When the OSD is prepared, systemd-udev kicks in since the device has been exclusively opened and thus reverts the permissions to root:disk. We need a udev rule to force re-applying the correct ceph permission so we can consume the disk. Closes: https://github.com/rook/rook/issues/8942 Signed-off-by: Sébastien Han <seb@redhat.com>
