gluster
Segmentation fault (core dumped)
The "gluster volume status test" command returns the error "Segmentation fault (core dumped)"
I have a setup of 15 nodes, each node has 36 Hard drives (Each 4TB Capacity). So my total brick count is 540 My volume is disperse-data 11 redundancy 4 transport tcp (11+4 Setup with 15 nodes)
The status command worked fine till I added the 33rd set of bricks i.e when my brick count reached 495 it worked fine and returned the status of volume, However after adding the 34th Brick set, I got the error "Segmentation fault (core dumped)" i.e my total brick count reached 510 now.
What is the reason behind this error? Someone, please help with this ASAP
Thank You SRP
Could you please share the core dump? if possible, please take the core into gdb and share output of "thread all apply bt" output. Which gluster version are you running?
@pranithk Is there any updates from your end on this problem? Do you want me to provide the dump? The similar issue reported in the ticket #4323 already has the dump in it.

Could you attach the dump from your setup also? Sometimes issues could be slightly different. Better to have more information
@pranithk I got the below alone in my dump file, this is it or am I missing something? If Yes, Please let me know.
