The management of overprovision on a pool is no available in rhel8. the --no-overprovision option is not recognised by the stratis cli tool in 2.4.2 . this feature was introduced in 3.1.0 Recommend either remove this from the rhel8 documentation on this page, or update rhel8 to use stratis 3.1.0 or higher. Guessing a copy-pasta mistake from rhel9 docs ? Example: [root@redhat8 ~]# date Tue 20 Jun 05:54:58 EDT 2023 [root@redhat8 ~]# yum update -y Updating Subscription Management repositories.
