Hallo, has anyone a working tutoring how to migrate a centos 7 system from mbr to gpt without loosing data. My problem: A disk is used for docker images and niow this disk must be resized from 1,8 TB to 2,2 TB space. Three years ago when the system was installed no one thougt about this size limit. The system ist a centos 7 VM running on ESX 6.7. I found some tutorials but no one worked here.
Thanka for a hint. Ralf

Do you mean the boot volume, or some other disk?
I think your ability to do this, in any scenario, will depend heavily on your partition alignment. Where does your first partition begin?
Hallo, my testsystem for training this case is a default centos7 minimal installation. Later I ve to fix a server with 10 disks and disk number 3 must be resized from 1,8 TB to 2,3 TB. If it is possible it would be ok to configure a mixed setting.

Hallo, solved. ttps://polarclouds.co.uk/mbr-gpt-no-data-loss/ Ich tried it using disk sda for fisr tests. Using sdb as a non boot disk worked. Thanks for yours answer. Ralf
