Hi Sanju,

Please find requested information.

Sorry to repeat again I am trying start force command once brick log 
enabled to debug by taking one volume example.
Please correct me If I am doing wrong.

So it looks like, neither gf_is_service_running() 
nor glusterd_brick_signal() are able to read the pid file. That means 
pidfiles might be having nothing to read.

Can you please paste the contents of brick pidfiles. You can find brick 
pidfiles in /var/run/gluster/vols/<volname>/ or you can just run this 
command "for i in `ls /var/run/gluster/vols/*/*.pid`;do echo $i;cat 
$i;done"

Hi Shaik, 

Can you please provide us complete glusterd and cmd_history logs from all 
the nodes in the cluster? Also please paste output of the following 
commands (from all nodes): 
1. gluster --version 
2. gluster volume info 
3. gluster volume status 
4. gluster peer status 
5. ps -ax | grep glusterfsd

"External email. Open with Caution" 
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. 

-Amar

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.
