Title: sme 9b3 Change to jumbo MTU how?
Post by: tomsmsp on March 13, 2014, 11:24:15 PM

Want to try jumbo frames on my e1000 nic.  I've got it working on other boxes.  Want them all the same.

MTU = 9000    Needs a file added to /etc/sysconfig...somewhere?   ifcfg-eth0 says do not touch.  changes will be lost.

Then a couple of signal events probably.     Thx.

Code: [Select]

db configuration setprop InternalInterface MTU 9000
signal-event post-upgrade
signal-event reboot

Not tested, but should work

Those commands do run and set the mtu = 9000 in ifcfg-eth0 properly. 
ping tests between a debian nas and my main win pc work great.
"                 "         the deb nas and sme don't.   
"                "          sme and anything don't.
Win 8 file copy hangs too.   So sme with this jumbo frames at 9000 unlike regular centos 6 or debian doesn't work.

Maybe samba needs a tweak or something else.

Tests ran used ping -M do -s  8972  <dest IP>  and on win ping -f -l 9000 <dest ip>

What's the command to undo this change?

I successfully reversed the setting with delprop.  Thanks   

I will try setting the mtu in proxmox ve then add this setting to the sme vm.  Doh.

Edit:  Ok.  Now it works after doing the above in pmox.
