>From the logs the following observations were made:

at 13:27:38 the glusterd restart has happened on node

[2018-10-12 13:27:38.467525] I [MSGID: 100030] [glusterfsd.c:2504:main]
0-/usr/sbin/glusterd: Started running /usr/sbin/glusterd version 3.12.2 (args:
/usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO)

At this time the volumes have to be synced in the handshake.
The handshake started around 13:27:45

and went till 13:27:59.876472 on

And the time the gluster volume delete for the volume iceberg-2-1-9-5 has been
[2018-10-12 13:27:59.875956]  : v delete iceberg-2-1-9-5 : SUCCESS

>From the above observation the delete was issued while the handshake was

As the handshake started before delete and the iceberg-2-1-9-5 was supposed to
be available in the cross checked file for handshake. And this was being synced
in the restarted node (
Now delete was issued and it deleted the entry as the node has come up. After
the delete completed successfully and removed the entry, the handshake has
created the entry for the iceberg-2-1-9-5. This is why the entry has
stage_deleted as false (before delete was issued it is false).

And to confirm further the entry is available only on the node that went
through a reboot ( and not in the other nodes.
