Hi all,
Ok so active followers on this forum knows i have some major network problems with my 3 node proxmox installation using two HP 1810-24G v2 switches..
All nodes are configured with LACP and connected too each switch with only one network cable for each switch..
The switches are also trunked togeather with one network cable..
I have done some more troupleshooting..
my problem is this..
Say i need to boot my switches.. implementing a new firmware..
I update switch 3 and 2 and than reboot switch 3 and when it comes online reboots switch 2 and waits for it to come online..
when everything is up and i can ping all 3 nodes fine..
I log on to node0 and ping the two other nodes..
I log on to node 2 and ping the two other nodes..
I log on to node 1 and can't ping anything.. - I didn't test if i could ping my mashine over the VPN but i could connect to it using putty..
Ok so i decide to reboot node 1.. but this does not take effect right away.. so i try again to ping and now i CAN ping node 0 and node 2.. short after my reboot command takes effect and node 1 reboots..
When node 1 comes back online i recive major packet loose from node 0 and 2 AND my own mashine..
I can connect with a SSH from node 2 to node 1 and do a "service networking restart" command.. but i can clearly feel the packet loose as i type the command and wait for it effect..
Imidiatly after my service restart node 1 answers ping from all other nodes and my mashine over vpn..
ANYONE know why that happens..
I have seen this happen many times during switch failover test and network card failover test on each node.. testing network card mean i unpluck one network cable from one of the network cards and expect LACP to fail over correctly.. during these test this can happen to any number of nodes.. I have seen it happen too two nodes at a time... but usually it only happens to one... and it doesn't have to be node 1..
HELP!!!!
I will gladly provide ANY logs if you guys would tell where they are :)
