Hi Tobias,<div><br></div><div>From what I know, you have to increase it on the Ethernet interface, not the bridge.</div><div><br></div><div>I may be wrong, so if someone else knows please correct me.</div><div><br></div>

Hello everyone,<br>
<br>
<br>
I have two ProxMox Server and I am using DRBD to sync the VM-Images between this both machines. Every Server is a DRBD Master and a DRBD Slave for the other one too…<br>
But my DRBD speed is not very high. I think I need to increase the MTU of the VMBR-Interface. I tried that, but I got and error. Any Ideas anyone?<br>
<br>
<br>
iface eth2 inet manual<br>
broadcast 10.2.7.255<br>
network 10.2.7.0<br>
mtu 9000<br>
<br>
auto vmbr1<br>
iface vmbr1 inet static<br>
address 10.2.7.136<br>
netmask 255.255.255.0<br>
bridge_ports eth2<br>
bridge_stp off<br>
bridge_fd 0<br>
pre-up ifconfig eth2 mtu 9000<br>
<br>
<br>
<br>
After restarting network I get this error:<br>
<br>
<br>
Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).<br>
if-up.d/mountnfs[vmbr0]: waiting for interface vmbr1 before doing NFS mounts ... (warning).<br>
SIOCSIFMTU: Invalid argument<br>
Failed to bring up vmbr1.<br>
done.<br>
<br>
<br>
<br>
<br>
Thanks and Regards!<br>
