Hi Lionel,
Sorry for the delay in replying you.
If it's possible from your side, syncing the data and destroying old disk
sounds about right.
In addition, it seems like you're having this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1509629
And it was fixed for version 4.1.9. and above.
*Regards,*
*Shani Leviim*
