For ACFS related question, see the solution documented in the MOS Note : ACFS File System does not Mount After Node Reboot (Doc ID 1552537.1)

some background info for ACFS start sequence:
 
During OS boots, and Oracle Clusterware is started and the following actions are taken;
OHASD loads the ACFS drivers and start ASM.

In ASM instance startup process, all the appropriate disk groups (listed in the ASM asm_diskgroup parameter) will also be mounted. As part of this disk group mounting process, all the appropriate ASM Dynamic volumes are enabled.

Lataer, the CRS agent starts up and mount the "CRS Managed ACFS filesystems"

CRS agents also start other resources. For instance the oraagent starts up the database. Note that in oırder to success in this step, all the resources necessary ASM, disk groups, volumes, and CRS Managed ACFS filesystems) for the database startup must be already enabled..
