Re: [Gluster-devel] gluster server 3.0 segfaults on ibverbs setup

[Anders Litzell]

Hi everyone,

What I did:
I did an upgrade to an existing very small lab setup (one server, one 
brick, localhost only client). yum erase old rpm, yum localinstall new 
rpm and no change to config files, added --debug to init script.

The result:
A very similar segfault error to the original post and I'm hoping my 
data may be able to shed more light on this. Please see debug output 
below. Segfault happens 2-10 seconds after daemon start.

As a curiosity please note that nothing is written to the log files. All 
output to stdout EXCEPT last line with the segfault which is to stderr.
