[Gluster-devel] gluster IRC and use systemtap can't output glusterfs backtrace

Wed May 14 06:29:25 UTC 2014

What do you mean by the back trace is not continuous?

GlusterFS code is based on asynchronous event based programming built around non-blocking
sockets. So, there is a call and a call back that execute in different threads
of execution in the mount process, for every file operation on the mount.This 
could be one of the reasons why the back trace appears discontinuous.

If you think the backtrace appears truncated then check man stap(1) for increasing
default backtrace size (See MAXBACKTRACE).

Hope that helps,
Krish
