reboot one node case all other nodes backup stop

[starnetwork]

Hi,
in daily backup we did reboot to one of the servers
in case of that reboot, all other nodes stop the backup proccess
example:

INFO: Starting Backup of VM 117 (lxc)
INFO: status = running
ERROR: Backup of VM 117 failed - unable to open file '/etc/pve/nodes/server13nvme/lxc/117.conf.tmp.7676' - Permission denied

syggestions?

Regards,

Hi,

is this node a member of a cluster?
If yes, has this node quorum?

 

[starnetwork]

Hi,
1. yes, it's member of a cluster

2. after the reboot the node lost the quorum, after I rebooted all the nodes the quorum back to normal, it's look like the combination of backup and lost node from the cluster together Disrupted the work of the cluster

 

[wolfgang]

Do you have the backup and the corosync network on the same physical network?

 

[starnetwork]

yes,
we have total of 2 networks
1. Internet

2. internal network for Backups and cluster

 

[wolfgang]

Then this is an expected behavior your backup interupt the cluster communication and loos quorum.

Use a second ring[1]

maybe vlans will help here?

This will only work if you have a powerful switch. And I mean like a Campus switch.

openvswitch?

No.

we using 2x Broadcom BCM56846 10GbE Low Latency Switch

I don't know this switch but the specs look promising.
I think it is worth trying it.
