Atin,
I have copied the content of 'gfs-tst' from vol folder in another node. when starting service again fails with error msg in glusterd.log file.

This is a case of partial write of a transaction and as the host ran out of space for the root partition where all the glusterd related configurations are persisted, the transaction couldn't be written and hence the new (replaced) brick's information wasn't persisted in the configuration. The workaround for this is to copy the content of /var/lib/glusterd/vols/gfs-tst/ from one of the nodes in the trusted storage pool to the node where glusterd service fails to come up and post that restarting the glusterd service should be able to make peer status reporting all nodes healthy and connected.

Hi,

In short, when I started glusterd service I am getting following error msg in the glusterd.log file in one server.
what needs to be done?

In long, I am trying to simulate a situation. where volume stoped abnormally and 
entire cluster restarted with some missing disks.

My test cluster is set up with 3 nodes and each has four disks, I have setup a volume with disperse 4+2. 
In Node-3 2 disks have failed, to replace I have shutdown all system

below are the steps done.

1. umount from client machine
2. shutdown all system by running `shutdown -h now` command ( without stopping volume and stop service)
3. replace faulty disk in Node-3
4. powered ON all system
5. format replaced drives, and mount all drives
6. start glusterd service in all node (success)
7. Now running `voulume status` command from node-3
output : [2019-01-15 16:52:17.718422]  : v status : FAILED : Staging failed on 0083ec0c-40bf-472a-a128-458924e56c96. Please check log file for details.
8. running `voulume start gfs-tst` command from node-3
output : [2019-01-15 16:53:19.410252]  : v start gfs-tst : FAILED : Volume gfs-tst already started

9. running `gluster v status` in other node. showing all brick available but 'self-heal daemon' not running
@gfstst-node2:~$ sudo gluster v status
Status of volume: gfs-tst

10. in the above output 'volume already started'. so, running `reset-brick` command
   v reset-brick gfs-tst IP.3:/media/disk3/brick3 IP.3:/media/disk3/brick3 commit force

output : [2019-01-15 16:57:37.916942]  : v reset-brick gfs-tst IP.3:/media/disk3/brick3 IP.3:/media/disk3/brick3 commit force : FAILED : /media/disk3/brick3 is already part of a volume 

11. reset-brick command was not working, so, tried stopping volume and start with force command 
output : [2019-01-15 17:01:04.570794]  : v start gfs-tst force : FAILED : Pre-validation failed on localhost. Please check log file for details

12. now stopped service in all node and tried starting again. except node-3 other nodes service started successfully without any issues.

in node-3 receiving following message.

sudo service glusterd start
