[ovirt-users] Glusterfs storage

Tue Mar 3 09:52:29 UTC 2015

I have 2 hosts with hosted engine in the firts host. The second host also has the Domain Storage for the 2 hosts (Glusterfs). 

The Storage Domain is in active status. 
In the firts host I can see : /usr/sbin/glusterfs --volfile-server=host2.domain.tld --volfile-id=/gv0 /rhev/data-center/mnt/glusterSD/host2.domain.tld:_gv0 
What I did for Gluster in the second host: 
# yum -y install glusterfs-server 

# systemctl start glusterd 

# systemctl enable glusterd 

# gluster volume create gv0 transport tcp host2.domain.tld:/home2/brick1 

# gluster volume start gv0 

# gluster volume info 
Volume Name: gv0 
Type: Distribute 
Volume ID: 6ccd1831-6c4c-41c3-a695-8c7b57cf1261 
Status: Started 
Number of Bricks: 1 
Transport-type: tcp 
Bricks: 
Brick1: host2.domain.tld:/home2/brick1 

# chown 36:36 /home2/brick1 

Now I cannot attach the ISO Domain 

The error in the engine.log: 

2015-03-03 09:48:37,376 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-8-thread-31) [4ee81984] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to connect Host host2 to the Storage Domains ISO_DOMAIN.

(User: admin at internal) 

The iso domain is in the hosted engine: 
# cat /etc/exports 
/home/iso 0.0.0.0/0.0.0.0(rw) 
# ls -l /home/iso 
total 0 
drwxr-xr-x 4 vdsm kvm 32 Feb 26 15:11 240929ec-62e3-47ff-88b0-39cecc53ab8f 

Any idea? 

Thanks 

Jose

If you are managing the gluster volume through ovirt, you could just 
select the volume in the ui and click "Optimize for virt store". It does 
the job of setting the required parameters for the volume. 

Thanks,
