Hi,

removed partition signatures with wipefs and run deploy again: this time the creation of VG and LV worked correctly. The deployment proceeded until some new errors... :-/


PLAY [gluster_servers] *********************************************************

TASK [start/stop/restart/reload services] **************************************
failed: [ha1.domain.it] (item=glusterd) => {"failed": true, "item": "glusterd", "msg": "Could not find the requested service glusterd: host"}
failed: [ha2.domain.it] (item=glusterd) => {"failed": true, "item": "glusterd", "msg": "Could not find the requested service glusterd: host"}
failed: [ha3.domain.it] (item=glusterd) => {"failed": true, "item": "glusterd", "msg": "Could not find the requested service glusterd: host"}
    to retry, use: --limit @/tmp/tmp5Dtb2G/service_management.retry

In start/stop/restart/reload services it complain about "Could not find the requested service glusterd: host". GlusterFS must be preinstalled or not? I simply installed the rpm packages manually BEFORE the deployment:

yum install glusterfs glusterfs-cli glusterfs-libs glusterfs-client-xlators glusterfs-api glusterfs-fuse

but never configured anything.

For firewalld problem "ERROR: Exception caught: org.fedoraproject.FirewallD1.Exception: INVALID_SERVICE: 'glusterfs' not among existing services Services are defined by port/tcp relationship and named as they are in /etc/services (on most systems)" I haven't touched anything... it's an "out of the box" installation of CentOS 7.3.

Don't know if the following problems - "Run a shell script" and "usermod: group 'gluster' does not exist" - are related to these... maybe the usermod problem.

Thank you again.

Simone
