Hi Markus, you're right. glusterfs creates a thread which reads from /dev/fuse only after it establishes connection with server. Since connection is not established even once, the thread is not created and hence any operation on mount point hangs forever. I am not sure whether this can be treated as a bug. regards, On Tue, Aug 26, 2008 at 5:33 AM, Markus Fenske <iblue@xxxxxxx> wrote: > Hello, > > It seems like I have found a bug. > > I run 1.3.11, my
