Six 9's http://six9s.com Just another WordPress weblog Sat, 22 Oct 2011 06:27:41 +0000 en hourly 1 http://wordpress.org/?v=3.2.1 Bugzilla Tools http://six9s.com/2011/10/21/bugzilla-tools/ http://six9s.com/2011/10/21/bugzilla-tools/#comments Sat, 22 Oct 2011 06:14:09 +0000 admin http://six9s.com/?p=12 I’ve been playing around with writing some python tools to get data into and out of bugzilla. I’ve dumped them in google code at https://code.google.com/p/gardens-bugzilla-tools/

Otherwise the sqlldr silently fails.

WTF? If it dies I want it dead, as they say, shoot the other node in the HEAD. To fix, create the fence_xvm as a shared fence and then manually edit the cluster.conf file and add option=”off” to the fence section. Stupid stupid stupid

Finally figure out how though
“phys:/dev/device,sda,w!”
The important part is the ! after the w. This is to force it to mount.

Great list of things to check that you never think of. Especially the line endings. That has messed up my puppet configurations more than anything else.

Also

Apparently they try to aggregate packets over all connections and in releases previous to 5.2 would cause a kernel panic. You can tell if you are having a problem by NUMEROUS syslog messages saying “recieved packets cannot be forwarded while LRO is enabled”. To fix this issue you need to add the following line to modprobe.conf
options bnx2x diable_tpa=1
