[Ocfs-users] problems creating ocfs filesystem

[Vicente Málaga]

Several problems when making it:
fisrt when I delete /dev/raw when i make raw -qa for verify then other raw 
devices using at the RAC say me:
rac01:/dev/raw # raw -qa
Cannot open master raw device '/dev/raw' (Is a directory)

So before creating the filesystem whith mkfs.ocfs i have to recreate /dev/raw, 
but when /dev/raw/raw41 disappears, when I try to make debugocfs or 
mounted.ocfs it say me again that /dev/raw/raw41 don`t exist.

There are any solution to say the kernel that all the raw devices tree, 
include /dev/raw and /dev/rawctl are at other place.

Thanks
