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_...
<http://www.ovirt.org/documentation/admin-guide/chap-Working_with_Gluster_...
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
I see that bricks
are mounted in /gluster/brick3 and that is the reason
it does not show anything in "Brick Directory" drop down filed. If
bricks are mounted under /gluster_bricks then it would have detected
automatically. There is an RFE which is raised to detect bricks which
are created manually.
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?
No, you do not need to
change anything for the new volume. But if you
plan to enable o-direct on the volume then you will have to disable/turn
off remote-dio.
