Hi Surya,

It is already customer setup and cant redeploy again.
Enabled debug for brick level log but nothing writing to it.
Can you tell me is any other ways to troubleshoot  or logs to look??

Hi Surya,

I have enabled DEBUG mode for brick level. But nothing writing to brick log.

gluster volume set vol_3442e86b6d994a14de73f1b8c82cf0b8 diagnostics.brick-log-level DEBUG

sh-4.2# pwd
/var/log/glusterfs/bricks

sh-4.2# ls -la |grep brick_e15c12cceae12c8ab7782dd57cf5b6c1

Hi Shaik,

Can you check what is there in brick logs? They are located in /var/log/glusterfs/bricks/*? 

Looks like the samba hooks script failed, but that shouldn't matter in this use case.

Also, I see that you are trying to setup heketi to provision volumes, which means you may be using gluster in container usecases. If you are still in 'PoC' phase, can you give https://github.com/gluster/gcs a try? That makes the deployment and the stack little simpler.

Hi,


Bricks are in offline and  unable to recover with following commands


gluster volume heal <vol-name>


gluster volume start <vol-name> force


But still bricks are offline.
