@fabian : Is there a doc/manual that explains how to properly work with backups & snapshots. (as well as how to manage snapshot when moving VMs around). We use snapshot for CI and automated testing. However, not having restorable (*) backups or not being able to move the VMs seems like an issue...

Hi, For information, I have extracted the raw file from the zst despite being to short. Renamed appropraitely, copied to and image storage and run a qm rescan. raw disk image appeared in my vm, and after reattachment successfully booted. As far as I can see my VM now runs. But I lost the...

Ok, I can do that. The snapshots are stored on a brand new NAS with raid5 BTRFS. I would not expect file corruption on 4 different snapshots. This mean that my backup are corrupted despite reporting success. I guess this means : - the VM is lost, - I should check all my VM backups? Is...

No it's acommercial product. It was an option of the acronis backup suite. But it used to be quite cheap for a single license. https://www.acronis.com/en-us/technology/universal-restore/

Hi, Did you try acronis universal restore (I am not sure it is still called like this today)? It can do magic fixing mismatched drivers at boot time, and let you boot back into the system so that you can install the drivers needed to match the hardware.

Hi, I needed to restore a VM today, and to my surprise the restore failed, with a short vma error _30-00_07_13.vma.zst : Decoding error (36) : Restored data doesn't match checksum vma: restore failed - short vma extent (608768 < 655872) My problem is that I have several snapshots, and they...

Yes something happened to this file between the last try to restore on the faulty HDD and the restart after changing the HDD. Can tell what or why. Yes You are right No Problem, I appreciate your efforts to understand my setup , and suggest solutions I did a : - VM creation, (got 149) -...

Ok, I am trying to save me a reinstall of the VM OS and software. I have 3 disks still available which contain the UEFI partition, OS partition and software. The lost partition on the lost disk was just hosting a developement database (and this data can be retrieved from the live db if needed)...

Well, I managed to mess up my backup and let backup rotation delete the backup file. I guess my current option short of creating a new vm, and reinstalling everything, is reconfiguring the hardware and reattach the existing drives?

Hi, HDD was replace but the VM definition seems to have been wiped in the operation. VM show only the vm number and almost no hardware. The VM was running despite the dead HDD, since it was using other VMDisk where the OS was stored. I can still see my VM storage disks in the console: Is...

Not sure, I used the "add lvm" from the proxmox gui to create a lvm on the disk. Nothing else on this partition except for that one VM. Ok I will try that. Thank you. Yes, it is a simple setup.

Hi, One of the drive has gone dead. SMART is in failed state, any disk operation fills the logs with errors, and slows everything down. This is not a system disk. The VM using this disk is stopped pending restore. Disk has just 1 LVM 8T partition, and will be replaced with a bigger disk. Is...

Ok, Below is the information. Let me know if I missed anything. Regards * Storage definition : ==== info about storage ==== # cat /etc/pve/storage.cfg dir: local path /var/lib/vz content backup,vztmpl,iso lvmthin: local-lvm thinpool data vgname pve content...

I agree that declaring the volume in pve and the LVM on top of it works and does not require any fstab entry. However, from what I understood, this only works when using the volume in raw for a single VM (thus using the full volume). I created an ext4 fs and mounted it so I can use qcow images...

Hello, I am new to proxmox, so I probably do the things in the wrong order. I have added to proxmox a iscsi volume. Mounted a LVM on it with an ext4 FS, and I can mount it fine. But I tried to insert it in fstab, so that it gets mounted at boot and VM using the FS can be started as well. This...
