The loopback approach is much better from the standpoint of data management. Once you have a directory dedicated to Docker engine, it's almost impossible to move it to a different volume, especially for the casual user.
Is upgrading to 6.9.0-beta25 all that is needed in order to fix this bug? I see from the change log it says this issue has been fixed. I currently have encrypted xfs on my array and my cache drive but from iotop -oa still shows loop2 writing excessively. I'm assuming I am just missing something obvious here....
I see one of the recommendation by @testdasi was to recreate the img to be docker-xfs.img as a work around.
