Problem with VM using NFS storage

[sparrow]

Hello community, I have configured on my pve5.4-3 a backup solution for
my VMs backups. This solution deployed on my network use an open source
NAS with OpenMediaVault-4.1.3 Arrakis with an NFS server which serves as external
storage for my Proxmox VE. The solution is described at:
sysadminsdecuba.com/2019/07/si…n-openmediavault-virtual/
You can traslate it to English, so you can understand what I made.
That guide uses OMV Erasmus, but is the same with Arrakis,


The problem is that when I create a VM with a secondary HDD using my
external storage (wich is a virtual NAS using a real HDD connected to my
Proxmox, but not mounted on it, it is mounted on the virtual NAS) when I
start to poblate that disk of info, the copy of information is droped
when it has transfered 1.5GB more or less. I tested this with an FTP and
with Nextcloud and it happend the same.


This solution of virtual NAS works fine for the backup system of
Proxmox, and I have already more than 10GB of backups of my VMs in my
virtual NAS, but there is something about the virtual disks on my NAS
that limit the transfers or some missing quota...


If anyone can help me, please reply my post. This solution I made is for
my PAN (Personal Area Network) is a server I use in my house wich
serves as laboratory.

I think I solved the problem. It´s possible that the problem were with the mounting of the secondary HDD of VM, that I havent mounted permanently, so the info went to the VM instead the VM of its secondary disk on the NAS and started to droop packets. I made some tests, using transfers up to 17GB and it was OK. I will check this on my server tomorrow, because this test was on a virtual Proxmox.
