[ovirt-users] Mix local and shared storage same data center on ovirt3.6 rc?

[Ivan Bulatovic]

Hi Jurriën,

I did some tests on ovirt-3.6-snapshot and mixing local and shared 
storage domains is working (with a tweak).

If you opted for Shared storage type when you created a new Data Center, 
you can mix NFS/FC/iSCSI shared storage domains with POSIX Compliant FS 
data domain using a local storage device (logical drive or partition, 
formatted with ext4/xfs). 

Only catch was, I had to chown the device node to vsdm:kvm for it to be 
utilized by oVirt (eg. chown 36:36 /dev/sda2).

It doesn't work on 3.5.4 though, I've changed ownership for the device 
node, had to change ownership for the ext4 fs itself residing on the 
partition, and it still refused to connect stating that not all ovirt 
nodes can write to it (that was expected).

I hope this helps,

Kind regards,

Ivan
