Re: 回复： 回复： 回复：   glfs_creat this method hang up

Hi Lixiaopo,
Looks like there is some issue/disconnect on the brick-server side. I am not much familiar with that code base. So have requested Pranith to look into the same. He is currently busy with few blocker issues, and so may take a little while to debug this.
Meanwhile I request people familiar with brick server code base to take a look at the logs. 

Thanks,
Soumya

        The java api that use uuid as file name works fine.

Thank you in advance.

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
