GPT labels will use a PARTUUID to identify the partition, and I just confirmed that ceph-volume will enforce looking for PARTUUID if the JSON identified a partition (vs. an LV). >From what I briefly researched it is not possible to add a GPT label on a non-gpt partition without losing data. My suggestion (if you confirm it is not possible to add the GPT label) is to start the migration towards the new way of creating OSDs > > ср, 20 февр. 2019 г. в 16:27, Alfredo Deza <adeza@xxxxxxxxxx>: >> >> On Wed, Feb 20, 2019 at 8:16 AM Анатолий Фуников >> <anatoly.funikov@xxxxxxxxxxx> wrote: >> > >> > Hello.
