Until this week we backed up our VMs using just built in backup by Proxmox VE to an NFS storage. We really had sometimes failed backups (I would better say: failed backup tasks, not failed backups): 1) Two backup schedules sometimes overlapped which would cause the latter backup task to fail; 2)...

Hello, I faced a strange problem with one of my VMs on Proxmox VE. This is an Ubuntu VM which resides on a ZFS thick storage. On 31 October 2026 I reconfigured the VM, added CPUs and RAM but did not reboot the VM to apply changes because the VM was in use and these additional resources were not...

I found the solution in the outdated article from proxmox wiki I changed the following parameters: node.startup: manual => automatic node.session.timeo.replacement_timeout: 120 => 15 in the /etc/iscsi/iscsid.conf and /etc/iscsi/nodes/<TARGET>/<PORTAL>/default The problem is gone. The latest...

The delay in the VM autostart settings does not help when it is the first VM to autostart.

Hello, I found out that after proxmox starts VMs which have their disks on iscsi storage and are expected to autostart fail to do this because their storage is not ready yet. By the time I login to the web gui I can start the VMs by hand with no problem: ........... Aug 12 07:00:11 hv02...

I see. Thank you very much again for your comprehensive explanations!

Yes, after leaving out the -Zn option the problem seems to disappear. I remember that I added this option because there was an advice somewhere that this can speed up the provisioning of the big pool which now seems a bit odd to me when I again read the man page about this option. As the man...

So, after repeating all the steps in Step 2 and restoring a VM from backup to the new lvm-thin storage (where the vm is corrupted again) I see the following: ~# lvdisplay '/dev/vg_local/lv_thin_local' --- Logical volume --- LV Name lv_thin_local VG Name...

Thank you for the hint! I will repeat step 2 and check metadata usage.

Thank you. But I still do not understand why limiting hdsize is a bad option while it exactly does what I need?

This is sort of test lab so during proxmox installation I chose hdsize 15GB to try to limit the storage size proxmox takes by itself. IIRC, during the install proxmox said that it would not create data partition because of too small hdsize. According to wiki: hdsize Defines the total hard disk...

Hello, I have a strange situation with my single node installation. I have a free space on the proxmox install disk /dev/nvme0n1: lsblk ... nvme0n1 259:0 0 476.9G 0 disk |-nvme0n1p1 259:1 0 1007K 0 part |-nvme0n1p2...

Hello. After backup some Linux KVM VMs regularily seem to have done hard reset and cannot boot anymore. I fix these VMs by booting from live CD and using gpart -W /dev/sda /dev/sda and grub install Is there a way to fix that? PVE Manager version 5.3.7
