Hi Lixiaopo,
The logs which we are interested in are "/var/log/glusterfs/*" and
"/var/log/glusterfs/bricks/*" .
To generate statedump, run the below command (when there is a hang while
running the glusterfs_example)-
gluster volume statedump <volname> (i.e, in your case 'gluster volume
statedump dr')
The statedump info will then be copied to
"/var/run/gluster/*.dump.timestamp" files.
Please share those files as well.
Thanks,
Soumya

Thanks for the bt. Looks like brick process isn't responding here.
Please collect logs and statedump info of the brick process while there
is a hang.
To generate statedump, refer to the below link -
https://github.com/gluster/glusterfs/blob/master/doc/debugging/statedump.md
Thanks,
Soumya
