Hello,

I ‚ve setup a test lab with 3 nodes installed with centos 7

I configured manualy gluster fs. Glusterfs is up and running

[root@kvm380 ~]# gluster peer status

Number of Peers: 2

Hostname: kvm320.durchhalten.intern

Uuid: dac066db-55f7-4770-900d-4830c740ffbf

State: Peer in Cluster (Connected)

Hostname: kvm360.durchhalten.intern

Uuid: 4291be40-f77f-4f41-98f6-dc48fd993842

State: Peer in Cluster (Connected)

After that I deployed a selfhosted engine

And add the two other hosts, at the beginning it looks good, but without changing anything I got following error by two hosts

!	20.12.2018 11:35:05	Failed to connect Host kvm320.durchhalten.intern to Storage Pool Default

Before glusterfs I had a setup with nfs on 4. Server

Where is the problem?

thx
