(perhaps right now probably involved in Red Hat Summit.. ) Anyway I see that Strahil already opened a bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1704782 And there is useful information inside it, such as that the problem is only on gluster and only if disk is created from webadmin GUI, while from rest API is ok. Also from 4.2 to 4.3 disk format (only on gluster) changed default from thin provisioned to preallocated. Hih, Gianluca
