restore and ssh lost

[filou0269]

Morning,
I have some problems with restore. My hypervisor is in proxmox 7. Backup are in storage local.
When i do a restore, with interface or with command line, i lost the ssh of my vms in this hypervisor after a certain time. And before the end of restore, the ssh go back.
Someone can help me ?

Is there any interesting sys error in Syslog/Journalctl during the backup job?

Thank you for the output !

Does the PVE GUI work when the SSH lost connection? If yes - what showing in the statics page in PVE Datacenter -> centreon-v6 -> Summary section [Network traffic] and [CPU usage]

Did you try to update the certificate using pvecm updatecerts --force?

 

[filou0269]

Hi,
yes the PVE GUI work without problems. I see network traffic and CPU usage, and no problem too. CPU usage fluctuates between 30-40%, and for Network Traffic :

For the pvecm, i dont use cluster now,
I test the use of proxmox before proposing it to my hierarchy

Thank again for your help.

Morning,
I do more tests.
when I look on one of the vms what is happening I see the following messages:


and it's the same for the other vm of the hypervisor.

Thank for help...

Can you test to set the bandwidth limit to the backup job? You can edit the /etc/vzdump.conf file (bwlimit) to set the bandwidth.

 

[filou0269]

Hi,
I did several tests to set the bandwidth. I modified the file with a value of 100 KBPS, 1000 KBPS and finally 10000 KBPS. It seems to work normally with these 3 values. I am redoing tests with heavier vm backups this afternoon.

Thank for your help really.

 

[filou0269]

Again me...
my test with a heavier backup again resulted in the same problem, same error message on the hypervisor vms:

I dont understand where is the problem...
