Cluster - Backup on other node disk

[EdouardP]

Hi all,

I have a 2-nodes cluster. Nodes names are proxmox1 and proxmox2.

I have a VM with ID 100 on proxmox1 and I would like to backup it on a backup disk on proxmox2.

From the GUI, when I open proxmox2 and I click on Backup disk, I have this error:

mount error: mount.nfs: access denied by server while mounting proxmox2:/backups/ (500

I understand that there is some permission problem, but I'm not sure what to do to solve it..

Any idea ?

Thanks !
Edouard

please post more information

cat /etc/pve/storage.cfg

Sure, with pleasure !

dir: local
    path /var/lib/vz
    shared
    content images,iso,vztmpl,backup,rootdir
    maxfiles 30

nfs: backups
    path /mnt/pve/backups
    server proxmox2
    export /backups/
    options vers=3
    content backup
    maxfiles 15

Thanks !

how do you have configured the nfs server?

 

[tom]

dir: local path /var/lib/vz shared

/var/lib/vz is not a shared storage, please remove the "shared" flag.

@tom: Ok, I'll remove the 'shared' flag for 'local', thank you for that.

@dcsapak: honestly, I did it few months ago, I've followed a guide and I'm not sure how I did it.. Is there a conf file I can cat for you ?

Actually, I think I was wrong with this shared disk, I explain the situation:
My proxmox1 have a 120Go SSD hard drive with my production website on it.
My poxmox2 have a 2To hard drive with my integration website and other stuff.
So what I would like is to backup my production VM (running on proxmox1) directly on proxmox2, without shared the backup disk, because currently my backup disk is about 20Go and I can't increase it... So my 2To hard drive on proxmox2 is a bit useless at the moment.

As you can see I need your advice to setup my backup strategy properly.

Thank you very much !
