Hi, If you run RHEL (or its rebuild), you can get the drbd-utils package that has the proposed fix. It is currently in the elrepo-testing repository. EL8: https://elrepo.org/linux/testing/el8/x86_64/RPMS/drbd90-utils-9.30.0-2.el8.elrepo.x86_64.rpm EL9: https://elrepo.org/linux/testing/el9/x86_64/RPMS/drbd9x-utils-9.30.0-2.el9.elrepo.x86_64.rpm Akemi
