Issue with Vmbr

[aurelien.guillaume]

HI,

I'm contacting you because my proxmox is acting with a strange behavior,
I'm on a 3 node cluster, with same hardware, and only one node is impacted,

when proxmox start, no issue, but after few hours / days, if I reboot a VM (any VM present of the impacted node) the VM can't get internet back, if I reboot 5 VM, all 5 will be impacted, it touch as well windows or linux VM,

only fix to recover internet on the VM is to reboot the proxmox node itself,

is this a known bug ?

what troubleshoot I can done for this ?

Thanks

 

[remark]

Is there anything unusual in /var/log/syslog?
And please show /etc/network/interfaces from all 3 nodes.

on this node I've quite a lot of log like these

smartd[4884]: Device: /dev/sda [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 68 to 69 smartd[4884]: Device: /dev/sdc [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 65 to 66 corosync[5699]: [TOTEM ] Retransmit List: 401bb smartd[4884]: Device: /dev/sde [SAT], CHECK POWER STATUS spins up disk (0x81 -> 0xff) smartd[4884]: Device: /dev/sdg [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 71 to 72 smartd[4884]: Device: /dev/sdg [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 29 to 28

even if the server is new and the smart status coming from the server administration interface is totally good

exept this log, I see nothing strange


I forgot to add that only VM are impacted, proxmox itself have no issue at all accessing network

for network settings,
impacted server :
