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). Patrick (using PVE 4)

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.

Why don't you use a VM or a LXC container to run your backuppc server on your proxmox host ? I'm not sure it is a good choice to run this on the host.

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...
