Im seeing that the timestamps on these log entries do not match the
time on the node.
gluster logs are in UTC format. That is the reason you might be
seeing a
different timestamp on your node and in the gluster logs.
The next steps
I stopped the glusterd service on the node with volume test1
I deleted it with: rm -rf /var/lib/glusterd/vols/test1
I started the glusterd service.
After starting the gluster service back up, the directory
/var/lib/glusterd/vols/test1 reappears.
Im guessing syncing with the other nodes?
yes, since you deleted it only one one
node.
Is this because I have the Volume Option: auth allow *
Do I need to remove the directory /var/lib/glusterd/vols/test1 on all
nodes in the cluster individually?
you need to remove the file
/var/lib/glusterd/vols/test1 on all nodes
and restart glusterd service on all the nodes in the cluster.
thanks

can you check if /var/log/glusterfs/etc-glusterfs-glusterd.vol.log
exists? if yes, can you check if there is any error present in that file ?

Running those four steps will remove the volume from your cluster . If
the volumes what you have are test volumes you could just follow the
steps outlined to delete them (since you are not able to delete from
UI) and bring back the cluster into a normal state.

since you have already removed the volume from one host in
the cluster and you still see it on another host you can do
the following to remove the volume from another host.<br>
<br>
1) Login to the host where the volume is present.<br>
2) cd to /var/lib/glusterd/vols<br>
3) rm -rf <vol_name><br>
4) Restart glusterd on that host.<br>
<br>
And before doing the above make sure that you do not have
any other volume present in the cluster.<br>
<br>
Above steps should not be run on a production system as you
might loose the volume and data.
<br>
<br>
Now removing the host from UI should succed.<br>
