Hello,
I'm trying to create a new volume. I'm in 4.1.2
I'm following these indications:

When I click the "add brick" button, I don't see anything in "Brick Directory" dropdown field and I cannot manuall input a directory name.

On the 3 nodes I already have formatted and mounted fs

[root@ovirt01 ~]# df -h /gluster/brick3/
Filesystem                  Size  Used Avail Use% Mounted on
/dev/mapper/gluster-export   50G   33M   50G   1% /gluster/brick3
[root@ovirt01 ~]# 

The guide tells 

7. Click the Add Bricks button to select bricks to add to the volume. Bricks must be created externally on the Gluster Storage nodes.

What does it mean with "created externally"? 
The next step from os point would be volume creation but it is indeed what I would like to do from the gui...

Thanks,
Gianluca


It seems I have to de-select the checkbox "Show available bricks from host" and so I can manually the the directory of the bricks

BTW: I see that after creating a volume optimized for oVirt in web admin gui of 4.1.2 I get slight option for it in respect for a pre-existing volume created in 4.0.5 during initial setup with gdeploy.

NOTE: during 4.0.5 setup I had gluster 3.7 installed, while now I have gluster 3.10 (manually updated from CentOS storage SIG)

Making a "gluster volume info" and then a diff of the output for the 2 volumes I have:

new volume ==   <
old volume  ==    >

Do I have to change anything for the newly created one?
