Re: FW: RW on init node's hard drive

As to NFS, are you running nis? Getting nis to work correctly on all 
nodes is tricky and that could cause problems on nodes other than 1. 
Also, do have a cvip address set up? What are the export parameters on 
the NFS server?

As to CFS, I know of no reason you shouldn't be about to create 
directories in a CFS file-system. However, I don't know as I ever used 
the option "errors=remount-ro". Could you try removing this mount 
option? (Depending on your distro, you may need to rebuild your initrd 
to make sure it goes away entirely.)

Thanks,

John Byrne
