OCI: OL7 Leapp Preupgrade Shows Error “Inhibitor (High) for BTRFS RAID detected” in the Logfile
APPLIES TO:
Oracle Cloud Infrastructure
Linux x86-64
SYMPTOMS
While performing the pre-upgrade check for an OL7 instance before upgrading to OL8 via leapp, the following HIGH warning is logged in the log file:
Inhibitor (High) for BTRFS RAID detected
There are no btrfs filesystems used in the instance, but the kernel module is loaded as seen by the output of lsmod.
CAUSE
The btrfs module is loaded by the kernel in the instance, but it is not in use as there are no filesystems running btrfs in the instance.
The leap utility requires that there are no BTRFS filesystems or BTRFS module loaded in the kernel before the upgrade.
