I had a large Centos VM (32Gb) and to reduce the size of the backup I add a disk on my ceph storage with backup set to 0 (I toggle the no backup button and use a remote backuppc server for this area) and move all the data to this new storage (/dev/vdb). It remain less than 3GB on /dev/vda.
But...
My config is quite similar to yours: 3 nodes with same hardware on each node. I started installing proxmox (I have 2 hard drives with hardware raid1 for the OS) and setup HA as I was doing ten years ago (drbd, heartbeat, mon...). I had two 8TB additonal hard drive in each node, set up in...
Thanks Wolfgang for your answer.
I saw this new checkbox since proxmox4 but I do not understand clearly what it is and how to use it. Is there some detailed info about this ? I search for with the "vlan" keyword in the documentation (pdf) and look at the wiki but do not find help so I fallback...
Hi,
I am unable to setup a VLAN config on PVE 4.4. My error should be simple but I do not find it!
Context: 3 node cluster, node-3 only running a VM for testing the VLAN setup.
The running config:
On node-3 I have vmbr9 bridged on eth9.
VM103 on node-3 is VirtIO connected on vmbr9
The IP of...
Is there a way to do this while restoring a backup or cloning a VM ? I'm too interested in shrinking a big VM after moving out several gigabytes of data as it raise backup problems (large backup storing static data).

Did you check you have enought space available in /var/lib/vz ?
I felt in such problem with backing up large VM used for autoinstallation of linux PC, /var/lib/vz was not large enought to store several backups.
Sorry I can't provide help, I've no experience with BackupPC running on Debian, I only use Debian in proxmox context and all my linux (including backup server) are RedHat flavors.
My use is quite different than yours I think: I need high available storage and services for my servers, cluster, users desktop, data integrity and resilience of the config. But I have few users (10 to 20) and large data. SSDs are too much expensive for our organisation so I use slower but...
Hi Sebastian2000
and what about unsing ceph with several raid0 devices (I think raid10 is also for high bandwith) ? Replication of your data would allow you to move your VMs from one node to the other even if with a C6220 you have some spof with the fans, the bmc...
Howerver C6220 has only...
Thanks Fabian for this precision. May be this could become a new feature of proxmox, moving a "data disk" from one VM to another....
The context could be testing a new file server with a different linux version and switching to prod with just moving the disk which has the users data.
To set a final point to this thread, is there a way to move an unused disk from a VM to another ? The move option available in the GUI is only for changing the storage.
-> disk is removed from the stopped VM 103 (it appears as unused)
-> I've restored a backup of this VM with a new ID: 104...
Hi Fabian
It was so simple and my question was so stupid!
I had investigated "unused disks" last year in a proxmox training session but missunderstood this part about storage behavior in Proxmox.
In my defense there is only one small slide about this in documents provided but... Okay :oops...
Thanks Fabian for helping in this Backup/restore problem.
So I must:
1) restore the backup
2) from the interface add the additionnal disk (with same confguration I suppose)
3) then boot the VM
But, is it possible at step 2 to use the disk image associated with the previous VM ? It seams...
No idea ? Nor from proxmox users nor from proxmox team ?
Am I doing something wrong in this VM setup when I check the no-backup option for the additionnal disk (or may be not supported by the backup/restore proxmox tool)?
I'm surprised that nobody reach in this situation where VM backup can't be...
I'm still confused on howto backup/restore a VM with an additional disk not backed up....
I've run some test with "VM 103". Disk1 is the OS, disk2 is user data that I do not want to backup it with the OS as it is very large (on the VM in prod, not in this one where the test config has just a 8Gb...
Thanks czechsys to suggest working at the file config level, but could you provide some links I should (have) read about this ?
I'm sorry but proxmox is working very well and so I'm not famillar with its file-based admin level, GUI was enought until now for me even if last year, at Proxmox...
I've some troubles understanding backup/restore for a (CentOS) VM with Ceph storage, used as NFS server. Let say it is VM n. 100.
I've added a hard drive to this VM (virtio1) and it is located on my ceph RDB storage.
I do not want to backup this additionnal disk when I backup the VM as it is a...
Thanks for your reply Wolfgang,
I have not understood this was requested in the last sections of the tutorial....
If I set the BIOS to UEFI (the VM was installed with default Bios settings) does it mean I must reinstall the VM ?
I had set "machine: q35" (without understanding what it was...
I'm trying to use pci passthrought for an old nvidia GeForce 9300 GE GPU in a win7 VM.
The GPU is detected in the guest os, driver is installed and updated but I still get a code 43 error.
I haven't more detailed information and this peripheral is disabled in the VM
The config is based on the...
