Re: how to disable ACFS from starting

Thanks Franky! I don't have any filesystem anymore to di-register, as I have deleted the one ACFS filesystem/volume/ASM diskgroup from one of my good nodes, so that I don't run into this same issue if someone accidentally reboots them. I have nothing under /dev/asm, as shown below:

[grid_at_hscpsdev3 ~]$ ll /dev/asm/
ls: cannot access /dev/asm/: No such file or directory
