<guerby> | Ramereth, h01ger netconsole is about the ony way to diagnose this kind of issue in my experience
<guerby> | h01ger, setup rsyslogd on one of the gccserver then it's just one modprobe netconsole
<guerby> | h01ger, since the machine are on the same LAN
<guerby> (if not on the same LAN, modprobe netconsole netconsole=+@${IPSRC}/eth0,514@${IPRSYSLOG}/${GWMACADDR} )
<guerby> where GWMACADDR is 00:11:22... your gateway MAC
<guerby> saved the day lots of time here :)
<guerby> found this ext4 bug thanks to it, CVE :
<guerby> "Red Hat would like to thank Laurent Guerby for bringing this to our attention." and /me thanks netconsole :)
<Ramereth> ya, netconsole is very nice to find odd kernel issues
<h01ger> | and you recommend to have that running all the time on all the nodes? or only when we suspect probs?
<Ramereth> we currently have it running all the time on all physical nodes
