Hello,

after upgradeing my whole cluster of 8 Hosts to ovirt 4.2.5 and setting compability of cluster and datacenter to 4.2 my existing virtual machines start using FUSE mounted disk-images on my gluster volumes.

One bad and slow thing I thought that I got rid of starting with 4.1.x finally !

Disk definition from virsh -r dumpxml VM of old running vm (not restarted yet !):

    <disk type='network' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
      <source protocol='gluster' name='gv0/5d99af76-33b5-47d8-99da-1f32413c7bb0/images/d5f3657f-ac7a-4d89-8a83-e7c47ee0ef05/f99c6cb4-1791-4a55-a0b9-2ff0ec1a4dd7'>
        <host name='glusterfs.mylocal.domain' port='24007'/>
      </source>
      <backingStore/>
      <target dev='sda' bus='scsi'/>
      <serial>d5f3657f-ac7a-4d89-8a83-e7c47ee0ef05</serial>
      <boot order='1'/>
      <alias name='scsi0-0-0-0'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

Disk definition from virsh -r dumpxml VM of new started running vm:

    <disk type='file' device='disk' snapshot='no'>
      <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads'/>
      <source file='/rhev/data-center/mnt/glusterSD/

      <backingStore/>
      <target dev='sda' bus='scsi'/>
      <serial>1f0db0ef-a6af-4e3e-90e6-f681d071496b</serial>
      <boot order='1'/>
      <alias name='ua-1f0db0ef-a6af-4e3e-90e6-f681d071496b'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>


How do I get back my gfapi gluster-based Disks ?
