[Gluster-users] df command shows transport endpoint mount error on gluster client v.3.10.5 + core dump

Hi Ashish,

thank you for your answer.
Do you need complete client log file only or something else in particular?
Unfortunately, I never used ?bt? command. Could you please provide me an usage
example string?

I will provide all logs you need.
Thank you again,
Mauro

[Gluster-users] df command shows transport endpoint mount error on gluster client v.3.10.5 + core dump

Hi, 

Following are the command to get the debug info for gluster - 
gdb /usr/local/sbin/glusterfs  <core file path> 
Then on gdb prompt you need to type bt or backtrace 
(gdb) bt 
You can also provide the output of "thread apply all bt". 
(gdb) thread apply all bt 
Above commands should be executed on client node on which you have mounted the
gluster volume and it crashed.
However, I am not sure if you have enabled the generation of core dump on your
system and have setup path to coredump.

Hi Ashish, 

thank you for your answer. 
Do you need complete client log file only or something else in particular? 
Unfortunately, I never used ?bt? command. Could you please provide me an usage
example string?

I will provide all logs you need. 
Thank you again, 
Mauro

Hi Mauro, 

We would require complete log file to debug this issue. 
Also, could you please provide some more information of the core after attaching
to gdb and using command "bt".

Dear Gluster Users, 

I implemented a distributed disperse 6x(4+2) gluster (v.3.10.5) volume with the
following options:

[root at s01 tier2]# gluster volume info

I also started a long write test (about 69 TB to be written) from different
gluster clients.
One of this client returned the error "Transport Endpoint is not
connected" during the rsync copy process.
A core dump file has been generated by the issue; this is the core dump content:

"/core.15795" is a core file. 
Please specify an executable to debug. 

No problem detected on the gluster servers, no brick down and so on... 

Anyone of us experienced the same problem? 
If yes, how did you resolve it? 

You can find the client "/var/log/messages" and
"/var/log/glusterfs" log files content.
Thank you in advance.

[Gluster-users] df command shows transport endpoint mount error on gluster client v.3.10.5 + core dump

Hi Ashish,

in attachment you can find the gdb output (with bt and thread outputs) and the

Thank you for your support.
