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

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
* Starting glusterd service glusterd [fail]
/usr/local/sbin/glusterd: option requires an argument -- 'f'
Try `glusterd --help' or `glusterd --usage' for more information.
13. checking glusterd log file found that OS drive was running out of space
output : [2019-01-15 16:51:37.210792] W [MSGID: 101012] [store.c:372:gf_store_save_value] 0-management: fflush failed. [No space left on device]

14. cleared some space in OS drive but still, service is not running. below is the error logged in glusterd.log
