I have a gluster volume that was created using an older version 4.x of oVirt.
This was so long ago I am not sure I remember how I did it except that I used
the wizard and the built in ansible job. I recently rebuilt my system that is
hyperconverged. The storage raid array (hardware backed) is in my hypervisor.
The engine is a stand alone external device. I am now at ver 4.5.7 of Ovirt.
I want to add my gluster brick back into the setup. I have reviewed the wiki
notes but they presume a new build, not my scenario. From what I read and
researched, I think I need to create a distributed brick. How do you do that
with just a single system when there is no replication to other hosts? Can
anyone share a general procedure?
##DIAGNOSTICS
[root@vmh /]# mount
...
/dev/mapper/gluster_vg_sda-gluster_lv_vmstore on /gluster_bricks/vmstore type
xfs
(rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=256k,sunit=512,swidth=2048,noquota)
[root@vmh /]# tail -n 1 /etc/fstab
/dev/mapper/gluster_vg_sda-gluster_lv_vmstore /gluster_bricks/vmstore xfs
defaults 0 0
[root@vmh /]# gluster volume create vmstore
vmh.tourville.org:/gluster_bricks/vmstore
volume create: vmstore: failed: The brick
vmh.tourville.org:/gluster_bricks/vmstore is a mount point. Please create a
sub-directory under the mount point and use that as the brick directory. Or use
'force' at the end of the command if you want to override this behavior.
[root@vmh /]# gluster volume create vmstore
vmh.tourville.org:/gluster_bricks/vmstore/vmstore
volume create: vmstore: failed: /gluster_bricks/vmstore/vmstore is already part
of a volume
[root@vmh /]# tree /gluster_bricks/
/gluster_bricks/

Do I need to force creation at this point? I just want to proceed cautiously
at this point as I am not super confident with gluster.
IE- [root@vmh /]# gluster volume create vmstore
vmh.tourville.org:/gluster_bricks/vmstore force
