Strahil,

Thanks for the follow up !

How did you copy the data to another volume ? 

I have set up another storage domain GLCLNEW1 with a new volume imgnew1 . How would you copy all of the data from the problematic domain GLCL3 with volume images3 to GLCLNEW1 and volume imgnew1 and preserve all the VMs, VM disks, settings, etc. ?

Remember all of the regular ovirt disk copy, disk move, VM export  tools are failing and my VMs and disks are trapped on domain GLCL3 and volume images3 right now.

Please let me know 

Thank You For Your Help !

Sorry to hear that.
I can say that  for  me 6.5 was  working,  while 6.6 didn't and I upgraded to 7.0 .
In the ended ,  I have ended  with creating a  new fresh volume and physically copying the data there,  then I detached the storage domains and attached  to the  new ones  (which holded the old  data),  but I could afford  the downtime.
Also,  I can say that v7.0  (  but not 7.1  or anything later)  also worked  without the ACL  issue,  but it causes some trouble  in oVirt - so avoid that unless  you have no other options.

Best Regards,
Strahil  Nikolov
