were losing the network connection. All 3 of them uses OVS the 4th is using linux bridges, The last message on the proxmox console was always, that it is not possible to start...
  7. corosync was not able to come back

    Hi, last friday we had, unfortunately, a loop in our network. Maybe for 60 to 120 seconds, then I pulled the connector which causes the loop. After this everything looks fine again, until ... someone wants to login to our proxmox cluster: it was not possible via web. Luckily it was possible via...
  8. One server always failing the backup

    Hi, we are on the latest version (2.1-2) and latest kernel (5.3.19-2) and we make many backups to this PBS. But one server from a Proxmox cluster 7.1-7 always fails. Ok, it's a big server . disk-0 100G disk-1 512G disk-2 512G disk-3 512G disk-4 512G disk-5 512G Disks are on CEPH. Network is...
  9. [SOLVED]ProxMox 7.0-8 no graphs in the web GUI after upgrade from 6.4-11

    After a sucessfull upgrade from latest 6.4 to 7.0 I see only empty graph fields in the dashboard. Doesn't matter if I check the PVE node, or the VMs of the node. For testing, it is a single PVE node. Any ideas?
  10. MTU not respected after enabling Cluster firewall

    Hi, strange things happens: We have a small cluster with 4 pves. All of them has vmbrs with a MTU of 9000 cause of ceph speed, 2 of them with a bond, but that's not important. The client VMs uses a MTU of 1500 for the internet interface. Every thing worked fine, large udp packets were...
  11. pve shows failed, pbs shows ok

    Hi, last night I see the following: pve 6.3-6 INFO: Starting Backup of VM 134 (qemu) INFO: Backup started at 2021-04-22 01:01:26 INFO: status = running INFO: VM Name: DC001-10000 INFO: include disk 'scsi0' 'hdd-1:vm-134-disk-0' 100G INFO: backup mode: snapshot INFO: ionice priority: 7 INFO...
  12. Problems with big sync job

    Since in the 'national' forum no one gaves an answer... I have a problem with a big sync job. I sync all the data from one PBS to an other at an other location. After many tries I have now from all VMs something on the sync PBS. But it fails daily on 2 images: ct/129 and vm/100 with - broken...
  13. Probleme mit großem Sync Job

    Wir habe einen PBS1 auf den die Backups gemacht werden. Ein PBS2 an einem anderen Standort soll dort alles mittels 2er Sync-Jobs holen. Das Problem ist anscheinend, dass eine VM, unser file server, 2.7TB hat und es schon 6 (inkrementelle) Backups gibt. Der Sync job brach schon des öfteren ab...
  14. Good way to backup from several PVE clusters to one PBS (I hope)

    I thought this would be interresting for others too: If you want to use a central PBS for more then one cluster, you run into the problem of double IDs. Ok, you can use different datastores, but then you have to know the expected sizes. We did an other aproach: We build one big datastore and...
  15. Changing vlan-id and ifupdown2 fails 6.3.3

    Hi, we are using ProxMox 6.3.3 with installed ifupdown2 packet. If I change the vlan-id of a linux-vlan inteface where the vlan-id is not in the interface name and apply it, it looks good (no error), but with cat /proc/net/vlan/config you can see that the old vlan-id is in use. I need to run...
  16. PBS restore lxc fails

    I use a PVE 6.2-12 and a PBS 0.9-1. When I try to restore a container to a different id I get Error: error extracting archive - error at entry "random": failed to create device node: Operation not permitted (os error 1) TASK ERROR: unable to restore CT 303 - command 'lxc-usernsexec -m...
  17. Update zu 6.1.8 legt Server lahm

    Wir haben open-vswitch am Laufen. Beim Update von 6.1.7 zu 6.1.8 bricht die VNC Konsole ab wenn der Punkt openvswitch erreicht ist. Geht man dann vor Ort auf die Konsole ist das ganze Netzwerk platt. /etc/init.d/openvswitch restart liefert dann genau die gleichen Fehler. Es hilft nur ein...
  18. Wie entfernt man eine subscription?

    Klingt komisch, aber ... Zum ersten Test wurde ein kleines Cluster aufgebaut. Der erste Server erhielt eine Premium subscription. Es sollten dann aber (für Support) alle die gleiche Subscription haben. Nachdem nun der Kunde aber nicht für alle (zum Testen) die Premium Lizenz kaufen will, wurde...
  19. Snapshots on CEPH

    Hi, at the weekend we run into a problem: We made snapshots of windows servers for backups to transport the images. In one case the windows server immediately rebootet and did not found his boot drive anymore. We had to completely stop the server and start it again. Then, fortunately, the server...
  20. Wenn Backup Probleme macht werden VMs blockiert

    Hallo, wir sichern auf ein FreeNAS über NFS. Wenn der FreeNAS nicht mehr erreichbar ist während des Backupjops, kann man mit allen QEMUs und LXCs nicht mehr kommunizieren. Auch in der GUI bekommen die VMs rote Kreuze. Zweitens werden oftmals LXCs nicht mitgesichert, weil noch ein vzdump...
