[ovirt-users] 3.6: GlusterFS data domain failover?

[Wee Sritippho]

Hi Nir,

Thank you for spending your time answering all of the questions. I 
really appreciate it.

Today morning, I'm, somehow, able to edit the existing GlusterFS data 
domain / add a new GlusterFS data domain.  Therefore, I created a 
replica-3 volume and added it as a new data domain, then removed the 
replica-2 volume as you suggested.

I though the problem in the 3rd question was gone and I won't be able to 
reproduce it again. However, after some amount of time, I'm able to 
reproduce it once more time :

This time, I can confirmed that both the host and GlusterFS was up in 
'gluster-status.txt'. I'm able to create any other storage domain except 
GlusterFS as recorded in 'ovirt-cant-add-glusterfs-domain.mp4'.
