Hi.

we had the similar issue with iSCSI & multipathd...

fixed it by adding new systemd service for afd that:

  • manages dependencies between afd and iscsi+multipath
  • starts: o after iscsi & multipathd o before ohasd

possibly, similar may help for your case too...

PS:

  • I fill that it should be managed internally by Oracle Restart/GI, possibly, with some additional configuration through crsctl ....
