Hello,
I'm trying to create a new volume. I'm in 4.1.2
I'm following these indications:
http://www.ovirt.org/documentation/admin-guide/chap-Working_with_Gluster_
Storage/
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?
Thanks,
