Hi Atin,
This is the steps exactly I have done which caused failure. additional to this node3 OS drive was running out of space when service failed. so I have cleared some space in OS drive but still service failed to start.
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
* 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

I'm not very sure how did you end up into a state where in one of the node lost information of one peer from the cluster. I suspect doing a replace node operation you somehow landed into this situation by an incorrect step. Until and unless you could elaborate more on what all steps you have performed in the cluster, it'd be difficult to figure out the exact cause.On Wed, Jan 30, 2019 at 7:25 PM Amudhan P <amudhan83@xxxxxxxxx> wrote:Hi Atin,yes, it worked out thank you.what would be the cause of this issue?On Fri, Jan 25, 2019 at 1:56 PM Atin Mukherjee <amukherj@xxxxxxxxxx> wrote:Amudhan,So here's the issue:In node3, 'cat /var/lib/glusterd/peers/* ' doesn't show up node2's details and that's why glusterd wasn't able to resolve the brick(s) hosted on node2.Can you please pick up 0083ec0c-40bf-472a-a128-458924e56c96 file from /var/lib/glusterd/peers/ from node 4 and place it in the same location in node 3 and then restart glusterd service on node 3?On Thu, Jan 24, 2019 at 11:57 AM Amudhan P <amudhan83@xxxxxxxxx> wrote:Atin,Sorry, i missed to send entire `glusterd` folder.
