Re: [suse-oracle] /dev/mapper ownershipt and permissions in SUSE 10

Maybe it is not of any help, but you should know, that RAC cluster 
components do not invherit secondary groups
from the 'oracle' user (at least, CSS daemon), so you should configure all 
devices (CSSFile and OCRFile) to be owned by the oracle
(including raw devices if you use them).
